    Anyone else having belt issues with their 5.5L BiTurbo?

    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?

    Your the first person I'm hearing of having this issue and to a severe degree.

    MB told the dealer to replace the alternator. Apparently, there's a special one way pulley on it and they think that maybe the issue.

    On a side note, they gave me a 2014 CLS550 to drive around. What a freakin' great car!! Thing is just as fast as my S63. That's the car I really wanted but sadly it only seat 4 and I've got a wife and 3 kids. Click here to enlarge

    Well the CLS is a bit lighter but the M278 is nowhere near as strong as the M157.

    Not that I've heard any belt issues on the M278/M157. The best suggestion it's try the MB authorized dealer or 3rd party MB shops. Get a few master tech's to inspect issue, since not all tech's have same level of understanding. The forum it's not a good place to get an straight answer, since you will get many opinions of people without even looking at the vehicle IMO.

    Example: Engine belt could be getting chewed up by squirrels.. kind of answers. j/k
