In the last couple of weeks the tyre pressure monitor would trigger without actually having a flat, and then the dreaded "4X4 and ASC Inactive" on the LCD display, plus the ABS, ASC and brake lights were on. First thing that I suspected was the servo motor, but luckily this was not the case. I plugged the diags in and got several wheel speed sensor errors. And for good reason. They are filthy.

These are the two at the back. The two in the front wasn't in much better condition. I cleaned the front two last week and the "4X4 and ASC Inactive" disappeared, but the tyre pressure monitor still triggers, so I cleaned the ones in the back as well.

Now I just need to take it for a drive on the highway. Funny that it only triggers at highway speeds. But I am pretty sure this problem will be sorted.
