2016 Audi A3 electrical problems

Filed Oct 14, 2026 · Airbags, Electrical · CA

My 2016 Audi A3 (VIN [XXX]) underwent Safety Recall 69BY on XXX, to correct a defect in the front passenger occupant detection system (PODS), including replacement of the occupant detection sensor. Less than two years later, the same safety-system malfunction returned. The vehicle intermittently displays "Safety system: system fault," "Audi pre sense: system fault," and "Passenger airbag off." These warnings appear unpredictably and sometimes clear temporarily before returning. This malfunction creates a serious safety risk because the vehicle may fail to recognize a front-seat passenger and disable the passenger airbag during a collision. We cannot safely use the front passenger seat. 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 the federal safety agency investigate whether the remedy installed under Safety Recall 69BY is failing prematurely, allowing the original passenger airbag safety defect to recur.

Electrical problems and fuel leak

My 2016 Audi A3 Sportsback E-tron vehicle was parked at my house. When I went to start it the engine did nothing, no power. The message “Driver System Fault” and a red triangle with a red ! in the middle was displayed on the instrument panel. I was unable to start or operate the vehicle. I called AAA and they towed the vehicle to a Recharge Hybrid pump location near my house. I tired to charge the battery and it would just turn off. Then I called AAA again and they towed my car back to my house and checked the small 12 volt battery to see if that was the problem, they determined that the 12 volt battery still had 75% life in it. They were unable to get my vehicle started. The same message is still on the dashboard “Driver System Fault." The failure mileage is approximately 81,567. I want to know before I call the Dealer and get it towed again if this issue is the Hybrid High-Voltage Battery or the housing bonded seam could have lead to corrosion the service recall from a while ago.

Epc warning light is coming and fuel tank not responding

Filed Aug 3, 2022 · Airbags, Electrical · CA

I purchased my 2016 Audi A3 in April of 2020 from Audi San Diego. Less than a year later, I was getting airbag warning lights on my dash, as well as constant warning sounds when driving. I brought my vehicle into Audi San Diego, and they "fixed" the issue free of charge. A few months later, I started getting the same warning lights/sounds - this time, the passenger airbag was turning on and off even while somebody was sitting in the passenger seat. I received a recall letter in the mail shortly thereafter. When I called in the summer of 2021 to schedule a service appointment, I was told there was not yet a remedy to this recall and that in the next few months I should receive a phone call to schedule service. Over a year later, I called Audi San Diego to get an update (since I did receive a phone call as promised), and I am still told that there is no solution. For over a year now, I have been unable to have passengers in my front seat, due to the fear of the airbags not working in the event of a crash.

While driving the message “Vehicle Electronic System Malfunction Shift Car to Park Before Exiting Vehicle.” The car can fail to shift into gear, or change gears while the vehicle is in motion. The mechanic that I usually take my car to said that’s he’s seen the same message in some of his other customers cars. Sometimes it pops up when the car is started, other times is comes up when the car is in motion. I’ve parked the car and turned it off, and the message came back on after restarting the car.
