FTM, I couldn't remember the name.
I am lowered so because the ride height is off. It constantly thinks I have a flat regardless of what the wheel speed sensors say.

It's the same for 2 or 4 axle models. Just choose the correct one on INPA

That IS odd - the FTM has no connection to ride height, nor should ride height affect the FTM.

The FTM only reads ABS speed sensors...

Not according to the manual. I'm pretty sure I read that is uses the speed sensors AND height monitors to determine tire deflation status.

This is the wrong thread for this but FWIW, the ride height sensors don't change when a tyre goes flat. The axle AND the car both drop on that corner, so the ride height sensor doesn't (and can't) detect this.

What he said. The leveling suspension keeps the axle the same distance from the body. Tire goes flat it's not going to push the axle lower to compensate.

Well poop. Why won't the light go away. I can't reset it. Nothing happens.
In another thread I read it does his when cars are lowered with coilovers and such.

Replaced Bank 2 precat O2 sensor on 4.8iS. On that engine all 4 sensors are under the car and reinforcement plate must be removed to access precat sensors.

Check engine oil level message appeared on the display of the M54 powered 6MTE53. At 128,096 miles and 2,529 miles since the last oil service 1 quart of 0W-40 M1 was added.

Running gear service planning has commenced. For the transmission service I plan on Red Line. Should I use MTL or MT-90? I know this has been discussed before though I have seen different possibilities depending on when the thread was created. Also what should be used in the transfer case and front and rear diffs?

My car is lowered. No issues with tire pressure errors. Id check the actual TPM's on the wheels.
