I recently went to my nearest dealer Crown Euro-cars of Dublin, Ohio, to see about ordering a Camshaft Adjuster Magnet which was leaking oil. I was pleased to find out that this was considered a "Warranty" item for my 10 yr old 116K mi. car. They provided my with a loaner, replaced the engine wiring harness; engine control module; and other parts damaged by oil siphoning through the electrical system, all at no cost. The rub? Instead of replacing the leaking part (I ordered it on E bay for $80) Mercedes only authorizes a jumper to keep the leaking oil out of the system. All that time & money to fix the damage, & still the car leaks oil (apparently Mercedes parent company is Harley Davidson). Kudos to the dealer for great service, a Razzy to Mercedes on a cheapo fix.
