will 2006 thru 2009 TPMS work on a 05' W220?

 

If the frequency is the same go to tirerack.com and compare or write Luke in the forum to find out.

 

I just got the TPMS system working again on my 05 S430.

It was time to replace my rear tires, so I figured I'd go agead and replace the faulty sensor on my rear right wheel.

Actually, I replaced both rear sensors.

Got them from Tire rack -- 88.00 each for the sensors, and 8.00 each for the stem kit. Best price I've seen anywhere, even Ebay. ( Also, best service too. Ordered Tuesday afteroon -- at my door Wednesday afternoon !)

Yours should also take the same parts as mine:
RDV001- 43MM Long Valve Stem
S049 - Beru 315 Mhz Sensor (RDE004)

Good Luck!
