Hi mysterious one this, its definitely not the turbo as this has nothing to do with the EGR if you could post a picture of it that may well shed more light on the subject it sounds like a blockage somewhere as thats the only time I have seen them fracture especially when some Div has blanked one end off.

Hi its either 5 or 7 if they are rubber they are the most likely to fail as they live in a world of cr@p from the unburnt gunge from the PCV valve, good skills with the diagrams. Steve

Hi Car Supermarket, was it the Aldi version I would swear on a stack of bibles that is the old belt I have Never seen a belt in that condition after that milage, I agree with Gareth get the car recovered to Audi for a proper engineers report, it definitely won't go the garages way, then take them to the cleaners via trading standards, you will have them by the short and curlys, I would also recommend if the garage offers a repair that you DEMAND that they pay Audi to replace the belt as quite rightly you have lost all trust especially after they quoted the old cookie of 75k, they must have forgotten about four years? as for the parts being hard to source thats Scallops, if they had bothered to ring the local TPS they would have delivered O.E. parts the next morning, but its cheaper not to do the right thing and just hope if they lie enough you will go away, UTTER SCUM. Steve.

Hi can't sue you under the trade description act about the weather, the turbo won't have to come off but I should imagine removing the trim above the intercooler is a raging possibility, if you PM me your model and VIN I will see if I can get a ball park diagram off of my parts system, normally the main suspect runs from the other side of the turbo to the intercooler then from the exit side of the intercooler runs to the throttle body if you get a good visual on the intercooler the rest becomes apparent. Steve.

Hi you will have to get the car scanned for faults, there is no magic way of guessing what your problem is without P codes. Steve.

Hi find a place that uses Hunter for wheel alignment equipment and a good one only charge for the wheels they have to adjust. Steve.

Hi in all my years I have never known anyone to use the old belt again thats shocking, its an unwritten rule that if you change anything thats to do with the timing belt, water pump, idler pulleys etc you always put a new belt on REGARDLESS of what you view its condition to be, the belt should be changed along with everything else every 80,000mls or four years max, it has nothing to do with over tensioning those photos are a classic case of age deterioration which causes de lamination, example my old Mondeo taxi had developed a water leak from the water pump, the whole cam belt kit including pump had been changed 20,000 miles before, the pump was a warranty job but I specified a new belt at my own expense as that was not covered as it had not failed, for the sake of £24.00 for a new gates belt it was no major consideration, I covered 340,000 miles in that car and never had anymore problem with the belt. The garage mechanic you bought the car from needs stringing up anyone with half a brain would have looked at that lot and advised changing the whole lot but lame brain decided just to change the idler, its cheaper than paying £200 for a whole new kit and the labour costs as well, please tell me it was not a dealership you bought it from. Steve.

Hi it will probably fit but buy a 2011-2018 one it will be cheaper. Steve.

Hi try giving the button a good clean with contact cleaner or WD40 and work it in and out failing that buy another second hand washer stalk. Steve.

Hi try any breakers parts request site on the internet. Steve.

Hi as its a Q7 I would be looking at what the warranty covers in detail judging by most of the posts on the Q7 forum it may well be the best £2.5 you ever spend. Steve.

Hi you only re adapt the G450 sensor if it is a new one and its a lengthy process as you have to regenerate the DPF a couple of times before fitting to give the new sensor almost zero soot in the DPF to give it a chance to learn its values from scratch, the other sensor with the pipe that hangs out with no home is a G505 sensor which measures soot loading against outside barometric pressures, personally I wouldn't bother with G450 UNLESS ITS NEW as it must be working ok to have picked up the fault in the first place. Steve.

Hi if thats the number they gave you it should be fine, if not that will be their problem. Steve.

Hi no worries I am sure you will find one, Ford wanted £300 for a new tin sump so £80 for threadworx was a no brainer, let us know how you get on. Steve.

Hi just the section where the pipe joins the turbo, on another tangent you described an induction roar when accelerating , a split boost hose between the turbo and the intercooler would make the same noise as its loosing boost pressure which will put it in to limp as its also classed as an air leak within the code you have its one of those lousy generic codes that covers a multitude of things. have a look at the boost hoses either side of the intercooler. Steve.

