Hi its the turbo position sensor which is on top of the turbo this sends messages to the ECU so it can fine tune the amount of boost to the engine at any given time, this sensor gets to control the vanes on the turbo but if the vanes are sticking it will struggle to open and close them and increases its voltage [circuit to high] to try to achieve optimum position, try giving it a can of Lucas EGR and turbo cleaner to free the vanes up. Steve.

Hi it sounds like a failing injector or a sticky EGR best to get it scanned for codes. Steve.

Hi BEM systems were fitted from 2004 on most models except on some entry level A2s and have to be coded, if it was fitted by Halfords it should have been coded except at the two local Halfords in my area when I enquired about my daughters Q3they were perfectly happy to sell us a battery and fit it for an extra £20 but when I enquired about coding they went a bit sheepish and said we don't have the equipment to do that, buyer beware.

Hi best way is buy a cheap arm puller off of eBay, Sealy are not a bad shout, hose it down with Plus gas penetration fluid leave overnight and then use your puller you might need a pair of Mole grips to turn the compression screw but it will come off. Steve.

Hi best practise is to remove the drive belt and then try it, carefully spin the idler pulleys and check for any roughness as the bearings are rotated if they seem okay and the noise is gone when running its either the alternator clutch or an internal bearing in which case you might be better served getting a reconditioned unit as you will need special tools and a world of patience to strip your unit plus a rebuild kit, not cheap, the replacement option is a lot cheaper. Steve.

Hi check behind the cam belt cover as it could be a leaking camshaft seal the angle of the oil throw from the belt looks about right and iff its sucking air into the head area that would cause the smoke as the crankcase pressurising would cause excessive amounts of crank gas to go into the PCV system. Steve.

Hi its the bulbs, pound to a penny if you put standard bulbs as a retrofit it will stop, even if the bulbs fitted are can bus error free the one thing they don't like is a dose of pulsed current feed, I have seen the H4 leds fitted to fiesta mk6s blow when they keep flashing the main beam to often. Steve.

Hi Steve what an absolute belter of a comparison we all remember the end result of that one, a short sharp battle and I wonder what happened to my mums neighbour who was the first to buy Betamax unit and was always harping on about how much it cost, mind you it was the same neighbour who bought a brand new Moskvich a few years earlier and collided with a house at the end of the road about a month later after the pedal box had rubbed through the clutch cable, there is no depth to which human stupidity will not plummet. Steve.

Hi Steve you are not going all Bertie on us and investing in a Milk Float, this forum would become pretty lame if all we had to discuss was possible braking and suspension mods, Snap On have just released the first socket set for electric cars as the bolts etc on these cars is completely different from conventional cars, its a snip at £1400.00 for a sixty piece set. Steve.

Hi Gareth you don't just buy it because eBay compatibility graph says it will fit, if you have the correct parts system it gives you the part number of the part your car was built with with the supersession numbers which will have different letters at the end of them but will still fit your vehicle, if any of those numbers are on the listing as o.e. numbers it is safe to buy the item, if you are still not sure message the seller they will confirm/deny and if its still the wrong part, it won't be sitting on anyones shelf as you send it back, you have to have the correct number in the first place along with any supersession numbers, E.G, I obtained my daughters cam belt kit from eBay the part number matched but the sellers cross reference said it wouldn't fit so I asked the question and they came back with YES IT FITS, although when it came I checked it but the part number had different letters at the end and stated it was for a Skoda, so did I send it back [NO] I just got it fitted to a Q3, its called Globalisation make a part which fits a range of VAG vehicles but give it a different letter at the end and they will tell you that because the letter is different it won't fit your Audi which has the same engine with a different engine cover, you just have to have the Right number in the first place and it shouldn't be from some random parts catalogue on the internet whats known in engineering terms as RDS reliable data source, anyway the Skoda belt [Dayco brand] has been whizzing round for the last 700 miles with no problems and I don't see any future problems as Dayco is an o.e. supplier even if it is for a Skoda on the packaging, its all smoke and mirrors. I don't know where you got the number for your belt but something is badly wrong with the information. Steve.

Hi try the activation plunger switches on the doors and see if there is any power to them as they work the interior lights when you open the door try this with the headlights on, other than that its a case of chase the ace with the wiring from the fuse onward. Steve.

Hi the power even if present will only illuminate the bulb when the switch is in the on position and the earth side is now in play the power should always be present to enable this function. As you just stated the power is fed to the switch therefore no power supply to the unit it won't matter what position the switch is in. Steve.

