'02, W-22, ABS Sensor bolts

Max Hubrich · 11-01-2007, 02:13 PM

I have an ABS Anti-lock light that came on. I'm cleaning the wheel sensors by removing them from the backing plates, and cleaning them (by wiping the debris off with a clean rag), and then reinstalling. The front wheels went well with a number E-12 torx set female socket being used. The rear wheels have some other multi- headed bolts. The #12 torx socket is too small and the #14 is too big-- one would assume I need a #13-- My little bit of research on the WEB makes me think there is no #13--- any ideas of what to use ?? Thanks,

Update--
As near as I can determine, a 12 PT 7 or 8 MM (metric, of course) socket is required. If I can ever find one, I will remove those sensor bolts and throw them away as far as I can.

I cleaned the front sensors, reset the computer by disconnecting the negative chassis battery cable, and test drove the rig. I am happy to report all is well now. The front sensors had dirt and crud on them. At least the light is out and I feel more at ease. I'll do the rear ones when I can find the correct 12PT metric socket.

I am also happy to report my first impression on the Ultra Power upgrade I just had installed. I can now cruise around on the back roads, 35-40 MPH, at 1800 RPM. Before it was always around 2800 RPM. It is also now more responsive. Time will tell on any fuel improvement. It runs great!!
