My Bro has a 98 e320, the ABS and another light stayed on, we're told the sensor could be not working,
tonite i had pulled 1 wheel, i have located the sensor, wanted to un-plug her to check for continuity, but the plug kind of hard to figure out how to remove it.
We can see it on both sides, inside the wheel well and outside, but it seem to need some special tool or way to unplug it.
now i want to ask the best & brightest as how to unplug it and be able to test it.
