Hello I’m new here, I bought an Audi A3 8L bj 2002 from a dealer 3 weeks ago, and now I have a problem and it has various defects e.g. – cool temperature sensor defective – ABS defective – engine does not get enough air (- Landesone or throttle valve maybe broken) (- cold running regulator also maybe broken) My question is now, can I withdraw from the purchase contract? Does this already apply to the significant defects or to the insignificant defects? Thanks already in the V oraus, Kind regards Technology456
