Anyone know the position of the RDC antenna for the tpms? Not the 4 triggers in the wheel wells but the antenna for the tpms system.

Thanks

What do you want to know? Location?

Inside the right rear trunk. Pull the liner out and you will see it.

[stevenc]

thats the rdc control unit not the antenna.

This is what I found do far

Antennas are behind the front fenders on the front part of it.

Nope thats the triggers. I did eventually find it. Its behind the drivers side front wheel well, undeneath the underside body panel. You have to drop the underside body panel which connects to the side skirts to access it.

Adding this for others who stumble here

I have a 2013 e82 135is with CCC (not CIC) and for this year the TPM system consists of the 5 components which are the tire monitors and the RDC/Antenna combo module.

The location for me of the combo box was attached to the forward of the wheel well (gas tank?) underneath the rear of the car. It is literally reachable by hand and about center. For others it seems to be under the driver side seat between front/rear wheel and you have to drop the under guard panels to access it.

I was able to successfully code out TPM system and enable FTM system with ProTool even though I am CCC and not CIC. I didn't feel like replacing the stupid RDC at a cost of $300 new or risk it with a used one.

Here is what I did....

Make backups before performing, not responsible if you brick your ride, do at your own risk.

1) Disable/disconnect physical TPMS RDC module. You must do this first.

2) Code OUT $2VB and ADD IN $265 in the Vehicle Order. In ProTool I did this by editing the string directly in the Vehicle Order editing option.

3) Change the following codes in MASK/CCC, KOMBI, and DSC:

KOMBI: RDC_ALIVE
Disable
KOMBI: MMI_ENA_RPA_RDC
Enable
KOMBI: RDC_VERBAUT
Disable
KOMBI: DSC_MIT_RPA_CC
Enable
KOMBI: RDC_DISP_SWITCH
Disable

Mask/CCC: RPA_CIC or RPA_CCC (If this exists, I can't recall)
Enable
Mask/CCC: RDC_CCC or RDC_SAFETY (I forget the name, but anything related to RDC in this ecu)
Disable

DSC: AUSSTATTUNG_RPA (it may be another name, but anything related to RPA here you enable)
Enable

Basically for this chassis with CCC you are disabling anything RDC related and enabling anything RPA related on those 3 modules.

Make backups before performing, not responsible if you brick your ride, do at your own risk.

Note that I directly edited these options for each ECU rather than allowing ProTool to overwrite the ecu's once I changed the vehicle order. You may have success there too as the idea is that when you change the VO, it will adjust the respective module options by coding them to default based on the VO edit. I chose not to do this as I had other coding options I did not want to have to go back and redo.

This is where mine was for FYI for anyone else going digging.
2011 128i (july 2010 build date).
EDIT - I ALSO had the white module in the right rear trunk. You pretty much have to remove the right side trunk liner to access it and it is in a foam block with a different Bosch unit. Don't mess w that one! This one says RDC right on it
