  1. Hi, the man is right if the belt becomes damaged it can potentially get bits of debris into the lower part of the cam belt drive, game over, I think there are only three main suspects, 1, the auxiliary belt tensioner, this can be checked by observing the pulley whilst at idle and then turning on every electrical service available, aircon, lights, blower motor, if it starts moving thats your kiddie the motion of the jockey wheel should be uniform and level regardless of load. 2, the aircon clutch bearing, run the engine then turn on the aircon if the noise ceases then you have your answer, it's the electromagnetic clutch engagement that takes up any slack in the bearing. 3, the free wheeling clutch on the alternator this can be tested by removing the belt and running the engine. I wish you luck.
  2. Hi, the first question is have you had the light put out as the cataclean may have done its job but you won't know because most emission related faults will be locked in until deleted regardless of the cause being fixed or cleaned. With regard to the strip down by your friend you cant visually tell if the units working correctly however clean it appears, furthermore did he check the inside of the cooler?, these are often the source of the alleged blockage as these systems are very refined and twitchy because all the valves from 2009 onward use electromagnetic drive systems which throw a paddy if there is the slightest impediment of the actual valve movement, the old type vacuum operated had a propensity to stick open throw up no EML and just feed the cat and dpf the worlds supply of oil enriched exhaust gas until they failed as well. Then we have the turbo of which most modern diesels have they are normally variable vane, so you can imagine all that sticky stuff will eventually ruin that as well, prime example which I realise is not an Audi but the same principles apply, I had changed the egr on my Mondeo six months before I had to change the turbo, six months after that it kept throwing up a light and limp mode, the coding was for vanes sticking within the turbine, I phoned the company I bought the turbo from and explained my problem, they immediately explained it was probably the egr causing the problem, I replied that I had replaced the egr just over a year ago but the guy was adamant and stated that they would clean the turbo for a small fee, but guaranteed I would be back to square one in record time, I bit the bullet and bought a genuine Ford egr put that on and used a whole can of Lucas spray down the air inlet hose turbo cleaner, the old valve was stripped as it was redundant and with the valve in parked position the diesel I poured in leaked out revealing that the seat was not sealing against the valve, the liquid disappeared in less than twenty seconds and you could not see the gap with the naked eye and in view of the surface tension of the liquid which is definitely higher than gas, it wasn't doing what it was designed to. The end result was that it ran for another fifteen months or another 90k until I had to replace the ruddy egr again for the same reasons[ used as a taxi], I have racked up some 850,000 miles between the first three cabs I had, from the MK111 Mondeo euro 4 which despite my best efforts still smoked on acceleration like the HMS Belfast trying to escape the Bismarck, then the MK4 and MK4/5 Mondeos which had a lot better emissions set up but still lived up to the legend of the badge Fix Or Repair Daily, having done 50k since owning the Audi I am of the opinion that if the Audi is treated with respect and care they will easily out last the Ford.
  3. Hi, try opening the door and inspecting the latch mechanism, I had this with my A6 I use as a taxi, but mine was the other way round the door wouldn't shut, this was because the plastic coating they put on the latch had degraded and occasionally formed its own little ball and stops the latching hook from operating freely, after I got fed up with it one night I attacked the door latch mechanism with a pair of needle nosed pliers and derided most of the plastic that was hanging off and poked in a big portion of anti seize paste which seems to have done the trick, it seems to be a bit of a silly design when you in theory have to replace the latch because a two bob piece of heat shrink plastic has decided to play up.
