The engine check light went on ( yellow ), cylinder #2 compression leak.

What is your question?

Boxter w/30K miles very well care taken, no racing. The engine check light went on n took to the Porsche dealer, they try ti find the problem, diagnose tool showed #2 cylinder problem, checked spark plugs, injector s, etc, measured compression n found a little compression loss. Dealer wants to disassemble the engine to check further. Cost estimate over $10K !! I suspect the engine has factory defect. Any similar defect reported ? How to solve ?
