Thank you for your assistance. it is a perplexing problem. I am using an Innova OBD II scanner. It does have some BMW features but does not have the feature to register the RDC/TPMS module to the chassis. The Autel tool has an OBD II connector and does have that ability. The Autel tool actually makes me go through and choose the make, model, year, and series of my BMW when diagnosing the TPMS and performing the relearn procedure. I’m going to try going the battery reset route first. If that doesn’t work I may need to buy an OBD II tool specialized for BMW That includes the diagnosis and relearn/registration procedure. I will keep anyone reading this post updated. Thanks. Keith

I’m having an issue with my RDC on my 2014 X3 TPMS system. I purchased a new module and installed it. I used a TPMS coding tool (Autel TS508) and it registered everything fine and the system worked. I actually drove the car several hundred miles without a problem. The issue I’m having is that when I shut the car off and then start it back up, I get the TPMS malfunction message on the monitor. I can go through the same set up process with the Autel tool and get it to work again. Each time I shut the car off, however, I get the same error message when I start it back up. It’s almost like the computer memory isn’t holding the information. I recently purchased a new battery, registered that using a different coding device on an OBD II scanner. I had to reprogram the sunroof. That all worked fine. I did replace the RDC module after that. I have not disconnected the battery since. I’m wondering if I need to do that and then go through the whole process again with the OBD and Autel tools. Any advice or help would be appreciated. Let me know if anyone else has experienced this issue. Thank you in advance.
