For like the past 8 months I would randomly get the ABS/ DSC . brake trifecta that people comment about. The car would sometimes cut power to the engine. The problem went away when I installed my winter set (stock 339 wheels) and stored my apex Arc-8s, square set up. 17", matching michelin tires.

About a month ago, I started getting TPMS inactive on the Dash.

The 339 wheels/ sensors are originals from a 2012 cabriolet. I figured the TPMS were dying and didn't make anything of it. There were a bunch of random nonsense codes.

I decided to Install my Apex Arc-8s a little early to rule out that I had a bad sensor on my winter wheels. This wheel set is 1 season old and has new sensors/ stems.

I drove around for a week and still had the TPMS inactive. A couple weeks ago I dug in the the rear wheel liner area and removed the TPMS antenna. I cracked open the antenna and there was some corrosion internally.


I drove around for a week with the Antenna disconnected. TPMS inactive as expected. I ordered a new antenna for $66 from by bmw parts guy. I think I matched the part number correctly, but there are like a million versions.

I also paid one of the good guys here $35 to re-install bmw software on my laptop. I had an old version from 2017 but figured it would make sense to just start "fresh".

I tried using INPA to see if I could reset the light but was not successful. I can go E90 - Chasis- Tire Pressure monitoring system and then get an error message. Nothing found in DSC module or whatever the correct term. I did notice that when I plugged the antenna into the connector the car "woke up".

I e-mailed the sponsor that installed the software asking if he knew whether INPA could clear my light or help diagnose the problem. No response after a few days.


I have a quote to code out TPMS light for $40 from the same sponsor. I can also order TPMS module for the car for $266 from my BMW parts guy. This second option seems a little extreme/ expensive. I don't need the TPMS light to tell me a tire is flat, but I like keeping the car in good shape.


Question for the Coding experts-- What software would let me reset the TPMS antenna or actually trouble shoot the problem?

I have thread about this search the threads that I started in my profile. Use NCSExpert to reset the rdc module.
