TPMS RDC Module
Posted: Mon Jan 29, 2024 8:52 pm
Hi all,
I recently have had TPMS failure messages randomly flag up on the iDrive and then disappear with no intervention on my part.
When I had new rear tyres fitted a few months back, I was advised the valve stems were showing their age and I assumed the error could be connected so was planning to replace them when I have my wheels refurbed in the spring.
At the beginning of last week the TPMS error became a permanent fixture and then, fairly shortly afterwards, all sorts of other intermittent issues occurred such as central electronics failure flagging up, dashboard warning lights flashing on and off, bouncing gauge needles etc etc.
My first thought was tired battery as it was the original one and nearly 8 years old. I know dodgy batteries can cause all sorts of issues on BMWs so have replaced that, unfortunately with no change.
I've now checked error codes and the one which caught my eye was A3C3 RDC Failure, the RDC being the main module for TPMS. I've also watched several YouTube videos which show different model BMWs with similar electronics/warning light issues and the RDC module was the culprit in those cases too.
Apparently this can be 'proved' by disconnecting the module and all the other electronics issues should disappear.
My problem is, I have no idea where the RDC module is located on a 2016 E89 and I can't find anything to help on the Internet.
Can anyone help with where it might be so I can check this out?
Thanks in advance for your help
Andy
