Known issues on the 2019 A6. Seven recalls are on federal record for this model year. Moisture entering the starter generator on the 2.0TFSI mild-hybrid system can cause a short circuit and increase the risk of fire. A passenger air bag with an incorrectly manufactured score line may fail to deploy properly and eject plastic debris into the cabin during a crash. A sticking fuel level sender can display an inaccurate fuel reading and lead to an unexpected engine stall. Liquid spilled in the rear seat can penetrate and shut down the gateway control module, suddenly cutting engine power. An incorrectly labeled brake fluid cap can result in the wrong brake fluid being used, reducing braking ability. A software error can prevent the rearview camera image from displaying, in violation of federal rear-visibility standards. A related software error can leave the lane departure warning system deactivated without the driver's knowledge. Owners have filed 114 complaints for the year, and no technical service bulletins are logged. The factory diagnostic and repair procedures behind each of those systems are here.
From tracing a starter generator short to a brake fluid service or a gateway module reset, it keeps you on the OEM procedure and the correct specification for your specific 2019 A6 Quattro.
