AUDI ALL THE WAY I HAD THEM JAP THINGS NEED EVER LASTING MONEY KEEP THEM GOING KEV

How did you resolve the problem? Were you able to save the old battery?

This is my second post as a Newby. My stolen RS6 emergency black plastic key was found by Mr Keval Morarjee and handed into the dealership where I recently bought my car. I now have this key in my possession and would like to thank Mr Morarjee for his help. Regards, Robin

Just goes to show there are still some good people in the world

It's not unheard of. But think it depends on the map, engine etc.

I'll second a dyno and custom map. Probably also a good idea to use someone who knows the car so that the necessary components can be checked for good health before putting extra stress on them.

For best results I'd get a tuner with a Dyno. As they'll tailor the map to the car.

SOLVED!! Was the thermostat in the end, which some reffer to as coolant actuator. Latter is probably more accurate since it's an electronic motor driven device which performs the same function as a thermostat. It looks as though the thermostat housing had failed, and not at the classic location of where the unit attaches to the block either, but somewhere right in the middle. The garage has let me keep the defective part so i'll be ken to investigate the cause more closely. Not just ouf of curiosity but also to provide feedback to audi themselves. A £300 pound part, in my view should not fail on a 6 year old car. Especially when any typical thermostat would cost less than £40 and probably be easily fitted by the owner and certainly not a multiple hour job for garage like this was. I also believe that it's this leak which must have cause some kind of oxidation of the coolant which then also cause a secondary water pump motor to go - which shut off the stop/start function, and the level sensor in the coolant reservoir. All in all a very expensive, time consuming and frustrating few months. I'll post some pictures up soon of the faulty part. Be interesting to see what anyone else thinks

Hi Chris, Brief update. I'd bought a replacement thermostat but still wasn't 100% sure where it goes. The pictures on the sites that sell them show an arrow pointing to the collant actuator / water pump housing. I'd asked the supplier via email where its located on the car and they replied saying they weren't allowed to tell me - wtf? Out of curiosity i'd asked a local garage how much to replace the thermostat and they wanted £750 with no guarantee it would fix the issue. I was all set to remove the entire water pump and coolant actuator but in the end i thought i should probably get a second opinion. So yesterday i took it to another 'Audi specialist', in Nottingham. They called me back to say its the coolant reservoir. I was surprised and asked could that really cause the temp to read funny, they believed it could. £70 replace and fit + £50 diagnostic I thought my luck was in. But at the back of my mind i remembered that you had also tried this approach so i wasn't overly excited. Just picked the car up, drove about 2 miles, called into a shop and when i jumped back in the engine management light back on. Car didn't reach temp driving home and scan reveals the P2556 coolant low level fault is still there. They've asked me to take it back in tomorrow. I can only assume that they didn't actually do any kind of diagnostic into the cause but simply plugged into scanner and believed what it was telling them - so much for being a 'specialist'!
