Hello, I urgently need help. I bought a used Combo C Tour 1.4 twinport, 9/2005, 138000 km, and this one has the following problems: – It consumes far more than 1 liter of oil at 1000 km – The oil pressure lamp lights up again and again in idle mode, even with newly filled oil, then only after about 25-30 km – On the level: 5.Gang Tempo 110 When I then give full throttle, it takes 30 sec to get to 120. After 3-4 minutes it is possible to go to 135, then it is closed. I can also speed up to 135, then goes faster, but then the 5th brings nothing more. What can that be, that is not normal, right? Is the engine over? Please help me so that I can talk better with the dealer, negotiate. Thanks cigar box
