Successful RDC replacement
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. |

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 (Thanks shawnsheridan for that bit of text.) |
