I have a 2015 C300 that my check engine came on P0016 . I changed the crank sensor at 11 o’clock rear passenger side with a Mercedes one and cleared the code and started up ran good shut the car off and start again the code is back ? Replaced left camshaft sensor with a Bosch no change ? Didn’t know if changing the right cam sensor would make a difference or possibly check the cam magnets ? I have 110,000 miles any help would be greatly appreciated.
