cold start ups... do you have loud ticking and rattling noises from
the engine? my engine has gotten progressively louder on cold starts.
dealer tells me its normal as the car has dual overhead cams and oil hasn't reached the top yet.
makes sense, but i've never had it this loud before.

I let mine sit for 3 weeks in storage and when I started it up, it sounded like crap for the first few seconds as the oil got around. Funny thing is, I stored my Ford Lightning pickup truck for the same amount of time alot more frequently and never had any unusual noises starting it up.
I've noticed ALL the mercedes I've owned seem to sound more and more rough as they age....even the AMG's.

I have a 2007 ML350 and actually heard the same noise two days ago. I actually stopped the car to take a look under the hood. I've also been noticing that the engine makes a wining noise on normal acceleration at low speeds.
I'm guessing it's a mix of the cold temperature and the fuel management system (i.e. fuel consumption control). I can't remember if the engine sounded the same when I first bought it. Currently have 18k miles.
If it gets worse, I'll be sure to post. For now, rest assured that others hear the same noise.

I too have heard my ML350 knocking at start-up when cold. 8K miles. thought about taking in to the dealer, but reading this tread makes me think it is a by-product of this model/design.
