Hello, our SLK 200K with the M271 engine (80,000 km) rattles while starting for a few seconds. This is actually so since new purchase, but so far the flap was not scary. It probably comes from the fact that the oil runs out of the hydro-stumps during service life and has to be pressed back in when restarting. Since recently the flap has become very loud with longer service lifes (2-3 days), it now sounds really unhealthy and scary. Can you fix something here before something collapses in the cylinder head? Thanks for tips. ciao olderich
