Hello all, My 05 R53 threw the trifecta lights. I have replaced all 4 sensors, just did driver rear and passenger front. Now my brake light is illuminated and I still have the trifecta. Before you ask schwaben shows no fault codes, every test passes. So is there something I need to do to reset the systems? My Speedo in my chrono pack doesn’t work now either, but I can see mph on my scanguage. Have checked fuses and don’t see any of them blown either. Please help.

 

Okay so i dived in deeper with scanning the R53. Live data shows that i dont have anything coming from the rear sensors, which are new Bosch sensors. I ordered a set of OEM Mini rear sensors to see if that is the issue. If i dont see any data from these it almost has to be the wheel bearings right?

 

So since garbage hasn’t been collected yet, I pulled my old rear abs sensors out and cleaned them. Stuck those in and boom all is good. Still have OEM rear sensors on way just in case.
