The warning beeper pretty much drowns out everything else, but I still think the cam advance mechanism is the culprit. MB issued a Technical Bulletin, P-B-05.20/13a, a few years ago which describes the problem you have. Before you go this route though, you might want to try removing the Poly V-belt and see if the problem goes away. The alternator on your car has an internal inertia clutch, which reduces the engine load during cranking. I've seen a few of these make noise over the years. It's rare, but it's worth eliminating this possibility before you spend anymore time and money.
