Hello in the round, the new one is here. Got a problem at least my Volvo. On Friday, the rib belt to the alternator is torn (alternatively, I think it is very brittle true). From the Bosch Car Service. Belts ordered and repaired on Monday (nightly) picked up. within 25 km the Volvo leaves and jumps no longer. Organ organ organ, but he does not want to start. Ergo called the ADAC and waited. In this hood uf and looked inside. Rib belt to jump a tooth to the side. ADAC man arrived and camshaft sensor error message. Generator too little tension. I called the factory town and the dare to go. In the factory town they searched for torn cable from the sensor and found nothing since the belt had been slightly shredded (ist) and the mechanic said that I guess the tooth strap has jumped around a tooth. Now I have the stupid feeling that the rib belt developed such a force that it came to the jump and the mechanic can’t say no and the mechanic doesn’t ask you enough.
