Rattle on Startup
Hey guys - I have a rattle/vibration sound occurring only on startup. It's starting to occur more often and of course the dealer has told me they can't hear it. It's actually quite loud and sounds like its coming from the exhaust somewhere near the front of the car. Almost sounds like something is loose. Anyone else experience this issue?
Thanks

I get this also. Mine is intermittent. I don't know if we are talking about the same sound but mine sounds like the timing chain is dragging on something at initial fire up.

Mine honestly sounds like an exhaust hangar is loose or something. Only occurs when i initially turn the car on though - if it was an exhaust hangar i would imagine i could hear it through certain power bands, no?

I did a lot of digging around on this and say your threads. I called both local dealers and they said they've never heard of this causing a rattle. I am going to take it in but already feel like it will be a frustrating experience and they will say they don't hear it.

I've had rattles and all 4 replaced (one at a time as the rattles happened). On a side note, I've asked my MB rep and he said it doesn't cause any damage anyway. Not sure if his word is gospel, but he is pretty forthcoming and knowledgable, plus I asked him when my car was out of warranty.

Same sound I have had for the past 16 months been to the dealer multiple times for it it's the cam adjusters I had them replaced still didn't fix it car drives fantastic I'm not paying attention any longer good luck having the dealer fix it basically told me it's normal it's not but not hurting anything right now I'm keeping my ears closed on start up lol was told my valve train looks great so appears to not be hurting anything in 16 months or performance either just noisy o well if they fix it let me know please
I will let you know if they do anything but I'm expecting a lot of pushback.

Don’t call the dealerships as they would have never heard of any issues or problems whatsoever with any of their cars in since forever.

You know, I have thought about doing this myself because I get the cam adjuster rattle every now and then on cold start
Update:
Just looked and Walmart doesn't carry 5w40
They always have 0w40 on sale so I guess I am sticking with that

Just an option and I have to admit I enjoy FCP's warranty that makes an oil change cost about $20 now.

I’v had my Cam adjusters changed as told by a specialized mercedes mechanic. Once changed he told me the car is perfect. Took it and on the first startup the sound is back. Had the oil changed already and using 5w40. Any other idea what could be causing this otherwise?
another question would be about another sound i have. It is similar to the video below.. anyone knows what is the reason behind it?
Thanks in advance!
