Fair enough. If it had been an after market radio it could have been wired into the wrong power supply. That cause is now eliminated, and I don't know what else to suggest except an auto electrician.

Do you still have the original radio fitted, or has it been changed?

Forgive me butting in Chris but you seem to be turning a blind eye to Magnet's strong hints about the state of your engine, so let me be more forthright.

Running the engine for a year without adequate lubrication has spoiled the piston ring sealing in the cylinders as your compression figures clearly demonstrate. (Incidently that's likely to mean the big end and main bearings are also clapped out.) No amount of new oil pumps are going to restore the rings and bores, so there will be exhaust blow past leading to smoke, high emissions, blocked exhaust and MOT failure.

I fear you have left it to late to save that engine.

"Computer says no, so you are a liar" is an all too familiar response from Audi recently.

Thanks. That noise could be many things. Does the noise change when the engine is revved in neutral? Does it change when revved under load?

If you want an original Audi seat better ask Audi. Other than that an internet search showed many companies making seat covers ranging from loose slip over types to custom made. Bear in mind that your old upholstery may have faded so it will be difficult to match the colour.

Sorry Mark. I will not download anything from untrusted sources. If you can put the video on Youtube for example I'd be happy to look at it there.

Ye Gods! Is it not being done under guarantee, and if not why? As Magnet mentioned, the car should still be under warranty.

Do you have an update for us Russell?

Please do.

The stink of burning rubber often indicates a belt is slipping.

Transient faults like that are a devil to diagnose, and as you know, replacing parts at random could cost you many times the value of the car. I suggest you get it professionally tested as some code readers are better than others.

If you believe the suspension is defective, get it tested. If the test proves it to be normal then you have chosen the wrong car and need to either upgrade the suspension or buy another car.

How soft is soft? Ones man's soft will be another man's firm. The matter is so subjective that the only sensible thing to do is try an identical car as a comparison.

It depends on the left/right balance. If the left speaker is set louder than the right it will be the first to fail.

Speaker damage is often caused by overloading. Do you often have the volume high?

Scrutinise the exclusions very very carefully. Most of these policies are not worth the paper they are written on.

That seems to be normal for such companies. If you can not do it yourself you will need to get a garage to do it.

Is thus the same boot on the same car that you reported as fixed an hour ago?

Thanks for letting us know.

I can't help on that score. Do please let us know the outcome.

  I do think, it's likely that there are more cars out there with the problem, just finding out solutions worked. 

Even that could be an expensive waste of money. Just because another car has the same symptoms as yours does not mean the cause or its solution is the same as yours. Diagnosis is the key to getting a repair at the lowest cost.

If your current Audi specialist can not find the problem, find another specialist.

I agree that a 12 tooth pinion would have 11/12ths of the mechanical advantage of an 11 tooth pinion if all other factors are the same, so does the replacement motor have increased torque to compensate?

Brandon.

In your position I would not be worrying about a wiper/washer repair when the engine does not work. The engine problem could be far more expensive to solve so surely it would make sense to solve that first?

Mateusz.

Does that happen with both keys or only one of them?
