Just wondering what you guys have used and where you bought them?

I bought a set of Seimens tpms from them for $117 shipped. They were the same as the ones that were on my main set. I had them installed yesterday for $10 each. The tire placed used a tpms activation tool on them.

oewheels.net (oewheels.llc) gives you a set of four for $112. Absolutely nothing needed to get them up and running. 2007 GL450.I bought five and had to add $10 for shipping.

Tires have to be dismounted.
However, they don't have to be re-balanced. So it's like $10 per each.
TPMS live about 10 years. So if you're within tire lifetime of 10 years, change them when you change tires.
If your tires are near end of life, I'd just live with the TPMS error.

Or you could just not install the sensors and have someone with a MB Star turn the system off, this extinguishing the warning light in the dash.
You'd be on the hook for checking your tire pressures regularly.
Flame away.

Flame? Why? We'd love to go back to the days of NOT obsessing about TP's!

Correct, you'd need some DAS compatible tool to program out the TPMS function in the Central Gateway Module. I've done it to both my 07's - mostly because I air down on some rougher surfaces and don't want to stare at a yellow light when I do, and didn't want to pay the extra $$ for the sensors.
FYI I believe TPMS like systems were required by law for 08 model year and up so tire shops are legally obligated to sell you TPMS or decline you service.

I don't know if they're always on or if the car sends a wakeup signal on the working frequency as part of startup.
I do know that it takes 30 minutes from when a sensor has failed to when the light and message will trip, so there is some periodicity to checking if the sensors are still there and operating.
Now, that's not to say that it takes 30 minutes from a loss of pressure incident to the report. That's instantaneous.

The wikipedia article says the simpler TPMS only transmit when rotating. I guess their signal is a simple "pressure okay", at least in the 07 GL. Since the system doesn't know which tire is low, I guess it also just looks for four different signals, expecting them on fixed intervals (30 minutes? When I air down, I get the error messages much sooner than that.)
It's possible the sensors send a "low battery" signal on the 30-minute interval. The "low pressure" signal may be a discrete signal, or simply no signal at all.
There is a more sophisticated variety that have two-way communication. Since the GL system is crude (doesn't know which tire), I assume it's receive only.
Edit: A lot of crummy articles. Here is a better one: https://www.brakeandfrontend.com/dec...reless-signal/
Also note the GL has both an indirect (comparative wheel speeds) and direct (in-wheel module) TPMS. The former is the little orange light looking like a tire cross section, while the latter turns the center display red.

Okay, I'm officially retarted for not thinking of that.

In a way, it's a good thing. I rotate my tires all the time - I have five wheels and rotate them through - and I'd go nuts if I had to reassign transmitter IDs each time.