Hi it was just the EGR valve I re adapted, go through the menu on basic settings address 6 on my version scroll down to low pressure EGR adaptation and press go watch the numbers going up and down when it stops wait two mins and press done. Steve.

Hi the last thing to try is fit the new duct clear the fault, without driving it let it idle and get nice and hot and do a forced regeneration with the OBD. Steve.

Hi sorry the EGR valve was VDO, the cooler was replaced off the back of p2002 and was a previously enjoyed unit from eBay which I super cleaned with carbon cleaner and Mr Muscle, its just unfortunate we have two EGR valves, the low pressure one in the DPF and the high pressure one on the intake manifold which I have never had a problem with because thats the easiest to change, Murphys Law. Steve.

Hi you can re tap the hole if you have a tap/die set but I would be inclined to contact your local mobile thread repair service they can supply the right size bolt and is all you need is a copper washer to fit, the last one I had done was a tin sump on my mondeo so fitted a slightly bigger washer on the plug thread side so is all I ever did after that was fit another washer every time, thats why I am a fan of the little electric oil pumps that suck the oil out through the dipstick, also the thread recovery people do the job without removing the sump, one of mine I did I used an old spark plug with the top snapped off as a temporary repair until I got a suitable 19mm bolt, if its an alloy sump they are even easier. Steve. Steve.

Hi Jon well over a thousand miles and its behaving itself, I had to re adapt the valve on the cooler as that was new and that took about five mins its definitely got its MOJO back and I am getting good mpg even with the aircon going, still persisting with the Archoil as the way I am looking at it is if I got 125k out of the last cooler so chances are the replacement should do the same, I was wracking my brains as to why my one leaked and today I found the answer from a lorry fitter I took to a wedding reception, apparently they have this problem as well, it starts with the cooler blocking which then traps crystals in the cooling tubes the steam from the next spraying of adblue [35% Urea 65% distilled water] then dampens the trapped crystals and they start to rot the cooler tubes, I looked this up when I got home and sure enough adblue is harmless to the environment but will be corrosive to most base metals which is why the feed pipes are high quality plastic and the spray nozzles are high tensile steel which is chromed, I paid £120 for an O.E VDO valve just because it didn't have the VAG logo which is better than the £350 that Audi wanted, so if it all holds up barring the labour it was a cheap fix, still working on the catch can thing as lateral thinking says if you can stop the extra water getting in it will cut down on the steam supply to the cooler. Steve.

Well done Gareth you can't keep spoon feeding information and trying to draw maps, I am currently in the process of buying a Ford Kuga that has been sitting on someones drive and has had a whack on the front and looks like it just needs a new dash/airbags and a bolt up on the front, I went and knocked on the front door a couple of times and was finally accosted by a neighbour who asked me what I wanted he said he would pass on my interest and phone number, guess what the owner phoned me two days later and we are now negotiating, amazing what a bit of persistence will yield. Steve.

Hi see, no new seat well done.

Hi its definitely the rubber section that joins the duct to the turbo, I used to get this a lot on the two Mondeo cabs I ran and after getting Pixxed off with keep paying £150 for a new inlet trunking just to get the rubber boot I finally measured the old ones I.D. Both ends I finally bought a stepped section of silicon hose that was within 2mm of the right size both ends I.E. one end was 52mm the other was was 48mm these are called reduction pieces and are available from ASH Silicone hoses on line and for about £16, that put it to bed for the next 150,000 miles until I sold the car, you might even be able to buy the boot as a repair section on eBay. Steve.

Hi the DPF is Finland your problem is nothing to do with the Adblue delete, garage diagnostic systems are Generic and won't show the reason for the code P2002 which is the EGR low pressure cooler, no one can do anything to tamper with these, the EGR they turned off was on the high pressure side on the inlet manifold you actually have two EGRs one high pressure one low pressure its that which is causing the problem, as far as I am aware no one has written a software to disable this as without it you would definitely fail an MOT on the emissions as the low pressure side is part of the Ultra technology and thus the emission maximum is 0.05 maximum, mine went and please see pictures of what it looks like and why they fail. Steve.

Hi its not that steep when you consider it will have to be sprayed fitted and then blended in to the wings and any other associated panel, if you just spray the bonnet and don't blend it in after which they will have to mop it to make even the difference in the worn paint and new will stand out like a Bulldogs ghoulies. Steve.
