PM your email address and VIN, sounds like the dealer needs to replace the intake camshafts and adjusters, and I will send a copy of the DTB P-B-05.20/20a DEC07 to present to the SA. Warranty covers the repair with no “special” authorization from MBUSA other than normal warranty approval for a known problem specifically addressed by bulletin. With your VIN I can verify your vehicle is included since the repair applies up to engine #60 001177. In addition, your VIN allows me to send a copy of your MB vehicle datacard listing option & paint codes, transmission and engine numbers, production date, etc. for future reference.

I had a copy of the M156 bulletins and the engineers told me my Vin# didnt apply and there were only a small numbers of cars affected by the camshaft problem. I dont know how much of that was accurate but there were stern on what they told me. My question is why are theses parts failing?

That engine sounds like a time bomb. I remember other engines that had that rapping noise, but that was 40 years ago and the valve covers were off.

The regional MBUSA person can tell you how many complaints and fixes they have of this specific issue. All of their shop work is transmitted to MB on a regular basis and they can track problems well before it becomes public knowledge.

In addition to checking the TSB's & such, I would get an oil analysis done to see if you have excessive wear metals in your oil, which could help indicate or diagnose the problem. If excessive wear metals are present, you can look at the type of metal to determine where they came from. If the wear metals are within typical limits, then it's just a minor annoyance.

BTW, not to scare you, but this is similar to the sound my C55 made when one of the pistons was wearing itself out & my dealer told me to run some fuel system cleaner though it and that it was fine! The dealer gave up helping me & I dumped the car on something better. Some of these dealers are really lame & just don't want to diagnose anything, especially if you have changed or modded anything.

I can't believe I'm actually looking at an E63 now for another driver... I should just go back to the Lexus dealer & get the IS-F... I must be crazy for looking at anothe Merc. with all the quality problems I've had.

I had a friend have his engine replaced and the sound was still there. Even my SL63 has it. The AMG tech that flew out to replace the engine said it was the bucket taps that are in the new 6.2 liter motor. The sound is there, but sometimes its more evident than other times.

The TSB was issued thereafter the replacement of his engine in the CLS63.

Thats what I thought it is - until oil is up to temp and pressure they will rattle around a bit - but by slapping around they will wear them down more and they will need to be replaced sooner. Could also be the variable valve timing...

Either way its not good... wierd how they try to avoid this when the cost down the road could be substantially more.

Listened to the you tube clip, man that is a loud tapping noise. Can't see how it is normal. Mine does not have that.
I drive my car everyday. MB seems to be tightening its' purse with warranty problems.

You guys dont even know how bad Mercedes avoids stuff like this, problem is not normal and now that all 63 owners rack on miles the issues are widespread.

car is the biggest POS I hate it since day 1 and having Mercedes as your support makes it even worse.

Yesterday my car had the knock very bad in the morning so i let it warm up and was heading into NYC when it got louder and the entire driveline EMITTED A DRONE caused the car to tremble at 50mph I slowed to 35 it was that bad and almost got into a very bad rear end collision. No matter what throttle input it felt like the entire driveline was loose scared the crap out of my wife and I. Roadside took the car back to the house, grabbed my other car and was off. I am never driving the E63 again until it goes back. SOMETHING INSIDE THE ENGINE CAUSED THIS, SO PLEASE TAKE IT SERIOUSLY

My ML63 makes that noise after it's been sat for a week or more, but after the engine warms up (80 degrees +), it goes away, and never returns for the remaining day of driving. Same as the C63 and CLK BS. I wouldn't worry about it, you are driving a high performance piece with a "race" motor, live with it.

i have the same problem, i left my car sitting for a week and the exact same noise came from mine, i heard from some people that the intake manifold needs to be replaced because it is cracked check with the dealer ship on that one

Interesting.
I will ask him. Did your dealer replace the intake manifold?
My SA says it is normal.
The noise is gone for now.
Thank you very much for new information.
