Hiho, was just with the friendly because of the problem standing in the subject. The mean, the bender has a crack and has to be changed. I could not see the crack. Now I do not know if I can believe the friendly one. Because in the forum here there are some entries, that maybe only the seal is defective or the screws/bolts,… should be replaced or simply tightened, then sparks again. By the way, at 180tkm. The fact is that after about 2 minutes the fluttering tractor noise is gone. Can this circumstance be at all, if the crack itself has a crack? Or should I have the bolts checked by another workshop before? thx for info. Greetings Playa
