Retrofitting TPMS?
Does anyone know what I would need to do to get sensors talking to the car? Is there some module to add to the car?
It sounds like a lot of folks here think TPMS is more trouble than it is worth. I had it on previous Corvettes and liked it. Are Mercedes more issue prone?
I had it retrofitted in my cls but not an easy p&p: you'll need its control module, an antenna fitted into each wheel arc, its special cable ran for connecting all said things together .. and the system reprogrammed through DAS for recognizing the new device.
not cheap either ..

Activate in cgs
Activate in can
I don't know how can activate in ki(instrument cluster€
Install all components (harness, antenna, control unit)
Sensor wheels are not installed yet. I ll do it after control unit is recognized.
Actually I don't know what to do.
Thanks.

Controller 2118207085 (433.9MHz)
Harness 2115406207 - this one actually came with high and low pressure lines which are not needed. Can use the cheaper version .. can't recall cheaper version part number - maybe try 2114406605 ... it is way cheaper.
Antennae - I need to search for the part numbers .. it's been a while. Four antennae are needed (one for each wheel well). They are all the same but make sure that you get the right antenna for the right controller. 433.9MHz for example. The Antenna frequency needs to match the frequency of the controller.
Brackets for wheel well:
2115461743
2115461843

This is exactly what I have been looking for. Thank you once again kind sir

The other thing is that the coding was not so straightforward. I had to update my CGW software revision for some reason before the menu for the TPMS would show up ... it is strange because TPMS was available before 2005 for sure.
Lastly, I cannot remember all the steps to get this to work I flipped just about every setting in the Kombi cluster to get it to work and even then it did not want to show up right away. I think the TPMS is just finicky.

What about the part numbers for the antennas harnesses?
And the big question is ?? Does the TPMS you installed give you tire pressures as soon as you turn the key to Position 1? You installed the Beru system correct?
I want TPMS due to the fact that during a brief time of driving (4 months) between my first build where I had the IM, Heads rebuilt, front suspension, billet pulleys, F1 Fabrications Adjustable Front Upper Control Arms, and before my current latest build that started 5000 mi later at the dawn of the CCP Virus after my Rear Main Seal went and I proceeded to rebuild the whole rear end with 3.06 Gears, I was driving across Florida to Tampa and found myself passing a couple Semi's in 4th gear at around 5000rpm! A couple miles down the road I pulled over to check Oil (due to my leaking Rear Main causing white smoke to emanate from the X-pipe of my exhaust!) and I happened to look down and notice my Driver Rear Tire was completely flat!! Only the beefy Michelin Sidewalls were what kept my rims from getting eaten alive that day! Turns out I had a roofing nail hit perfectly in between treads, so I repressurized the tire and got it fixed locally in about an hour! I was amazed that the rest of the suspension/car was so evenly weighted that I wouldn't have even noticed it had it not been for my pulling over and seeing it!!! I was blown away that I made that pass without even feeling it!! Fortunately it was a dead straight road otherwise I might have realized it too late!!
After some further research in EPC, it appears that in the Model W211277 Wagon (E63) the Siemens system allows for either a 315 or 433 Frequency Antennae in the rear but only allows for 2 X 125 Frequency Antennae in the front. So, being that there are no 125 Frequency TPMS Sensors at all, does this mean that the Front 125 Frequency can recognize both 315 and 433 Frequency TPMS Sensors? In addition, it offers a non- descript Control Unit (that must pick-up both 315 & 433 TPMS in the Front & Rear) lodged in the rear. I’ve heard people chime in stating to be sure to pair the Antennae with the TPMS Sensor, but this fact throws that reasoning into question! Could it be that the 125 Frequency Front Antennae can recognize either the 315 or 433 but output at 125 Frequency to allow the Control Unit to distinguish between front and rear? Otherwise, why does not EPC list anything but 125 Frequency for Siemens Front Antennae but only list 315 and 433 Frequency TPMS Sensors for the rear? The “Tire Pressure Control” Harness that is offered are either the Code “470”, which references Fan Clutch, ABS, and TPM “Low Line 470” in its description, or the Code “475” TPC (control) & TPM (monitor), or “475 Tire Pressure Monitor (TPM) High Line/Mid Line + 489 (Airmatic Dual Control Semi Active) + 809 ( After May -2005). The latter part No. is (A211-440-10-05 or 12-05).
The W212077 (E63), on the other hand, has only the 433.92 Frequency TPMS Sensors, no Antennae in any wheel wells ( Bonus! ), One Control Unit in the Rear (A000-900-37-04) along with a short Harness #50 in Diagram (which itself may be some sort of Antenna because of its odd shape?) Part No- ( A212-540-78-13) which appears to connect to item #590 TPC Harness (A212-540-69-35) that is wired from the rear passenger side wheel well to B Pillar across Drivers Side presumably to “connect” under driver seat to the Main Wiring Harness (Hmmm?). Could this be universally “connected to” earlier (ie-2007 E63) Main Harnesses? If so, where might this harness connect to in my 2007E63? Under the NAV Unit/Driver Seat/Other? Is there a specific socket for it to connect to or is the fact that the harness comes from the Control Unit thereby mean it can be connected to the CANBUS, which can be done in multiple places, as that may make installation even easier if this harness can be run from the Rear Wheel Well to possibly the Spot Under the Rear NAV Unit?!? But that would make it too easy!
