TPMS problem...search didn't turn up anything

AW128i · 07-28-2011, 10:03 PM

The TPMS light came on yesterday morning and so I checked the tires and everything seemed normal. Drove to work and back, let car sit for a couple hours and pressures were reading a few psi higher than they were in the AM, but I added a couple psi of air just in case. No luck, TPMS light still on. Checked again today and pressures were where I left them the day prior. Recommended pressures are 32 front/35 rear (non-sport package) and that's where I normally keep them. Right now they're at 33 front/36 rear and the light is still on. I'm using the same pressure gauge I've always used and it's a manual gauge so I don't think that's a variable. If a battery goes bad in one of the sensors, would it trigger the light?

If only it were that simple. It won't let me reset it, and comes up with a message that says Tire Low when I try to.

Had this before. It was the sensor "Base" in one of the wheels. Does yours tell you what wheel specifically? That sensor is probably fucked.

You have tp reset the TPMS target pressure while NOT moving. Reset it via the BC and then drive the car for a few miles. The BC should "learn" the new target pressure for the tires.

You can not acess the BC TPMS resetting screen while moving.

Checked the pressure before I left work today and everything is normal still. Started the car and the TPMS light is gone and it stayed off for the duration of the 35 mile drive home. Weird!
