I bought them at the dealer. They usually don't have a clue on what the * they are doing over there, unless they know a part number. I will check anyhow. The old mounts (I save everyting) are so worn you can only see that there was a part number on them once. I don't know of any aftermarket MB part sellers in the Netherlands, BTW. Any other suggestions on rocking 300D's?

Thanks Mike. I guess I can start checking, now I know what to check for :) Today I noticed a small leak somewhere at the fueltank - tank is wet at the front and bottom, it is not dripping (yet). Some fuel hoses are wet too, so I'm gonna replace them all this weekend. And who knows, maybe this will solve the rocking as well. The engine is starting to idle a bit less smooth when cold, I guess this can be due to air in the fuel too (?)

For what it's worth (coming from a MBZ-newbie), I agree with Mike. Check for air leaks first. Next, I'd suspect an injector. Related question: How does the injection system on MBZ Diesels handle occasional bubbles? My diesel experience began with marine engines, which would choke and die if fed an air bubble. When that happened one had to loosen all the high-pressure lines at the injectors, crank the engine, and as each cylinder caught, tighten them again. Not much fun in the bottom of a boat rolling around in the ocean, but a great way to endear one's self to one's shipmates! Some of the newer Diesel engines that had the Bosch fuel injection pump had no problems, as did the engine on my old '79 Rabbit. How do the MBZ Diesels handle bubbles? Do they choke completely, or pass the bubbles back to the fuel tank in the return line?
