Audi A6 Recalls

The Audi A6 has 66 recalls spanning 1994 through 2025, with the most serious recent issue affecting 2019–2022 model years, where liquid spilled in the rear seat can shut down the gateway control module and cause a sudden loss of engine power while driving.

On the current generation, a 2022 engine control unit semiconductor can short-circuit and stall the engine. The 2025 model year has a seat belt retractor that may fail to lock when securing a child seat. On 2021 models, a door crash sensor connector can detach, delaying the side airbag, curtain airbag, and seatbelt pretensioners in a side impact. Also on 2021 models, the instrument panel display can go dark due to a software error, hiding the speedometer and warning lights, and the rearview camera can fail to display. A fuel level sender on 2019–2022 vehicles can stick and show an inaccurate reading, potentially causing an unexpected engine stall. The passenger airbag on 2019–2021 vehicles may not deploy correctly through the instrument panel and can send plastic fragments into the cabin. A rearview camera software error affects 2019–2025 vehicles, preventing the image from appearing when reversing. On 2020–2021 models, a rear axle lock nut can break and misalign the rear axle, causing loss of control. The 2019–2020 mild-hybrid models with 2.0T engines have a starter generator that can allow moisture in, causing an electrical short and fire risk.

Going back to the mid-generation cars, fuel rails on 2016–2018 vehicles can leak near an ignition source. The auxiliary heater electrical connector on 2015–2016 models can overheat and start a fire. The passenger seat occupant detection mat on 2012–2018 vehicles can wear and cause the front passenger airbag to misfire or fail in a crash. Fuel hoses and fuel lines on 2012–2014 models can degrade or weaken at a compression point and leak fuel. An electric coolant pump on 2012–2015 vehicles can overheat and raise the risk of fire. A curtain airbag stitching defect on some early-production 2012 models means the bag may not deploy in a crash. The passenger airbag inflator on 2005–2011 vehicles is a Takata unit that can rupture and send metal fragments into the cabin, a defect that prior repair attempts did not fully resolve across all affected vehicles. The 2017 model year has a recall covering airbags and seatbelt pretensioners that may not function properly in a crash. A passenger seat sensor malfunction on 2012–2018 vehicles can cause the front passenger airbag to deploy incorrectly.

On earlier production, the 2003 model has a driver airbag igniter that may not have been properly assembled, preventing deployment in a crash. The 2001 model year has fuel tank rollover valves that can crack and leak fuel, and windshield wipers that can tangle and stop working in heavy weather. The 1998–2000 models have driver airbag inflators that may not protect occupants properly in a crash. The 1998 model year carries several issues: a throttle that can freeze open in extreme cold and prevent the engine from returning to idle, headlight switch wiring that can short and start a dashboard fire, steering tie rod seals that allow moisture in and cause the steering to feel loose over
