just joined in order to check whether or not I'm getting the run around from the local Mercedes"expert" - less than a month ago they repaired a broken vacuum line, when the check engine light was reported to them during the 150,000 mile service. Two weeks later she began to stall and we barely got her back there. reportedly the crankcase ventillation leaked "somehow" and "stopped up", causing oil to shut down the air mass meter - this will have to be replaced (I'm glad I see the $300 above from last year) @about $388 (plus replacing a hose.

Anybody out there have experience with these guys? Did they screw up the crankcase during service last month? Or simply time for the crankcase to cause this? Any opinions?

Thanks