  4. Hi Gents, I just thought I would throw this in. Many years ago I bought a Mondeo Titanium x Sport as my third cab, this was sporting 19 inch wheels with 40 series tyres which even though branded tyres they wore like there was no tomorrow, factor in the accelerated puncture occurrence and it was a recipe for bankruptcy, I was only getting about 4k on the fronts and 8k on the backs without punctures. I finally bit the bullet and bought some 16 inch wheels and tyres from my local tyre dealer, the wheels were genuine Ford off of a B Max I found a site on the net that gave the formula for tyre size to bring it up to the same rolling radius as the 19 inch wheel, anyway I engaged the help of one of my mates to help change the wheels we were a subject of fascination of one of my neighbours a German teacher at the local senior school called Gerhardt, he came over and asked what we were doing and when I explained he replied excellent!, it transpires he was a powertrain engineer at Wolfsburg for fifteen years his speciality was wheel and tyre combinations. He went on to say he had tested every wheel and tyre combination known to man on just about every model VW produced, he explained that as long as you use OE wheels the offset is the same its only the rim size/width that changes, economy vehicles use smaller width tyres and rims as this helps with fuel consumption due to the lower rolling resistance of the tyres, we then go to larger heavier vehicles that use a wider profile tyre but may still use a 16-17 inch wheel. he ends up going into his house to get some scales so we could weigh the 19in rims and tyres against the 16in wheel and tyres, it was a marked difference between the two the 19in combination weighed 5kilos more than the 16in combination, he then said can you imagine how much extra energy is used to turn the extra weight and increased rolling resistance, you will now get extra MPG, he was right about another 8 miles per gallon and the added benefit was no more tram lining on uneven roads and better still no more aquaplaning in heavey rain as well as only occasional punctures. I had to ask the question as to why they make these massive wheel/tyre combinations, he replied its what people want they think bigger is better, its not and sited the Mercedes E Class estates and saloons which were produced right up to the late nineties with 15-16 inch wheels and 70 series tyres with no compromise to the handling, as long as you use a minimum of 101 xl tyres you want have a problem and the tyres are cheaper and wear wise probably double the milage even on mid range tyres
  5. Hi I would consider the rain bit is probably coincidental, either way the only way to find out definitively is to get the car plugged in and get the fault codes read, my money as a pure guess would be on the gearbox needing a service, this is subject to a distant conversation I had with a mechanic I use who is very knowledgable and he suggested the DSG boxes are not suitable for a cab as due to the required service frequency times my annual milage would equate to more expense which is why I bought a manual the gearbox oil gets changed once a year and no filters etc are required.
  6. Hi Gents, after a year almost of lock downs and a thin amount of work in the taxi trade I had finally reached the 80k mark and having read the service history for my car I was not to worried by the cam belt situation as the service history claimed that the belt kit was changed at 40k under warranty because of a squeaky idler pulley bearing, that said I did actually phone the dealers in Manchester to see if it tallied up with the print out of the worksheet I had, the service manager was very reticent to talk at first until he realised I was not trying to bag any freebies and just wanted information to form my own service schedule, he explained their definition of belt kit which was belt, tensioner, idler pulley and they wouldn't have changed the water pump as the recommended milage interval for that was 110k. I felt I might be able to force the changing of the cam belt and water pump to about 90k, then the sudden cold snap we have had forced the issue, only a two mile drive to base but a total absence of warm air, in fact it took a further fifteen minutes of idling to get any lukewarm air, all this equated to a massive increase in fuel consumption, I had second guessed that the thermostatic pump cowling had become jammed open which was proven correct when I had the belt and pump changed today, thank god it had not jammed shut as overheating is not a favourite past time for a CNHA engine. When I was down to pick my car up I met my neighbour who had his Q5 in the work shop, back in the summer I had noticed a rather rotund mobile mechanic hanging in the engine bay of his car but did not think anything of it, it transpires the guy had changed the cam belt at Audis recommended 110k but not changed the auxiliary drive belt as he said it looked ok, the belt had eventually shredded itself and fallen off, a breakdown engineer fitted a new one but by then it was to late as the debris from the old belt had gotten behind the cam belt shroud and made the cam timing jump one hundred and eighty degrees, the thing now was devoid of compression even after new belts fitted so they had the rocker cover off to find the bent valves, I don't think I ever want to see that far into my engine, I always change my ancillary drive belts every thirty thousand and when the cam belt is replaced regardless of what they look like, I honestly believe if I buy ten belts during the time I own my car it still won't come to the eighteen hundred quid the poor sod with the Q5 is looking at and thats if none of the valve seats is cracked. There are some very wise people on this forum who recommend 80k or four year belt changes which duly noted as well as the advice on using OE parts from companies like TPS who definitely don't have the same sense of humour as the dealers, so a word to the wise DONT forget the humble ancillary drive belt which lives in a very hostile part of the engine bay and for the sake of £20 for the part could end up costing thousands. Regards Steve.
