Crankshaft Positioning Sensor


The CPS sensor failure should be less frequent on a W211 actually, perhaps you should feel lucky.
My 221 had a CPS recall although I have not heard of problems, at least no symptoms in my car.This a relatively cheap issue to identify and fix. The radiator leaks are more serious issues with the 211, one facing that issue deserves to be angry.
It will last longer than the warranty period in most cases and is not a recall item (these are safety and emissions only).
