Moin moin, wanted to chisel to the coast over Whitsun, but it was not quite as loose then After about 150km the lamp started to flicker, then to flash in about 10 seconds distance to then permanently light up. Stopped and oil level controlled, but absolutely no loss recognizable. So I hoped that it was only the oil pressure switch and half the power went ahead. From the AB down, at traffic lights ran and the lamp goes off. Return the same game, light times on, sometimes off, sometimes on flickering. In my opinion, there were no abnormal noises. Now I have made up my mind here and think, oil pressure switch, oil sieve or oil pump as a source of error are most likely. Did oil fill up before the ride, rather than too little, can it be a problem? But as I said, if only minimally too much, the turbo is not open and there was no smoke cloud from the exhaust. My question: How do I go before the oil check?
