Start-up Noise on E63
I did a search and discovered that there have been some discussions about start up noise on the E55s. My E63 has 400 miles on it. When I start it up (cold) I hear a thonk, thonk, thonk--kind of like the heat risers on older American cars.
It is not loud like a rod knocking--could be piston slap--goes away after the car warms up. Is there a consensus explanation for this phenomenon?
I do tend to be sensitive to automobile noises, especially when the car is new. The transmission on the E63 also seems to whine a bit (buzz, whine combo sound).
Anyway, have others experienced the start up sound on their E63s?

Cosmic,
I have five hundred miles on my car and no clunks in the morning here. But it's been very warm here in Phoenix. I do hear the transmission noise that your talken about it does go away after a few hundred feet.

Where do you find these bulletins. MB sure doesn't offer up any. In fact, if it weren't for this forum, we would never find any help with our service needs.

A $95,000 car with a hand-built motor that makes a strange noise? If somebody at the dealership says it is a "characteristic of the motor," I'm going to go postal.
My Z06 was hand-built American and it didn't make any strange noises.

Does anyone have an official diagnosis? If there is a service bulletin on the problem, then there must be some idea what is causing the noise.

I am a dealership technician. Sometimes the response of (unable to duplicate) happens because it was not duplicated. Until a technician hears the noise it is impossible to fix it. Now that there is a bulletin regarding this particular startup noise it will be possible for a technician to perform a fix to a problem that they were not necessarily able to duplicate. These engines are VERY new, and there are not that many of them. It takes time for Mercedes/AMG to hear from the dealers and have enough dealers duplicate the problem to broadcast a fix for the problem.
The fix involves replacing a camshaft adjuster to an updated part that will resolve the problem.

Please take some of what we say with the grain of salt that is needed. Sometimes our frustrations are due to a few bad apples not doing their due diligence. Keep in mind that Cosmic just had his car in and the DTB has been out, yet he got no fix. I can name a half a dozen techs / SAs that would have done the background to find out, rather than the bland response he got. I am sure you are one of them.
In this case, where there is a "fix" and he clearly is not just saying stuff (since he didn't even know about it), how should Cosmic enlighten his dealership onto the fix? Is there a way for him to get a DTB reference number or something to provide?

Glad to have you onboard along with the few other techs that frequent the site.

This type of problem corroborates the perspective that many people have about buying new offerings from the auto manufacturers. This means I have to leave my car at the dealership for at least a couple of days. I bought the car 90 miles away (still the closest, best dealer), so it involves a minimum of 6-8 hours of driving to get the repairs, etc.
I am thankful that there are some Mercedes Tech folks who frequent the forum, because it allows us to more effectively participate with the dealer in diagnosing the problem. Thank you MBTECH2003 and Jangy for helping me with this one.
I only have 400 miles on the car, and I would like to drive it for awhile before taking it back to the dealer. Will it cause any damage or cause any ancillary problems if I drive it? I would like to get 1000-1200 miles on it so I can take it in for the oil change and initial inspection at the same time.
Thanks for the help guys.

I am surprised manufacturers don't have a forum like this where they can address complaints first hand... I guess they dont like the dirty laundy being aired often.
It would save all concerned so much time and money...

You wont see any additonal damage done to the engine by waiting for your first visit. When you return, mention that you were aware of a buliten describing this particular symptom.
Hint: dont mention that you read it on a forum... fair or not 9 times out of 10 it will take the credibility the advisor puts in you into the hole.

Just to bring more information to this issue, the shop foreman at my dealership thinks it is the oil pump. Several S Class cars on the lot make the same noise.
He says MB is aware of the noise, but when and if they will issue a fix is uncertain.

Does the noise sound like a "tick" or "clicking" noise on cold idle? My E63 only has 100 miles on it but I notice this noise every start up. Is this the same thing?
