bmw g31 TPMS RDC module replacement

[Billy_Whizzzz]

Replaced my sensors 6 months ago - and now there is a RDC failure message. When I reset it gets stuck on be dreaded 49%. Presume I need to replace the TPMS RDC module? Where is it located and how easy?

I'd get a fitter with the right kit to check the sensors again first. If it's getting to 49% the module must be working to an extent.

I had a sensor go 10 months after replacing it so it does happen on occasion especially this time of year when the weather's not great.

Honestly find it baffling that not even BMW seem to know where the G31 RDC module is

Probably drivers side C pillar (depending on age of your car?)



Thread below should contain all the info you need. I bookmarked it a couple of years ago whilst diagnosing & fixing the same problem on my M135i (new RDC module)
