Problem car 100HP

Hello, I got my 100HP new in Dec. 2007. The first 24 months the thing was also fine. Good driving characteristics, great acceleration and a super chassis. Hardly the warranty time has expired, already the defects begin. after 26 months (approx. 25000km) wheel bearing at the rear right defective. After now 30 months (29000km) my 100HP simply stopped. Then with three cylinders still to the workshop of my trust (now no longer). There it is now, for six days, first diagnosis Z Misdiagnosis. When checking the compression was detected, no compression on the second cylinder. Unfortunately no further feedback so far. Does anyone have the same problems so far? Greetings Magiccarlos
