I have a 335i 2007 sport package, 19inch rims with OE sensors working fine until recently I start getting TPMS Malfunction/ Inactive. I took it to American Tire Depot and they tested all 4 sensors all reading correctly, also I took out the RDC (white module in the back) and checked also since I have electronic background I replaced the only thing which could be bad the capacitor in the control unit.
Also I replaced two sensors for the front tires OE exact part bought from Tomkinson BMW parts online. (Good online prices). I have 33PSI front and 37PSI Rear. If I run the car in the morning it works fine for the first 10mins and then inactive start decorating my dashboard plus the annoying noise. From I-drive I reset the TPMS 1 zillion times and took out the battery over night one time. I took it to BMW dealer (Southbay CA) tech reset said no errors found again I drove for another 10mins and the light comes back. Before I give up any ideas? Will the antenna do this? Should I replace the Antenna? And where is located? I have the Bentley manual but didnít find anything about the RDC Antenna!!!
HELP PLEASE text me if you have any idea 513-410-9363
Thanks in advance
My car, 2010 328ix, has TPMS problems too. After spending $150 at a dealer for diagnosis, I was told the RDC module and the connector plus cable need to be replaced at $900. Not to mention how frustrating it was to find information of this system, which is not very useful except creating some annoying warning sign at the dashboard. Here are some info to share with you. The TPMS system includes: 4 tpms sensors in the 4 tires that talk to 4 triggers (black rectangular shape) located in 4 wheel-wells. there is one "RDC control module" (white rectangular block, normally installed in the trunk above the battery) and one antenna, normally underneath the car. But, for the new model, the RDC and the antenna are combined into one component about 3" long and 1" x 0.75" in size. This module is normally installed underneath the car. Mine one is located behind the right rear wheel and underside of the trunk.The connector of this module is NOT sealed for outside use! (unbelieveble poor design! very unprofessional). So over time, water gets in and the connector is corroded.
This error can appear when a specific wheel TPMS goes out. If you scan with a BMW style tool, it will indicate a specific wheel in addition to the system. Note, the sensor may still read as good at the tire shop.
Replacing the TPMS sensor in that wheel was the solution on my vehicle. $65 including parts and labor at Discount Tire. Quote was $260 at the dealer.