  7. Hi Thomas I had heard of this problem after I bought my A6 but I checked on the gov mot website and you get a link for outstanding recalls on your vehicle as per your registration, there were none plus the fact Audi have been contacting even third generation owners to let them know of this if their vehicle is affected. Its to do with the electric auxiliary pump getting clogged with debris or leaks in to the electrics and the thing can self combust but I really would not be worrying as it will have done it by now or you would have had the letter, ask a few Octavia owners circa 2013 those used to do pumps on a regular basis, the debris excuse is code for we bought the pumps from a cheap supplier. Steve
  8. Hi Gareth, I knew about the ethanol as I live near Dunton and a very drunk engineer was explaining that they had been trialing an ethanol fuelled Focus, great mpg, nil emissions only problem was fuel leaks because the ethanol had started to rot the granny out of the pipework plastic and metal and then turned its attention to the fuel pump seals, after a few months they gave up because it had started degrading valve seats and pistons, I think localised hot spots in the swirl bowls on the pistons were mentioned. I can understand the concern with older vehicles as the internal castings were never intended to cope with the combustion power of ethanol, I once met a very old flight line mechanic who was in France at the beginning of the retreat to Dunkirk, he explained they were trying to get every available Spitfire that wasn't damaged back to the U.K. The only problem was lack of fuel, the standard hundred octane wasn't available so the French gave them this stuff called Essence B which as it turned out was full of ethanol, it worked to get them home but every pilot noted that when they throttled up the engine felt like it was trying to climb out of the airframe, the old guy explained that all the aircraft that used this fuel to get back had an immediate engine rebuild, ethanol can be lethal if used in the wrong dosing but I doubt the fuel manufacturers care much for older vehicles which I would consider to be made a criminal offence
  9. Hi Gareth, they can't eradicate sulphur from fuels completely as this will cause terminal problems with the lubricity of the fuel, sulphur is not in itself a lubricant but when burnt causes a reaction between nickel and other metals present in the engine metals to form a Eutectic alloy which has a very low melting point and helps with friction, self lubricity, as far as I am aware the current sulphur levels in European fuels are at best 10ppm. Other countries in Asia have reduced their levels of sulphur to 50ppm in an effort to reduce pollution, in South Africa they tried to drastically drop the level of sulphur this caused problems especially with diesel powered vehicles causing premature wear and seizure of engines in older vehicles so they started to put mineral based two stroke oil in with the fuel to help with the loss of lubricity then developed the scar test for imported fuels to make sure the lubricity of such fuel met the criteria suitability for their country. The problem with using two stroke oil as a lubricity agent is it works fine as that but when mixed with fuel especially diesel it forms an aluminium oxide which is good as a lubricant but a total failure when it clings to the inside of the injectors and clogs the injection ports which in most modern diesels are smaller in diameter than a human hair, this allied to the fact that the AUDI injectors are piezo operated and can inject up to five times in one cylinders cycle to control emissions and balance fuel usage between the other three cylinders, therefore it wouldn't surprise me if they had put some other synthesised sulphur product in the fuel to accommodate the newer engine designs and it did not work with older engines, basically it comes down to the discussion on this thread being about the duality of human nature when it comes to money. Steve.
  10. Hi Steve, my grandads most used saying was you are never to old or clever to learn something new, today I have, I was unaware they had started adding sulphur to the new petrol and am I missing the point, the whole Dirty Diesel campaign was started off of the back of the large amount of sulphur in the fuel and once the fuel producers had eradicated that the powers that be started on the nox emissions which the manufacturers more or less cured. Now it looks like they are going after the particle emissions post DPF this one is proving far more difficult to implement as the technology to do this costs hundreds of thousands of pounds and would wipe out most MOT stations financially. Grandads other saying was you can always tell when a politician is lying, their lips move.
  11. Hi I have found through experience that the independent specialist are nearly as expensive as the main dealers, if I were in your place I would find a small local independent garage and get a second opinion on the bushes, then if there is an issue with them get them to price the job using mid range aftermarket parts Febi,ACP,Meyle in view of the fact that you are going to get rid in a year as long as you don't do starship milage these parts are pretty robust.
  12. Hi is it an independent garage or a dealer, sounds a bit steep for standard bushes but if they are Polyflex bushes the kit alone is a bit pricey, but I can recommend these as used them on my Ford cabs I owned as the sway bar and lower arm bushes were notorious for tearing out but having gone to the expense of buying these bushes on the last car I never had a recurrence of these problems for the next 160k after which I sold the car to a mechanic at my local garage who has had the car for over a year and never reported a problem with these items when asked, other than that shop about.
