Hey everyone,
A few weeks ago my indy changed the front wheel bearings in my 2003 E320 sedan. We also changed one of the brake pad sensors at that time, as it broke when pulling the caliper off the rotor. (We did not have the SBC unit "disabled" as we did not know it needed done until further research.)
We had the codes ABS and ESP come up, and tried most of the hints, tips and tricks on forums to no avail. We also changed the other brake pad sensor, thinking maybe it had gone bad in the process. (This time disabling and re-activating the SBC unit with the Mercedes instructions for doing so with no Star system.)
We finally broke down and took the car to our local (45 miles away) Dealer for the $100 diagnosis, which came up that our left front wheel speed (ABS) sensor was bad, and that it would be $350 to fix.
I came home, ordered the part, and changed it myself (not a hard fix.) I made sure to disconnect the SBC unit before changing the part.
I still have the same codes on the dash, can get it reset to no malfunction until I start the car, then they come right back up.
Here's my question, is there something that should be cleaned, or could have gotten dirty in the process of changing the bearings that could be causing the diagnostics to come up with a bad front left wheel speed sensor even if the sensor is good?
This issue is making me crazy, and is not good for northern Indiana winters with no ABS/ESP.
Thank you everyone who may shed some light......
