'Engine oil pressure' warning light on 2004 Audi S4
Hi, I recently bought a 2004 Audi S4 in immaculate condition and full Audi service history from a reputable dealer. 1 day into ownership, and after having driven 30 miles a red warning light 'engine oil pressure' came up :(- I checked the engine oil level and it was fine - car is in garage now and they suspect it might be a faulty sensor - but should I be worried about the health of the engine? What is the likely cause? Sensor fault? Any expereicnes with this sort of message?
