Hello Community, I stayed on the weekend with my Volvo XC60. The following seems to be the problem: The ADAC Master pulled a piece of plastic belt out of the timing belt box, which is not of the timing belt. According to his statement, the timing belt is still moving, but the engine no longer jumps. I had the last timing belt change carried out in May/June 2016 at a mileage of 355 TKM; current mileage is 375 TKM. Can tell me jmd. What kind of plastic part this is and why the engine may not start. Greetings Daniel
