Locating TPMS Control Module on 2009 MBZ E350
Error message reads "TPMS Module Inoperative". Tire dealer replaced sensors in all 4 tires twice and the message still shows. Tried resetting the system by driving the vehicle per the owners manual. Tire store tried to reset it via system controls. Their testing equipment shows correct frequency is being transmitted by all four sensors. Appears that the control module is defective or not grounded adequately. Can someone tell me where the module is located on this model mbz? Thanks

I have the same problem and bought a used one for 28$ off ebay. My question is after you installed it, did you have to program it as well or just plug in and reset the tpms ?
Thanks in advance

All sources say that new sensor might take 1/2 hr of driving before control unit will pick up the signal.
I swapped wheels on my 2008 model for the wheels from other car and the sensors worked with no issue, but technology changes all the time and different MY might have it set differently.
