Known issues on the 2020 A6 allroad. Nine recalls are on federal record for this model year. Rear axle misalignment may cause premature or uneven tire wear, increasing the risk of a crash. An incorrectly manufactured air bag score line may not deploy properly and could also eject plastic debris into the passenger compartment, increasing the risk of injury during a crash. A broken lock nut on the rear trailing arm may misalign the rear axle, causing a loss of control and increasing the risk of a crash. A short circuit in the starter generator, caused by moisture intrusion, increases the risk of a fire. The passenger air bag may not properly deploy and inflate, and small plastic parts may enter the cabin, increasing the risk of injury. An inaccurate fuel reading from a sticking fuel level sender may cause an engine stall due to lack of fuel, increasing the risk of a crash. A gateway control module shutdown, caused by liquid spilled in the rear seat, will suddenly reduce engine power, increasing the risk of a crash. Incorrect brake fluid, from a mislabeled cap, can reduce braking ability and increase the risk of a crash. A software error may prevent the rearview camera image from displaying as intended, reducing the driver's view behind the vehicle and increasing the risk of a crash. Owners have filed 24 complaints for this model. The factory diagnostic and repair procedures behind each of those systems are here.

From tracing a gateway control module fault to a rear axle alignment check or a brake fluid service, it keeps you on the OEM procedure and the correct specification for your specific 2020 A6 allroad.
