Startup Engine noise Explanation from MB

To my experience, I usually get a stuttering startup noise after the car has been turned off for a few hours then turned back on (when the weather is warm/hot). I know there are threads on this topic before, but i finally got the Dealer to reproduce it! does this sound right?

Yup! Sounds right and makes perfect sense to me, especially if your car has over 15k miles or more. Is EuroMC's your dealership? Hope it's the Germantown branch!

My 350 sometimes stands for days & the lifters do not loose prime & are silent. Noise can also be camshaft adjustors & timing chain hydraulic tensioner until oil pressure comes up. My engine is silent on all counts.

Except it's hot as hell here in Maryland where it's expected to reach 104'F ! I agree, they should not bleed-down, but you must admit, it can happen on one or two over time, especially during hellish weather. The chain tensions do as well, and can be costly to replace. Maybe it's a little of both. Either case, it's okay unless they fail to pump-up and go silent.

I must say i am jealous! =P but yeah.. i've complaint about this every time i put in my car to the Dealership, at least this time they actually reproduced it and gave me an answer.
and MD's weather is hot and humid! yeah man i only go to the Euromotors in Germantown, my SA seems to be a cool guy and i can trust him.

I have it at start up as well on my '08 C350, I was very concerned the first time I heard the " ba ba ba ba ba baa " sound, so contacted my advisor and he said what Glyn is saying, cam adjusters waiting to get pressure??? hmmmm either way, they all seem to agree it is ok.
Why does everyone seem to use "Loose" in place of "Lose" on this forum? ;-)

Because it sometimes sounds the same... Rather than saying "lose", I/we/they (hopefully not you) say "loose", then we gets all confused.
Besides the example above (i.e. then vs. than), some of the most common are:
Their/there/they're
To/Two/Too
English is a funny language.

Thanks for the info....I feel this explanation is right on. Sometimes when I start my car, I listen with my eyes closed to imagine what conditions/parts would produce the noise. This description is exactly what I've been imagining.
The confirmation is very reliving.

Of course it's not normal. The "explanation" is designed to pacify owners. Last time I looked at the fiche for the oil pump in my departed M271, I saw a checkvalve on the output whose job is to prevent drainback.
I went through the same thing with my Porsche long ago.

Look, although i know some dealers love to BS and pacify their clients, most are in the business of extracting as much cash from your wallet as possible. Therefore, if they thought it was bad, they would have made up some other BS story to make it sound much worse than it really is, with the intention of ripping off the client. So it all depends on the severity of the "noise" along with the duration before it goes silent. Hydraulic lifters have built in check valves. For all or most of them to go at once would mean either the engine was beaten to death, or way over-revved or both. So I would guess that Glyn is correct that it's the chain tensioners. That check valve I believe is located in or near the oil filter housing. If the problem persists, go back or go to another dealer and have them check out the tensioner/and check valves for proper operation.

Hi Guys,
I know this topic is a bit old, but I have serious concerns about a noise that came up few days ago. Here's a video:
Are you talking about the same sound when you have to replace this timing chain tensioner?
Also I have 1 error and I'm not sure if it's related to that noise:
0060 Continuous Stored camshaft adjustment (RIGHT) : Incorrect position of the exhaust camshaft (P0015)
I'm concerned it could the balance shaft although I don't see the check engine light. The car is CLS 350 MY2005.
Thanks!

The air pump is a pollution control device. It only run when the engine is cold to pump fresh air into the exhaust until the catalytic converters heat up.
About the error from my first post - it's the cam magnet.
P.S. Many many thanks to Rodney again
