B1225 fault code: what 11 owners reported

…On XXX, at 74,151 miles, Audi Marin diagnosed the malfunction and documented fault codes B102202, B102229, and B12251B. The dealership confirmed that diagnostic testing continued to indicate a faulty passenger occupant sensor (G128) and recommended replacement. Audi Marin's service manager informed us that Audi has redesigned the replacement component, but the updated part is on an extended backorder from [XXX]. The dealership cannot currently complete the repair. Audi of America acknowledged the prior recall repair but referred repair coverage decisions to the dealership, citing the expired warranty. The vehicle remains unrepaired and is available for inspection. I request that NHTSA…

I got a Safety System Malfunction! Fault. I took it to aan Audi dealer and they said it was an issue with a harness under the passenger seat. Tech notes here references a service bulletin. Air Bag Occupant Sensor - Replace | faults present b1225f1 - tsb 2051242/7 -- per tsb apply wiring ties to secure and prevent faults from returning -- not covered under extended warranty policy. Not sure why this isn’t covered under extended warranty or a recall. It basically disables the passenger airbag. I have seen other Audi vehicles with recalls for similar issues with harness under the passenger seat. I think they have a design issue but are wanting to charge me (and probably others) $220 to diagnose…

Component Affected: AIRBAGS: FORE AND AFT INTERIOR OVERHEAD/OCCUPANT CLASSIFICATION SYSTEM Description of Safety Defect: I own a 2013 Volkswagen Beetle 2.5L (Build Date: April 2013). The vehicle is experiencing a permanent Passenger Occupant Detection System (PODS) failure, indicated by a persistent airbag warning light on the dashboard and an active passenger seatbelt warning chime. A diagnostic scan reveals active fault code B12251B (Passenger Seat Occupant Recognition Sensor Mat - Resistance Too High), pointing directly to a failure of the digital 3-pin LIN-Bus occupancy sensor module (OEM Part Number: 5C6959339B). This system failure suppresses the passenger-side airbag deployment…

The passenger side air bag warning light and/or passenger seat sensor mat has failed 3 times (twice since we've owned the car and once before). We purchased a used 2017 A4 Audi Sedan in October 2019. In early November 2020 the passenger side airbag warning light came on. After adjusting the front passenger seat, the light went off. Thereafter, the light would intermittently go on and off. We took the car to the dealer from whom we bought it - Royal Automotive Group in San Francisco. Their technician tested the car and confirmed a fault code #DTC B1225F1. They found "tsb #2051242/5 for issue and fault" and installed "cable tie per tsb." We continued to drive the car without incident until…

My 2018 Audi A5 Sportback previously received Audi Safety Recall 74E3 on January 27, 2023. The recall repair documentation indicates a seat POD (Passenger Occupant Detection System) update was performed. Several years later, the vehicle developed another passenger airbag fault. The vehicle displays a message indicating the front passenger airbag is OFF even when an occupant is seated in the front passenger seat. Audi diagnosed fault code B12251B, "Passive Occupant Detection System Mat Resistance Too High," and determined that the seat POD occupancy mat and wiring are defective and require replacement. Audi has refused to cover the repair because more than 12 months and 12,000 miles have…

My Porsche Service Center advised that the front passenger airbag sensor of my 2016 Porsche Macan Turbo is not functioning properly. The identified fault was: Airbag (variant 002) B12251B "Seat occupancy sensor on passenger side (BOSE) - resistance too high" I have been advised that NHTSA has issued two recalls on this problem. My Porsche Service Center has advised that the originally installed passenger side occupancy sensor was replaced pursuant to one of the recalls. Despite the same problem affecting the presently installed passenger side occupancy sensor, my Porsche Service Center has advised that it is not subject to a recall. It has proposed repairing the sensor at a cost to me of…

…THE ERROR CODE WAS B12251B (MAT RESISTANCE TOO HIGH). AUDI'S INTERNAL DOCUMENTS ACCESSED THROUGH NHTSA REPORT THAT "IF FAULT, 'B12251B: SEAT OCCUPIED RECOGNITION SENSOR MAT RESISTANCE TOO HIGH' IS STORED IN THE AIRBAG CONTROL MODULE, DO NOT DIAGNOSE OR REPLACE ANY COMPONENTS FOR THIS FAULT BEFORE PERFORMING THIS REPAIR.

HOWEVER AUDI PERFORMS THE CHEAPER BANDAID OUT OF POCKET AND EXPECTS THE…

On my dashboard, my passenger seat airbag started going off. I brought my VW Beetle in for its 100,000-mile maintenance check and asked about the airbag. My mechanic informed me that the passenger seat airbag was failing, and if I were driving with someone and crashed, their airbag would not deploy. They told me there was nothing I could've done to prevent this, it's just the piece itself has failed. Their advisory notes were: 'Airbag light on trouble code B12251B occupied recognition sensor mat. PART #5C5959337.' I researched if my car was eligible for a recall and it is not, however I saw that VW has a recall for Takata Driver Front Airbags.