Have you tried Quick Fit, my local branch have the latest Hunter kit with the specialist cables for VAG cars I asked the question about anything special about Q7s and he said not most VAG models fitted with adjustable /pneumatic suspension are all the same, as for one adjustment affecting another how does that work! if the rears are in the green zones measurement and only one front is out why would they have to adjust the backs if its only the front needs doing, as long as all the wheels are in the green zones at the end it does not make sense, I.E. the backs are ok which is the datum point how does adjusting the fronts into the correct parameters make the backs suddenly go out of alignment especially when you consider the bolts on the rear are very tight so what moves, Quick Fit are about the same price but I would say find an outlet thats not terrified of its own equipment, in the final analysis they should only adjust the wheels that are out. Steve.

Hi if there is no power going to the bulb holder it won't matter what position the switch is in, looking at the picture of the fuse box what is the random DIY wire about it may be that someone else has been having a go, my only suggestion is to run a new live feed in from the correct side of the fuse if it is showing power across the fuse, alternatively run a live feed from one of the spare fuse stations that has power one side but from reading the first post I would be checking the earthing first. Steve.

Hi Don, no mention of the dipstick on my system, found a bit of a heath Robinson multi vehicle system made by Sealy but its not practical as you can't leave it in situ, Audi want £120 for their item but I have found loads on eBay a lot cheaper under the following part numbers, original part number is,03C 907 660 Q, The supersession number is, 03C 907 660 AA, as I keep telling Gareth the letters are an update of the year of part build and it is the same part with different letters as you will see when you plumb the part number into eBay they state that both of the numbers are O.E. and will fit. Steve.

Hi what a load of old flannel, no weights involved if you find a place with the latest Hunter kit it comes with a plug in module that resets the steering position sensor and checks the ride height on the pneumatic side of the suspension, Audi will do all of this but the setting up of the equipment is time consuming therefore most of the charge at the end is labour, the two most major considerations are the correct camber and toe in/out, on the correct Hunter device the manufacturer optimal settings are displayed along side your own real time settings so when adjustment is made if any, your setting block will turn green when the correct measurement is obtained, I am reliably informed that Kwick Fit and National tyre service are equipped with this latest equipment and are somewhat cheaper than Audi who are allegedly currently charging around £500+ for this service, having looked at this I am glad my A6 has standard national health suspension as if you own a top of the pops A5 Q7 or any thing else with adjustable suspension/ride height you are supposed to have this done once a year or whenever you change tyres. Steve.

Hi have you checked the cam belt, the symptoms sound as though the timing may have slipped especially as there are no codes. Steve.

Hi if you go to a wheel and tyre specialist with the Hunter equipment they should be able to do the work without to much drama, the peculiarity with German cars is that both camber and castor can be adjusted at both ends unlike most other brands where its only the camber that is adjustable, if you find a company that actually specialises in wheel alignment they should be able to do what you want without drama, I recently had my car four wheel tracked and it only needed a tweek on the n/s front to make it perfect, after all its principle is to align the front wheels with the rear as the rears never move unless you fit new parts as in when bushes fail on the rear suspension and even then it won't be that far out as manufacturer tolerances on suspension brace arms etc are pretty good. Steve.

Hi Don you will only get the dipstick from America I tried with mine but if you factor in the postage and possible customs charges it is cheaper just to buy the level sensor, I will see if I can get a part number based on your VIN. Regards Steve.

Hi the thing thats got me baffled is that you have hot air coming out of some vents and not others if the heater matrix pipes are hot and you are getting hot air I would lean towards the climate control as if you had an airlock that was in the matrix they would all go cold, how far do you have to drive to your wifes work as I know for a fact in cold weather my cars top hose is still cold after 20 mins of running it takes at least 30 mins to get to what I class as hot, no problem with cabin heat as the auxiliary heater takes care of that, the only thing I have ever had that caused prolonged heating up problems was when the water pump thermostatic impeller shroud got stuck open so it took about 50 mins in really cold weather for the temperature gauge to go up. Steve.

Hi Martin I think the best course of action would be to get the car read for codes, my pure guess is it could be turbo related or the clutch pedal switch sending dodgy signals. Steve.

Hi glad its sorted out, just goes to prove electrical problem are a real can of worms. Steve.

Hi, well done Karl, its been a long battle but victory is a sweet feeling, top marks for persistence as you now know it pays off in the end. Steve.

Hi all models from 2004 need a BEM recode but almost any of the diagnostic platforms can do this using the original BEM Code and changing one digit it thinks its getting a new O.E. battery and as long as the BEM is happy life is good. Steve.

Hi have you changed anything on the coolant side?, if not it could be the climate control unit playing about, Audi recommend vacuum filling of the system which would indicate no bleed valve the only models I know that have a bleed facility are the petrol driven cars. Steve.