  13. Correct at every level, its a known fact that petrol engines produce more C02 than diesels but from the government perspective its better to jump on the Nox band wagon as there are more diesel owners to tax to death, just look at the Ford CVH engines during the late seventies early eighties how economical they were, only problem was that these lean burn wonders C02 reading were off the Richter scale, that all stopped when CARB in America got more proactive globally with CATS and injection systems that were controlled by the ECU within very tight peramiters. Fortunately Adblue has scuppered their assault and attempts to tax us into oblivion, no one seems to realise they will start on hybrids next and when the have eradicated all fossil engines just look at the potential for making electricity the most expensive commodity on the planet.
  14. Hi, totally correct, if the car is getting extra air from a source other than the air box the engine management system will demand more fuel to stop the engine from running lean, most default strategies that the ECU has at its disposal will do this as lean burns valves and pistons, until it reaches the point where it can't call up enough fuel to deal with the air , then the lights come on. I can agree with Envy that the soot is most probably a separate problem.
  15. Yes indeed, just seen the advert inserted in the middle of this thread, can't understand why the owners of the cars affected do it most of the people I carry that went for the free VAG retro fit reprogramming now moan about what a dog the car has become performance wise and I have even had many telling me the vehicle concerned does less to the gallon and they were going to sell it. Have we really become that stupid that if something isn't broken we will try and fix it even if it costs more money in the long run, still I suppose you could use the money you get back minus the leeches third to fund the extra diesel when is all you had to do was wait until you got a newer model of the same with even more power and less road tax, try running Fords as a cab as I did and enjoy the Jackanory quoted mpg as well as the stratospheric VED hikes every year, I ended up getting an Audi as at the time it was cheaper than the equivalent Mondeo Vignale I went all the way to Oxford to see and had 20k less on the clock, won't be going back to any other make any time soon.BTW Sorry about the prose transgression.

  16. Hi Gents, anyone else noticed the sudden surge in the number of parasitic claims companies dealing with the potential fleecing of VAG for over indulgent compensation, it sort of hit me in the face the other night when I had some misinformed !Removed! in the cab bellowing at me about how much I can claim through the emissions compensation scheme because I drive an Audi, I didn't bother to inform him that it was only for cars built 08-15 that would have been a shade to much education for the self appointed expert on Compo, his exact words were, you could get Fowsands of pands out of them, if the journey had been longer and the client more sober I would have put my theory forward. How many of these owners of the targeted years of vehicles suddenly found via market depreciation that they could actually afford an Audi and went and bought one, then they drove round for the next few years marvelling at the reliability, economy and handling of their purchase then all of a sudden they develop a Thunberg type conscience at the mere mention of money, after they get paid out will they scrap these filthy polluting vehicles, probably not, lets face it folks its not like PPI where they were releiving you of thousands for something that definitely was not going to work, no, what people got was something that was usable and gave good service and in the final analysis if they were handing out prison sentences for dodgy motor manufacturers practises most car brands CEOs would be doing life, the bare facts of the matter are most everything you buy in life within its history will have some sort of rule bending attached to its production to enhance its appeal in the market place as well as lowering production costs, this saint like reaction from the motoring public is sadly endemic of the vile claims culture that is permeating society, Stevey.
  17. Finally got round to changing my rear wiper motor, what a mission that turned out to be, not so much changing the actual motor but getting the plastic trim back on I expect most people on this forum have come across the sprung metal clips that hold the main part of it to the tailgate it would appear that these deform rather easily when the trim is removed and require the worlds supply of manipulating with bull nosed pliers to correct the shape for refitting. Found it easier to sit in the boot and pull the tailgate down until almost shut then slide the top part of the trim into position then push the clipped part into place, I lost a couple of the spring fixings and was wondering how much Audi were likely to rob me for another set, deep joy I found them on eBay three quid for ten plenty of spare clips but I suspect the clips are of a one use design.
  18. Hi Thomas, glad you got it sorted and the heartwarming news of the DIY service makes me glad at least the thieving scrotes at the garages won't be relieving you of a ton of cash any time soon, I knew you were more than capable by the way you describe the problems you had a bit of savvy goes a long way. I am off to tackle the dreaded rear wiper motor which keeps stopping when it rains because some moron designed it so the water washer system comes through the middle of the wiper spindle and when the seals get older it runs back into the control box and rots it out, I definitely aint taking it apart and cleaning it up only to get the same problem this winter, just going to get a new one as if you work out how long the original unit has lasted it will be another four years until the new one expires. Regards Steve.
