What has the screen wash got to do with the heater fan?

He has not returned to the forum since 24th February.

Your choices are: an Audi main dealer, an independant VAG specialist, or a gearbox specialist. I generally prefer the second option.

Automatic gearboxes have clutches nowadays and one of them, (it will have two,) is possibly slipping. Get it tested on a decent code reader such as VCDS for more insight.

Perhaps there is a free car attached.

The same problem gets the same advice as above: get the steering and suspension examined.

Boot battery? Are you implying this is a hybrid drive system which also has a 48 volt starter/generator and battery? If that's the case all bets are off. Please confirm your power unit.

That is often caused by rust on the discs, especially if you washed the car with a hose before parking it. If so, firm application of the brakes a few times should clear it. If that does not solve the noise it would be worth inspecting the brake calipers and pads for seizure.

Lyn. I recall a similar report a couple of years ago, but do not have time to find it. You may be able to by searching the forums.

I think it means you have to pay Audi a subscription for access to the map data. It's a nasty trick by car makers to screw more cash from the customer.

Not all models had the silica bag, but doesn't mean the matrix is not blocked by something else such as sediment or an air lock. Nor have we eliminated the flap motors in the air ducts, which as Richard mentioned, are best test tested with a decent code reader.

Not personally as I don't have one, but as mentioned earlier, VCDS appears to be the most versatile.

A decent code reader such as VCDS will be able to read historical codes that are no longer present.

Dave. If all the air vents blow cold I'd agree it's likely the matrix; however if some vents blow cold while others blow hot it's more probable that some of the flap motors in the air ducts are faulty.

That's good to know Sarah. I knew ECU testing have a good reputation regarding repair of instruments, but was nor aware of their skills with brake servos.

No matter how expensive the genuine Audi clutch, it will be cheaper than replacing a damaged gearbox.

How about revealing some details Peter. Diesel or petrol? Size? Injected or carburetted? Cold ot hot?

Then it undoubtedly needs to be renewed. Ensure you get the new battery coded to the car.

How about getting the parts wrapped instead of painted? If you don't like the result it can be removed or replaced with a different colour. As far as I know wrapping does not need the parts to be removed.

Steven. I have merged your two identical topics.

Can we assume it was a private seller so there is no chance of recompense?

That alone might be enough to explain the noise, in which case the wheels may well be damaged and need to be changed. Take them off and look for cracks and abrasion around the stud holes. In my view any such damage means they should be scrapped as I am unaware of a way to repair them.

Was the above information of use to you Richard? (Sorry you have had your name removed by forum software. Nothing to be done about that unfortunately.)

A common cause for that is a dying battery. How old is it?

Are there any petrol only models? Diesel could be problematic if used for just short journeys.
