Morning, My W202 C200 with the M111 has a small oil leak from the wiring plug outlet of the cam solenoid magnet. I am a DIY-er at heart (with the backup of a mechanic for a sibling). I have seen a couple of threads with pictures where people have just re-sealed the cam magnet unit (have a drill and could buy some RTV sealent). Such as: Cam shaft adjuster magnet - Page 3 - Mercedes-Benz Forum I wonder whether such a fix is a good permanent solution, or whether I should bite the bullet and shell out for parts? The question is therefore; do I: (1) DIY repair the magnet unit as some have; or (2) Buy a replacement. If, (2) are good quality UK sources for MB genuine parts; or good qulaity aftermarket parts? How would I go about ordering the correct part, would my VIN or Engine Number help?
