W204 Just fixed my abs lights on dash change wheel sensor didn't work so I checked plug an found that I'd bent one of the pins. I straightened it and plugged it back in trying to feel it go in. I thought how to test it so I had a bought a new hub ring so I put my topdon tester on and stroked it with the magnetic hub ring and got a reading so I'm going to do this as a test if I get any more problems with merc abs system. Hope this helps any members.
