Hi, my 2019 Mini F56 with 800 miles on it greeted me with a flat battery after 2 weeks of travel. The car had to be jump started. After that, and driving for 120 miles on the freeway everything works fine, except the remote buttons on both keyfobs, and the tpms. I cleared error codes of TPMS with bimmercod, and reset tpms in idrive, but the initialization fails at 0% with “TPMS malfunction”. Also theremote button on both keyfobs would not lock/ unlock the car. I have to use the little black button on the comfort access exterior doorhandles for that. The car starts normally? Anyone had the same problem after having a new 12 V battery installed in their car?

 

I would bring it back to the dealer. It's a new car.

 

Old topic but 'll add some insight info the problem and solution.
In case anyone encounters same symptoms - TPMS not working and stuck at 0% if trying to reset + key fob buttons not working check for any trouble codes, should see:

0x480A46: Tyre Pressure Monitor: gateway or aerial fault
0xD35694: Message (RDC data package 1, 127.0.1) missing, receiver DSC, transmitter BDC-central gateway module

Repair consist of updating software on BDC (body) module to at least 2019 I think 3rd month

 

Hi,
I have exactly the same problem.
How to update the software on BDC module.
My Mini F56 S 2017

 

Easiest is to go to dealer and have them do it through ISTA+P. It can be free if you're lucky with an honest dealership admitting the problem is of their own. If not, it'll cost you a couple of hundo's.

If you don't want to go to dealer, you'll need to acquire an iCOM kit, a 13+volt DC power supply, and run ISTA+P on your own to update the software. This may be too expensive to do and difficulty level can be high if you're not already familiar with the software and all.

Other older legacy software may work through an Esys cable, but I haven't any experience with those.

 

If its not software, then just to mention, the key fob and the TPMS both use the same receiver module. On the F5x's, I believer it is located on the rear passenger side.
