Hi, I encountered a strange problem on my drive home from work this evening. Driving steadily at 30mph I notice a big drop in power and my engine warning light comes on. I pull over and refer to the manual. After following the advice of starting the engine over at 30 second and intervals, the warning is still on but I manage to drive the remaining 3 miles home. I ring my local dealer who can't guarantee me a booking any time soon but advise that check the oil. I topped up a couple of months ago so I doubted it would be low oil but I check anyway. The engine cover from the cap over half the engine to the right looks wet with oil! The cap is sealed. No obvious leaks. What on earth is going on? Any advice would be most welcome. I'm running a 59 plate I-CDTI with 65k on the clock with full service history.
