Service tire monitor system light

@dagosa, and I thank you. At least someone around here will do what I tell them to do!

“I wonder how they pulled that one off since I thought the regulation required sensors in the wheels?”

Apparently, VW Group and BMW have also gone back to the ABS-based tpms. I guess the ABS sensor is technically in the wheel assembly.

“they often fail to agree with correct pressures”

I have found them to be extremely accurate

Let me qualify that statement

The systems which display individual pressures on the driver’s multifunction display are very accurate

If using a scan tool, the pressures displayed for the individual sensors are very accurate
