Mark. You could waste huge amounts of money fitting new parts at random in the hope it will solve your problem. You have already bought coil packs, a carbon clean, and a mass flow sensor to no avail. How much more money and time are you prepared to throw away? The key to an economical repair is diagnosis on a VCDS or similar quality machine.

I really don't think I can help any further Steven. The only way I know to approach a problem like yours is based on logic not guesswork. Let's hope somebody else will chip in with ideas for you.

Steve. It's been years, well decades actually, since I took a crankshaft out so I have no idea about the specific tasks involved in yours. However the major obstacle I found was disconnecting the engine from the transmission. In my case, involving an in line engine and rear wheel drive, that entailed removing the propshaft, the gearbox, the clutch, and the flywheel. The lesser obstacles were at the front of the engine and entailed removing the crankshaft pulley & belt, the timing cover, and the timing chain, all of which necessitated removal of the radiator first. Even though the layout of your engine bay will be greatly different from my old Fords and Austins, the same principles will apply. It was a lot of work, much of it under the car. I suggest you hire an engine crane to make the work easier and quicker. I could not afford such things in my early years of motoring.

It sounds like the instrument cluster is faulty, a not uncommon problem. It can be repaired by a few companies if you remove it from the car and post it to them, or you can pay a great deal more at Audi.

Remapping has made it much harder to diagnose the faults. If a proper diagnosis does not lead to a fix, all I can suggest is to restore the original map and hope for the best.

Has the car been modified in any way, or remapped? I suggest you get diagnostic scan on a professional machine, the cheap DIY readers are inadequate for a thorough anaysis.

You won't get a reply from Fubar as he ended his membership of the forum.

I interpret those figures as £0.27 per mile, which is not surprising considering the cost of electricity at most public rapid charge points. It was commonly £0.83 per kWh the last time I looked. The only way to fuel electric cars at a lower cost per mile than diesel or petrol is to charge at home, especially if you can get cheap overnight rates of £0.15 per kWh or less.

This is the one I mean Manjinder. https://www.audiownersclub.com/forums/forum/142-audi-a3-8y-forum/

That nobody has replied does not mean nobody has done the job. That is an unwarranted assumption.

I've never heard of it, so I guess it is a uniquely American standard. Are you aware this a European, principally British, forum?

Glad to read it.

That's very good news.

Was the reply any use to you Charles? I know you have seen it.

Were the above comments of any use to you Allan? I know you have seen them.

A wise decision, which two of us have previously recommended, and all the more worthwhile in view of your latest revelation of a damaged plug.

Console yourself with the thought that the fix was cheap.

Anybody suffering from recalcitrant dealers in this matter should note Bartosz's comments and show them to their dealer. The more evidence of the fault being corrected under warranty, the more pressure can be applied to Audi and its dealers.

Ensure you code it to the car or it will fail again.

Thanks for your response Christine. It's rare for any gratitude to be shown so I am sure Steve will be pleased.

You have not mentioned the battery yet. Be aware that a defective battery can cause false error codes and warning lights. It can also cause the engine to enter limp mode, which sounds very much like your symptoms. As a first step I recommend you get the battery tested on a professional deep discharge machine that will detect internal faults and its state of health. Only once you have a good battery that is also coded to the car will any error codes become meaningful.

If the instrument cluster proves to be faulty there a few companies who can repair it for much less cost than Audi.

So the drinks are on you Kev?
