Hi, I have a W202 1999 C220 CDI which appears to have a fuel leak at the injectors of cylinders 1 & 2. There is an accumulation of about 1 millimeter of diesel on the cylinder head in the well for the injector on cylinder 1 and about half that around cylinder 2. Around cylinders 3 & 4 it is clean and dry. When serviced about 1 year ago injector seals part MA611 017 00 60 were replaced on the injectors for cylinders 1 & 2. The MB garage want to keep the car for 3 days before giving an estimate for the repair cost. How dangerous a fire risk is it to drive in this state please? Any advice gratefully received.
