1 of my valve stems is pooched & the TPMS didn't work when I purchased the car. You guys using the TPMS, if so, where should I purchase from?

Would prefer to invest the TPMS money into something performance or rim related.

Mine are gone. It's annoying see the message in the display but my son (MB tech) is going to code it out. He said our cars only show low air. Not a specific tire low on air.
It would be nice to have it to prevent damaging a wheel.

I've always driven old cars and never had tpms. I always keep a check on the tires and pressure.

The E55 TPMS does show individual tire pressures.

tlambert

Good to know. I would install it back since it shows individual tires.
Thanks for the info.

Does the 2007 E63 have TPMS and does it show individual tire pressures? Anyone know off hand?

These are available at many online venders: Amazon, Autozone, Etc; I found four for $150, others around $90/wheel

Yes it does:



TPMS has been useful for me. There was a slow air leak coming from one of the tires that TPMS threw an alert on after around 7 hours. I would have never known from visual inspection. Since I have warranty coverage on the tires, I drove to America Tire and they found a nail...

use star to turn off function so you wont get warnings. I turned it off the first week I got my e

One day I'll retrofit it in both my E's. I think this is one of the most useful features in our cars.

Hotsauce55

i did that exactly Now that I need new tires, its on my mind. I think I'll pass on making it work for now.

Besides the sensor in each wheel and coding the car, what else is needed? A receiver for the sensors and is the car prewired?

Mackhack

Sensor in tires, 5 antennas, control module, wiring harness from all 4 wheel houses to trunk and to center antenna plus version coding.

Oh thanks! A little more time and effort than I feel like dealing with at the moment.

Mackhack

That's why I'm hesitating too. Wheels need to come off, plastic lining inside the wheel houses need to come out, seats and carpet might need to come out to route the wiring harness properly. So yes nothing if you don't have time and a garage where you can just leave everything.

Edit: There are so many more parts involved that need to be replaced. A VIN of a car that has TPMS put in by factory would be helpful to compare parts. There is nothing worse than having half the car pulled apart and realizing seals and what not are missing.
