Successful RDC replacement

richardodn · 04-27-2021, 06:03 PM

This is not a DIY, but I did want to post that I was able to fix my failed RDC receiver with a new BMW part. It does require coding after the installation which can be done with E-Sys and an Enet cable. I spent about $260 for the RDC receiver module for the TPMS.

Physical installation was straightforward. On my 2012 it is located under the car near the RR wheel. I set E-Sys up on an old laptop. After an hour or so of messing with stuff, I finally found the magic dance to perform the coding. This makes me a happy camper as I really didn't want to code it out.

thats awesome Richard

mind sharing with us the clicks you performed on your laptop?

may be good info, for someone in the future

I'll try to retrace my steps. I'm sure I made a bunch more clicks than was needed. The main reason for this post was to state coding is necessary and E-sys can do the coding. When I was researching how to do it, nothing was definitive.

The operation is known as CAFD injection and we are performing it on the RDC ECU. The steps are roughly this:

Using E-sys...
Connect => Read FA (VO) => Activate FA (VO) => Read SVT (VCM) => Left-Click on RDC ECU => Click on "Detect CAF for SWE" => Select the CAFD from latest I-Level shown => Select OK => Right-Click on RDC ECU (the ECU itself not the underlying CAFD) => Select CODE
