Re: ML320 Harmonic Balancer

Most of the newer MB engines have problems with the balancer. Most of the MLs have problems with the window switches and low range switches......

As stated previously, I would demand the balancer and upper oil pan if needed be replaced at their cost not yours..until they develop a balancer that wont break apart.

Do you have an extended warrantee?

Yes, and sometimes using the term "goodwill" will get results as well. If the dealer is being hesitant, involved the MB zone rep.

No, I didn't get the extended warranty and I didn't think I needed one because of their reputation. This is my first Mercedes, and also my first car that's given me any kind of problem. I've owned many cars, American, Japanese and German, but the ML320 is by far the worst car I've ever owned.

With the help of this group, I've found a lot of information about the harmonic balancer problem. The dealer is reluctant to admit their is a problem, and the service manager said

These cars, regardless of class, an extended warranty is the way to go. They're super expensive to repair, a good 3rd party german car mechanic notwithstanding.

Good luck.

I worked on a CLK320 in today with the same fault, 68k miles '99 car. Its chewed up the timing case and also taken out the poly belt and tensioner. We quoted around £1500 + vat for the total repair, and Mercedes are paying half under goodwill.

Parts were about £300, 13 hours labour. Looks like a bit of a bitch to change the timing case, I'll soon find out....
