Check engine light when temps get cold
+1 on bolts for guiding gaskets on correctly. Works every time.




The dealership didn't give me the error codes - the estimate just said cam magnets, have codes for 3 of the 4 magnets. That's why I replaced them. I didn't have any codes for the cam sensors, so I didn't replace them - I just replaced the O-rings on them.
I hear you about 'ol Murphy. If it 'aint broke don't fix it is perfectly acceptable.




Next time the CEL comes on I will see what is stored.




Is the "2720510177 MERCEDES CAMSHAFT ADJUSTER MAGNET" that part people are calling the "Sensor" or the "Magnet"? (About $30)
Parts breakdown calls it; ENGINE - CAMSHAFT & TIMING - VARIABLE VALVE TIMING - MAGNETIC SENSOR
