I have a 60 plate Audi A3 1.8 Tfsi, I’ve had it around 4 months now. The engine management light has been on since I bought it, it’s had a full service once I got it with the correct oil and filters etc. The engine management light is still on. The car is a bit lumpy when first started but runs absolutely fine after 30 seconds. The only real issue I can see is I’m having to put 2 ltrs of oil in every 300 miles!! That can’t be normal right? Any suggestions as what the problem might be or how to solve it? Reading these posts, I contacted my local Audi dealer and they did a quick reg check and said there were no known faults or recalls on this car. What should be my next step? I can’t afford to do major work on the car as it’s only worth 3-4K did anyone have any luck down the solicitors route with the no win no fee thing? thanks
