I have already replaced the original connecting cable between the belt tensioner and the wiring harness
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.
