Please let us know the outcome.

I am confused. Did this noise appear before or after the pulley was replaced?

Quite possibly. If the car had adjusted itself to charge a low capacity battery then it seems to me that it will not charge a high capacity battery adequately. That's a bit speculative so I suggest you get some certainty at a dealer (Audi or independant) that can advise and code.

Carl. I can't answer your question, but I do suggest you flush the coolant galleries and radiator with a fair bit of pressure. Mains water pressure if that is high would be a good way. To have casting sand still in the block eleven years after manufacture is extraordinary so you need to be absolutely certain it is all removed before fitting another new pump.

Is the ACC sensor in the front bumper? If so, maybe it was disturbed or damaged during bumper removal.

My A3 2007 needed coding so I assume yours does as well. However I would expect a lack of coding to over charge the new battery not under charge it, so it's likely you still have a drain.

That surprises me Steve. Thanks for the information.

For the fan to run continuously the temperature sensor must be faulty.

Are VW electrics so different from Audi? I had assumed that both being part of VAG would mean almost identical electrical systems.

Have you read the entire thread? There is a lot of useful information within.

Skye to Inverness is a hell of a long journey. Have you looked for a mobile mechanic who might be able to come to you to do the job? I would not take Audi's word that such people don't exist. After all Audi has a vested interest in the matter.

David. Do you agree that your picture shows the fuel guage, and if so, how about showing us a picture of the aircon warning?

Good day Paul. Given that you don't want to dismantle the car yourself, the only alternative I know of are car breakers who will offer only a notional scrap value. The price offered for the car may seem derisory when compared to the value of the individual parts of it they will undoubtedly sell, but you have to bear in mind the cost of transporting, dismantling, and storing the car.

I am not surprised Tony after all the trouble the Audi has given you.

It's going to be nearly impossible to diagnose without hearing the noise. Is there any chance you can make a good audio recording? Note that most phone recordings sent to the forum have background noise drowning out the noise in question.

For anybody prepared to accept that car technology has changed over the last three decades, here is an explanation of battery coding: https://www.youtube.com/watch?v=TFK0JPs6aO0

Is that green warning light for aircon? It looks to me like a fuel filler nozzle indicating low fuel.

Happy wife, happy life.

"oil housing section" is not a term I recognise. Can you elaborate please? What specifically is written on the invoice?

As you wish Dave. I'll not waste any more of my time trying to convince you otherwise.

It has nothing to with theft prevention, and everything to do with ensuring the battery is charged correctly to avoid damage.

A photo might help Graham, because I have no idea what a door blade might be.

Good morning Michael. We as a group do not have access to Audi data because the forum is not affiliated in any way to Audi. Individual members might be able help, but it's unlikely so don't hold your breath on that score. "Audi are being difficult to deal with" has a familiar ring on the forum. Some of us would regard that as an understatement.

Please do.

I am in Kent, so no I can't help on that score.
