I've drained 1 litter, now the level is at the maximum. Still get the OELMANGEL text from time to time, absolutely no dents on the oil pan, everything is perfect, the car was straight (or leveled,I'm not shure about the word
) while draining, I've no idea what to do. I'll take some pictures of the engine and will post them for you to see the engine, the oil pan, the dipstick, anything possible. I'll try to take the pictures tomorrow. Thanks a lot for your help.
