2010 ML350 Brake Wear Lights
My ML350 has a brake wear indicator problem that will not turn off the Brake Wear Indicator on the dash, does anyone know how to clear off dash? Also I have a tire pressure warning constantly popping up, i have checked all tire pressures and they are all 33psi. Does anyone know where to direct me with either of these? Thanks in advance!

When you get the Brake Wear Sensor Light on it means that your brake pads have worn down. Didn't you think of this?
As for the tire pressure monitor, which tire is it? It could be the sensor on that wheel that could be faulty.

There is a break wear sensor on the front right and rear right caliper. Pull those wheels and look at brake pads, if low that will trigger the light.
If brakes are required, change them.
If not, the harness for the front wear sensor is known to go bad, so replace it.
I did all of the above and still had the error. Turned out to be a broken wire on the rear harness. The harness from the brake plugs into a connector in the fender well, and after that connector along the wire it was broken.
Reset the TPMS system in your instrument cluster menu after correcting all tire pressures. If it still goes off, it is a sensor. These sensors last 7 years so if you have original ones replace the entire set.
