Wheel speed sensors.

[Rob & Sandra]

Morning. I think this is quite a common problem/failure. Question has anyone used aftermarket sensors from other retailer rather than Mercedes original.

There is a massive price difference £150 each from Merc or circa £22 from several other suppliers, it’s a simple Hall effect sensor.

Good morning. Just had a failure of wheel speed sensor. Have now had three replaced in the last 12 months. Two were after market. No problems with them so far. Mercedes service fitted the last one roadside. Took him about 20 minutes.
