Airbag warning light illuminated: Seat belt tensioner fault?

I own a BMW 3 and have a problem with my airbag warning light, which is constantly on. After a fault analysis, the belt tensioner is shown as the fault. What could be the cause of this?

(Translated from German)

Summary of the thread

The airbag warning light in a BMW 3 Series is constantly on, with a fault analysis indicating an issue with the seat belt tensioner. Despite replacing the connecting cable, the problem persists. Possible causes include a faulty belt tensioner, insecure connections, or the need for fault code clearance in the airbag control module. Suggested solutions involve re-checking the installation, rescanning and clearing fault codes, and consulting a professional mechanic or BMW specialist.

Hello Gerado101, If your BMW 3 Series airbag warning light remains on due to a belt tensioner fault despite replacing the connecting cable, consider these possibilities: the belt tensioner itself could be faulty, connections might be insecure or improperly made, or the airbag control module may need a fault code clearance. Other potential issues could include broader electrical problems or a need for software updates. Re-checking the installation, rescanning and clearing any fault codes, and consulting with a professional mechanic or BMW specialist are recommended steps to resolve the issue. Please let us know how it goes.

Hello Umut, The fault message "0093C2 iDrive 'Belt tensioners and belt force limiters faulty'" that appears and disappears when a passenger exits the car could be due to a malfunctioning seat occupancy sensor, loose or corroded electrical connections, issues with the control module, or a routine system check. It's advisable to conduct a diagnostic scan to pinpoint and resolve the issue. Let me know if this helps or if you have any further questions.
