A possible explanation has occurred to me. A3s are prone to faults in the instrument cluster that usually result in the lights failing or flickering, and the instruments to fail. Perhaps such a cluster fault is causing the otherwise unused TPMS light to illuminate. I am no electrician so maybe I am talking nonsense, therefore I too am keen to hear the final diagnosis.

You need to consider what is essential and what is merely desirable. For example why are you considering changing the main and big end bearings? Do you have evidence of wear?

Be aware that timing belt failure, which will happen without any warning, will destroy the engine. Can you afford for that to happen? You have no choice but to repair the suspension and steering parts as they are MOT failures. The other repairs are optional at the moment.

Not sure what you mean by "mean" seal. I can not see your picture as I will not download such things from strangers. Are you sure it is oil and not brake fluid?

Alan. The question has come up here several times in the past on this forum. I seem to recall there was not an easy or cheap solution. Look through forum history for details.

Oznitas. There are several companies in Britain who can repair instrument clusters for a much lower cost than a new one. Surely there must be similar companies in Spain?

That's unfortunate, but what else can you do? I suspect the lack of speedo and dials would be an MOT failure.

And in that other thread it was pointed out that the battery needs to be brand new and coded to the car. Until that is done, all the electrical faults and error codes you are suffering are meaningless gibberish.

Ah. That was last year not a few days ago, hence my confusion.

What thread do you mean? The only one I saw was about a fuel pump.

If the car genuinely has a TPMS there must be a reset switch or menu item. Therefore either you have not found the reset, or there is no TPMS and the warning light is false.

This topic comes to mind: https://www.audiownersclub.com/forums/topic/21817-electrical-fault/ otherwise earch for "instrument panel".

Daryl. It's probably a faulty instrument cluster. If so your options are a new one from Audi or to have it repaired by one of several specialists that you can find on the internet. Search through previous queries on this forum to find others with the same problem. I seem to recall a cost of £200-250.

Alastair. I have no certain knowledge of those clips, but I don't believe Audi would add to the cost of the car by fitting them unless they were necessary. When every penny of manufacturing cost has to be justified to the bean counters the design engineers must have had a good reason to fit them. I also don't understand how the clips got into the sump. Clearly they were not fitted correctly to the rockers by whoever has had that engine apart in the past, but I don't recall a passage between head and sump large enough for the clips to fall through. Of more concern to me is the fact that the engine has been run without lubrication, a potentially destructive operation. Have you driven the car yet, and if so how does it sound and what is the oil consumption?

Well I'm damned. Does that mean the ECU adjusts the injection according the age of the injectors?

Possible culprits are injectors, mass flow meter, CPU amongst many others. I agree with Gareth that diagnosis by somebody knowledgable is better than renewing parts at random.

Still under guarantee. Thanks for letting us know.

Let me repeat what I wrote five days ago. "Be wary of any computer diagnosis if there is the slightest chance of a dodgy battery. A3s are known to suffer a variety of seemingly unrelated electronic faults and their associated "diagnoses" if the battery is at all below par."

"they charge like wounded bulls" That's a phrase I must remember. Good luck. Do let us know the outcome.

Good luck and do let us know the final result.

Thanks for the update Ricky. Here's hoping no significant damage has been done while the car was without lubrication.

No. The battery needs to be coded to the car. I don't really know what is involved to do that, but I know it needs to be done.

You could avoid time wasters by publishing your prices openly. People who advertise without prices are, for some of us, also time wasters.

The remap could undoubtedly have been the cause of the problem if it was not matched exactly to the engine, which of course the remappers are not going to admit. The only way to prove the point is to revert to standard settings. Equally it could be any of the other factors mentioned. They should all be investigated. That is going to be expensive if done by Audi; you would do better to find an independant VAG specialist. Whatever the cause, running rich will block the DPF.
