Hello! 3 days ago I bought an Audi 100 Avant C4 2.8E quattro automatic! and yesterday I drive 2 kilometers, and when I stayed at a cross and drove uphill he had a very bad performance, the further I drove the worse it got! so I thought, quickly back home again! habs just managed to get into the garage! since the condition has deteriorated very much! I was immediately aware that the v6 fell a few cylinders! so I shouted joy the pain service! we started to check the ignition, but found no engraved problem, possibly with one of the 2 not working cylinders! we dressed up afterwards all the spark plug pictures, a cylinder row had brown to white color, but with the right cylinder row this was only one of the cases! 2 candles was black and oily, but no petrol smell can be understood, rather after burned oil smells that! so we clearly had the problem to lie with the two cylinders! u And the pine helper concluded that these 2 cylinders are damaged (klobenringe, oil stripping ring,…) which is not clear to me, why is there no smell of gasoline in the 2 cylinders? is it not due to the cylinders but to the injection? I ask for your help to prepare my device for the next snowfall! Best regards Thomas
