Name that NOISE on 2005 c320!
We just bought 2005 C320 4matic with 68K miles and have this slight knocking sound that reminds me of a pulley wobble.
It comes from the belt area where power steering pump and belt tensioner pulley are. It is more pronouonced when car is cold and in drive while stopped.
I made a video of it this morning before I took it in to MB for second time. First time they changed pulley on the AC compressor but that didn't took care of it..
Has anyone had similar problem?
I am thinking it could be belt tensioner pulley but I am not sure.
Here is the video/sound clip: http://www.vimeo.com/7662672

Mine was making a similar noise + a "belt wobble" noise for about 1 - 2 seconds when first started. They replaced a ton of parts before finally swapping out the PS pump which seems to have fixed it.

Damn M112 engines. But yeah that noise is hard for anyone to point out right off the bat. It would be a trial and error battle just to find out the source. If under warranty take it in and let the stealership deal with it.

Too many reliability issues / runs too rough.

Yeah - my friend in Malaysia now has 760,000 Km on an M112 engined C240 in taxi service & no major repair & our office taxi here in Cape Town - E240 has gone over the 600,000 Km mark trouble free. The M112 engine & drivetrain are bullet proof.

The M271 in the 2005 cars seems pretty reliable. I'm not having any engine issues and neither is scottisha who just posted the photo of his 2005 C230 with 199k miles. It's not V6 smooth but it's pretty good for a four-cylinder!
