How can I know which TPMS frequency my 08' ML350 uses ?
In some website, they stated there are 2 freqs used in some MLs and GLs production, which are 315 and 433 Mhz.

My 2007 uses 433 Mhz, hope that helps...

My '08 ML550 uses 433 MHz as well. If you absolutely, positively need to know what's on your wheel, have a tire shop dismount one tire and read the frequency off of the sensor. There are also scanning tools capable of reading the frequencies and doing resets for TPMSs.
