So, I've been looking for TPMS for my new to me R63 AMG. The prices for OEM seemed crazy expensive like $100-$160 per TPMS. Even the aftermarket varied a lot and some needed programing of the units using a tool. Prices were $35-100 each. So after much research I can tell you the following:

For 2007-2009 R/ML/GL all models use 433 MHZ monitors. The information in this thread is correct:
TPMS frequency

The following mercedes part number will work correctly in all of these cars:
A0045429818

Original part numbers were:
0025408017

I got a full set for $112 +5 dollars shipping just by googling them. Got them from OEwheels LLC. The customer service from them was very good.

These did not require programming of the units, just reset of the Mercedes system on my car and bam everything works well. These are real Mercedes parts that have the Mercedes part number and say Siemens VDO, right on the units.

I hope it is OK as I'm posting in R, GL, and ML forum so others can see.

I bought a set of 4 new sensors, Mercedes branded, off Ebay for $130 last year.

Costco installed them and programmed them just fine when they replaced my tires.

Yes - 433 MHz for my 2010 ML350

I am not sure the part number - won't let me view the item description on Ebay since it is 1 year old.

But they had the Mercedes stamp on them.

Thanks for the tip! Ordered 4 TMPS wheel sensors from OW Wheels for my 2007 ML500. Working great. No programming or computer required. Installed the sensors on the wheels drove for about 20 minutes and the warning light went off. Cooled the tires overnight, set the pressures where I want them and pressed the R (reset) on the dash while on the TPMS screen and all is well.

Item: 9489257
Description: TPMS fits Mercedes Benz ML500 2007 - 433Mhz Tire Pressure Sensors SET-TPMS-Siemens- A0045429818
Price $112 plus $5 shipping for 4.

For reference the OEM was a Siemens VDO A0045425718
The OE Wheels supplied Siemens VDO A0045429818 appears to be a direct plug in replacement.