  19. Well now heres a thing, after going through the drama of re educating the the headlight level I noticed today that when we pulled in against a wall at our local supermarket it was almost dark because of the storm clouds and trees overhanging that part of the car park, whilst waiting for my missus to go and pick up her order boredom is a terrible thing, I started looking at the light beam alignment against the wall, the nearside light which I adjusted is now in a position where it would be good for shooting roosting pigeons at night and it would appear the start up self levelling sweep is now working, I thought maybe the heat this week had baked it back to life but remembered I had been rooting about under the n/s front plastic scuttle cover there is a box in a plastic shroud under the vent intake which I could just about reach the connector to give it a wiggle no more than that, I haven't driven in the dark since so I wouldn't have noticed any change, my guess is I have found the light reach module and it has a cruddy connection because some Div has stuck it in a place where it can get damp, therefore on my next day off I will have it out and clean the connector.
  20. Well I suppose if you don't drink, smoke or run a high maintenance woman why not, I find Stuarts honesty refreshing as most people would just blush and keep quite about it all as it didn't quite work and its embarrassing. Case in point a guy I know had bought a brand new Vauxhall Corsa for his beloved son to drive back and forth from university, Jnr was definitley not impressed by 70mph on the motorway and got one of his mates to help him find a remap specialist who apparently did a first class job until it started running like a bag of nails, he mentioned this to dad who had paid for the car, dad considers that the next weekend Jnr is home he will book the car in on the Saturday morning at the dealer he bought it from, this will do Jnr a favour as when he crawls out of his pit the car will be fixed, good old dad. This all went horribly wrong the second they fired up the diagnostics live data, as this was a warranty claim the dealer went into hyperdrive trying to find out what was wrong, dad was rudely awoken by the service engineer and manager telling him his six month old car was no longer under warranty as someone had been fiddling with the ECU and he owed them for the diagnostic and inspection, furthermore if he wanted it back to normal this would involve a new ECU and about two grand to put it right, that was when he rang me to ask for a second opinion, I spoke to the engineer at some length who explained that they get this all the time with youngsters cars to the point where Vauxhall had a special program to trace the original mapping and any map track ghosts left by a plug in the OBD port remap like Blufin. The guy paid for the repair and told me Jnr when questioned had said he didn't think it would matter and thats why he had not mentioned the remap, most cars that have had remap if you admit its been altered the main dealers and some specialist won't entertain woking on engine problems because of the diversity of mapping profiles used by these expert remappers who would claim to know more than the people who make the cars.
  21. Hi Thomas I did send this twice but please receive the following, 4H0941285G Leveling sensor LEFT 4H0941286G Leveling sensor RIGHT Try this Blueprint number for your filter ADV182343. Steve.
  22. Hi Thomas the part numbers were sent to your inbox last night will resend
  23. Hi Thomas going to be out of the loop for a bit as I am off to work but I hope the part numbers got to you ok and will do some cross matching on the filter applications tonight. Regards Steve.
  24. Hi there is no way of testing the workings of the control box without some pretty sophisticated kit, just had a word with the guy up the road he said sometimes they disconnect the sensor at the bottom arm end and tie the arm at approx level with a bit of gaffer tape then drive it if the fault does not appear thats your kiddie, the part no is on the unit if no joy message me with your vin and I will look for the part no on my new toy, there are loads of them on eBay and the prices are not spiteful new or second hand and according to those who know they are plug in and play, no coding.
  25. Looking at it again it looks as though the allroad has a levelling sensor on all four corners having picked the guy up the roads brain he works for a independent garage and reckons it could be the sensor as you said, apparently they are not very robust and operate internally on a windings system that if stressed can fail I.E. if the wishbone is hanging down while changing the discs, rarely it can be crud in the connector but it might be the internal pick up inside the box has gone beyond a limit it was never designed to go and is now playing up which concurs with the error appearing when driven and the sensor is moving. That was the thing that baffled me with my light problem the car has no sensor on the front and no signs one was ever present I am looking at the possibility that the levelling sensors are built into the headlamp but have yet to find the triggering device, all good fun.
