Hi Gareth
The oil lights came on straight away. The dealership retained the car for a week to try and sort the problem but gave up. I’ve not added any oil as If the car has the correct level of oil I will overfill it. The car is under warranty so it is Audi’s problem. I have in fact just heard the dealer is taking the car in, drain the engine to make sure that the correct level of oil is in there. Quite why they didn’t go this in the first place is beyond me. The car was fine before they drained the oil, what can possibly go wrong. Chris
