Whoa!!!! Don't Do Anything Until You Get A Second Opinion!!! I Had A Mercedes Dealership Tell Me That You Can Change The Sc Clutch Without Buying A Whole New Supercharger!!! To Quote The Mechanic, "changing The Sc Clutch Is Easy, I Just Pop It Off And Replace It." So Somebody Is Lying!!!!

Also, Change Your Ic Pump First. I'm Sure This Is The Problem. This Is The Most Common Problem On 99% Of These Cars. A Supercharger Problem Is A Lot Less Likely.
