I had a full service done on the s3 about a month ago. Since then every so often the oil light will come on, on the screen. It only happens when the engine is really hot and if I've been driving in really hard or taking corners hard etc. I asked a decent car garage to check it out and they couldnt find anything wrong with it. Yesterday the same thing happened again after the driving hard around a bendy road. But after the oil light came on the engine started making a racket. It's rattling really loudly and idling really badly etc. I didnt want to drive home like it so I left it at the garage near by. Does anybody have any idea whether my engine needs replacing or what it could be? A bit tuned so maybe under strain? The oil level has always been fine aswel. Steve
