Purchased very clean, 1-owner 1999 C230K six months ago with 53,000 miles. After four months, the Kompressor stopped engaging. What was first diagnosed as an actuator problem now looks like a broken kompressor seal. Local dealer says total unit need replacement ($2000). Am I just unlucky or what? Dealer says only seen 3 such failures over the years with no consistent root cause. Questions: anyone with similar experience? Are there any aftermarket or remanufactured units available on the market? Do I have any other options but replacement? Thanks from new site member.
