Anyone else have belt issues on a M157 engine?
I'm about to drop off my S63 for a third time now and have a new belt put on the engine. This will be the third time in 9K miles they've fixed this. First time they replaced a pulley saying it had a broken rib on it. Second time they opened up a case with AMG on it. Now again, belt is shredded and squealing. This is starting to get annoying. Am I the only one with this issue?

That is strange and you may have a few bad bearings in one of your 5 belt idlers. One idler wobbles and then belt jumps onto a rib of anoither anf brakes the rib. Then tech, thinks that is the issues, when in fact it is another idler culprit.
