Good evening ! My 55 ́er weakens something, I would need help from someone who has a star diagnosis and could read something out to me … It is probably about the pressure of the tandem pump that would have to be billed again (according to the workshop) Got this 3 weeks ago and about 400 km new + flushing and etc … Then after 16 days of service and short drive (about 3 km) the ABC went to the message: ABC workshop, 1 minute later in ROT: ABC Careful driving ! 30 seconds later came a la ut knocking sound from the front left … Beautiful crap Is there someone near who owns an SD, or someone who knows you :-)) who has it and could make me a contact ? Thanks for reading and a helpful tip
