So the RDC module on my 2011 X3 (F25) died and I bought a used RDC module from a 2016 X3.
The "TPMS Malfunction" warning still came up after I replaced the module so I figured it needed to be flashed or coded.
I looked into using ISTA-P to "Program" it or Esys to "Flash" it. However, due to the Integration Level being too old, the Program or Flashing will need to update multiple ECUs and potentially update the I Level (which I can't do since I don't have a 70A battery maintainer).
After some research I found some directions about "coding" the RDC module. This worked out for my replacement part as it already has software on it but just missing a CAFD file.
So I followed and updated the instructions below using Esys and everything worked out fine. Hope this help others who have the same problem.
Once connected : -
Expert Mode-Coding
Read FA
Activate FA
Read SVT
Select "Complete Flash" and then choose the I-Level for "Shipment"
Select the 'RDC' ECU
Detect CAFD for SWE (you will see a list of compatible CAFDs)
Choose the CAFD you want (since they are all the same, I chose the latest one)
Click Code
DONE

Bought my RDC antenna new from BavAuto. Then had my buddy at his Indy shop program it to car. Taking out and installing was super easy. Thanks for sharing.
