TPMS question

. Probably need to replace the TPMS module. There seem to be a lot of TPMS part #s and MHZ operating frequencys being sold for Mercedes. What is the part # that I need for my 2012 E550 it gives the PSI on the dash (if that matters).




Even more important now with TPMS where you can actually read the TP's in each tire.
The metal caps will fuse or rust to the metal valve stems.

Dorman 974-043 Tire Pressure Monitoring System Sensor https://www.amazon.com/dp/B0049EDY3S/ref=cm_sw_r_awd_Yv45vbZ84XZSA
Had a local Les Schwab put them on for me ($73.73 for labor) today.
They told me I have to drive the car at at least 10mph for ~15min for system to learn new sensors. Drove it for like 30 min and the sensors were still showing up as "missing" on the dash display. Figured I took a gamble and lost. Drove home, was there for about 30 min. Decided to go give the "learning process" one more try. Drove around the area for about 15 min, tpms numbers came up and now shows all 4 sensors in working order.
Part supposed to fit the 2010-2012 models. A reviewer on Amazon with a 2011 model also seemed to have success with these.
Figured I'd share, in case you feel like trying them out. Good luck haha
