Camshaft Position Sensor
Hello Everyone,
My first post here. Thank you in advance for the help. I have a 2010 Mercedes E350 4matic and after scanning with my friend's Mercedes scanner, I am getting a code for a camshaft position sensor. There is no check engine light on, the car does not stall, the car does not have a hard time starting either. It does run a little rough though. Should I start with transmission mounts, or should I change the camshaft position sensor also? How many are there to change and where is it located? I believe that it is in front of the motor, but there seems to be 4 of them.
Thank you very much

If your camshaft position sensor senses are bad, that will cause the check engine light to come on, engine and transmission mounts will not cause the check engine light or any other warning lights, but it will cause vibration and rough drive. Change the engine and transmission mounts first.

Any time you scan the car after long period, observe if the codes are stored, or active.
Every time I purchase used vehicle, I read average 30 codes on it, what is from all the times when battery went bad 2 years ago, TPMS malfunction and such.
Than beware that programs for CEL require the code to be repeated and and have different requirements for different codes.
Meaning pending code can pop on hard acceleration without triggering CEL and if you don't do heavy acceleration for some time it mighty clear itself.
Bottom line, with no CEL, clear the codes, read them again after a day of driving and if they don't come back - don't lose your sleep over.
