I guess what you are feeling is crystallised Adblue, which is a common problem in such systems, and presumably why you want to drain the tank.

In theory Adblue, which is principally urea, is very soluble in water so it should be possible to flush the crystals out with a stream of cold water. However I have never had anything to do with Adblue in my car so I do not know how practical the idea would be.

Check the earthing of the lamp unit.

Especially when it's laced with sarcasm.

Great Forum this.

I was always under the impression that forums are to help each other 53 views but not one reply!

Time you learnt some patience. It has been less than a day since you posed the question. If you get no reply after three or four days it would reasonable to assume none will be forthcoming.

53 views does not equate to 53 people able and willing to help.

1. Rear RH side door - Door does not seem to "latch" fully when closed and soft close does not engage (Door will ONLY close fully with some force, but will then open slightly ajar when driving as if it is not fully shut). Only cure is to close the door fully, lock and then leave for a few hours before it will then stay shut while travelling .

Has the door been removed or damaged? If so, it would be worth looking for some misalignment of the hinges or lock hasp. If that aspect is fine then I suspect the lock inside the door is defective.

How hot is hot? Yes all discs will become warm or even hot if used a lot, but being too hot to touch is too vague an indication of temperature to say whether something is wrong. However you said you can smell the brakes so I suggest that indicates excessive rubbing.

All work done by Audi dealers will have been recorded on a central database, so even if you bought the car from one garage and serviced it at another any modification should have been recorded. Logically then, either this special chip does not exist and the garage is mistaken, or the chip does exist and has been fitted by a non Audi garage.

Brake fluid? Clutch fluid? Coolant? Screenwash fluid?

I am not familiar with the A6 so I can not say whether hot discs are normal, but I doubt it.

As for the deformed tyre, who can say what the cause was after five months of use? It might have been poorly made or it might the result of operating conditions. It rarely pays to buy cheap tyres is all I'll add.

Thanks for the update. The spare wheel has solved the noise, but can not explain the hot disc. Is the opposite side just as hot?

Looks like you need an electrician.

Fair enough, then it must be something else unless damaged by draining it flat.

I have never known tyres to perish as a result of ageing until well over ten years old. Four years at 10000 miles per year is going to wear them out long before the rubber degrades.

Forget the voltage of the battery. The right voltage and the ability to start the engine do not mean it is in good condition. Internal faults can interfere with the car's electronics and cause false warning messages and symptoms such as limp mode, loss of radio presets, loss of cruise control etc. So I ask again how old is the battery?

Glad to hear a new thermostat resolved the problem. A shame you were talked into a new water pump before investigating the simplest solution.

I doubt it was the jump start that caused the problem. My guesses are:

[1] the head unit you removed was integral to the ECU. Can you refit it to test?

[2] the 12 volt battery is dying. How old is it?

Have you seen this topic from just a few days ago?

Failure of the instrument cluster is well known. Fortunately they can be repaired by several companies for a few hundred pounds, which is a fraction of the price of a new cluster from Audi. As the RAC said, you need to remove the cluster and post it to the company for repair, and then refit it on return. ECU Testing is one such company which has a good reputation on this forum.

While I am pleased to hear Stansted Audi are accepting responsibility, it does their reputation no good at all to have sold the car in that condition. It discredits the whole Approved Audi scheme.

Ah, so you did. Apologies.

However, I still had to pay an extra £400 for the unnecessary wiring work.

That sounds about normal for a couple of hours work.

A new transmission on a six year old car is surprising. How many miles has it done?

It might help if you told folk what PCD and number of holes you are looking for.

Have some patience Guy. Your question was only posted 24 hours ago. If there is no response in a week it's safe to assume that nobody here knows or is willing to respond.

Considering the potential for damage to delicate electronics by reversing the polarity it will be a miracle if the car can be restored without help from an auto electrician.
