I have a 95 E320 with 157k miles on it that will make a series of noises before it is warmed up. Upon initial start you can hear the oil pump wine for a couple of minutes (common to the 104 engines), also it will have a slight diesel sound if I drive it right after starting it up cold.

As far as the clatter sound goes, it will do that too on occasion, I found out it is a lifter leaking down overnight. That sound would last for quite a while after initial startup and eventually go away after it was fully warm.

I switched to Mobil 1 0W-40 several weeks ago and it seems to have taken care of my lifter noise upon startup.

Do you think it sounds like a lifter? Very possible depending upon what weight of oil your using and the total miles.
