But how can I reset it myself? I doubt the dealer will tell me. He's just tell me to bring it in for more costly service that should have been done the last time they forgot to re-set it.
Like how the car came with metal RFT tire stems. But every time they "service" the car, it comes back with silver plastic tire stems. I once bought all chrome caps from Auto Zone. After the next service, I got silver plastics back again. It just irritated me that some wealthy Palm Beach dude driving a 740l BMW was driving around with my chrome metal tire stem caps.
Living in South Florida, where day time temperatures can be over 80 degrees and in the winter, might go below 50 degrees at the ground, they don't tell you that the reason that all four Tire Pressure Indicators go off is because you just need to re-set the indicators. Not bring the car in for more expensive service.
Proving once again that liquids and gasses expand and contract due to rising or falling temperatures.
