In August 2020, Volkswagen / Audi received an inquiry about a gateway control module failure in an Audi Q5 vehicle in China. An inspection of the situation found that the gateway control module had gone into fail safe mode because of liquid entering the module from a rear bench seat spill.
The gateway control module has been programmed to go into a fail-safe mode when an implausible signal is detected in the control unit. If an implausible signal is detected, the gateway switches off its function in order to avoid unwanted vehicle reactions. The vehicle remains steerable and the brake system will work, but the engine will go into emergency mode and remains in operation with reduced power.
Audi performed a safety assessment to evaluate the potential conditions and consequences that could result from a power shutdown of the gateway control module due to liquid ingress. Audi also conducted a risk assessment which indicated that the risk of a liquid spill leading to a failure of the gateway control module is very low and rare over the lifetime of the vehicle. At the time there were only isolated cases in the North American region and all of them happened after an outside influence, mostly after a beverage spill. Audi continued to monitor the problem.
In March 2021, Audi experienced an increase in customer reports related to gateway control module failures on Q5 vehicles after a liquid spill. Audi conducted additional testing and continued to investigate a potential solution to be implemented in production and in the field. Due to single field cases alleging the failure without a liquid spill, an additional investigation was initiated to rule out other root causes for liquid ingress. In August 2021 Audi identified a potential manufacturing issue in the factory in Mexico. “Due to a programming error of a glue bead robot, an underbody seam may not have been sealed sufficiently and therefore allow water ingress from underneath in very rare cases when driving through heavy rain or deep puddles.” The adjustment to the robot was implemented immediately and analysis continued regarding the impact of this additional potential cause for liquid ingress.
The Audi Safety Committee began to issue a service campaign in order to install a protective cover for the gateway control module and to seal the underbody in the area of the insufficient glue bead, but after a meeting with Transport Canada and the Defective Product Administrative Center in China, the Audi Product Safety Committee re-evaluated their decision and decided to conduct a voluntary recall to fix affected vehicles.
|The Vehicles Affected Include:
|2018-2022 Audi Q5 Sportback
|2018-2022 Audi SQ5 Sportback
Volkswagen will be contacting owners of certain 2020 Audi Q8 SUVs, regarding a potential problem affecting the transmission in their vehicle.
Due to a manufacturing error, the flanges of certain gearbox oil pipes were made from an uncertified material. Because of this difference in material, a permanent connection could not be created during the welding process and a transmission fluid leak could develop between the transmission oil pipe and the flange. A loss of transmission fluid will result in oil marks on the ground beneath the vehicle and a warning lamp indicator, once the fluid goes beneath a certain level.
Dealers will correct the problem by inspecting the transmission oil pipe welds and replacing it as necessary. Volkswagen’s number for this recall is 38C7 and the NHTSA campaign number is 20V-272.
If you are the owner of a 2017-2018 Audi R8 Spyder or R8 Coupe, you may be receiving a manufacturer defect notice for the power train of your vehicle. According to the defect report filed with the NHTSA, during extreme maneuvers the transmission fluid could expand and foam up beyond the expansion volume in the gearbox, causing the transmission fluid to leak out of the gearbox ventilation hose. The fluid could contact hot engine parts, causing smoke and a possible fire.
Dealers will correct the problem by adding a double ventilation hose that has a higher oil expansion volume. Volkswagen’s number for this recall is 34J1 and the NHTSA campaign number is 18V-639.
Volkswagen will be contacting the owners of certain 2013-2015 Audi A8 and S8 vehicles because of a problem affecting the fuel system.
According to the NHTSA defect report, the high pressure fuel pump supply line could become porous and deteriorate from the inside. The resulting fuel leak may lead to a fuel smell withing the vehicle cabin and a potential fire in the presence of an ignition source.
Audi will be asking owners to return to their dealers to have the fuel line replaced. Volkswagen’s number for this recall is 20AV and the NHTSA campaign number is 18V-430.
Volkswagen will be contacting the owners of certain 2013-2016 Audi A4, A5 & Q5 vehicles regarding a problem affecting the electrical connector to the auxiliary heater. According to the defect report, the connector is susceptible to contact corrosion which may cause the auxiliary heater to fail and/or cause the wires to overheat and melt. The problem could result in an electrical fire.
Owners receiving notices will be asked to return to their dealers to have the auxiliary heater replaced, as necessary. Owners wanting more information about the problem can contact Audi customer service at 1-800-893-5298. Volkswagen’s numbers for this recall are 80C5 and 80C6 and the NHTSA campaign number is 17V-622.
Volkswagen will be asking the owners of certain 2017-2018 Audi A3 vehicles to return to their dealerships to correct a problem affecting the engine control unit (ECU). According to the defect report, the engine air/fuel mixture software is not robust enough. During engine start up or idling, the system may misinterpret the rotation of the dual mass flywheel as a knocking condition. The defect will result in loss of lose motive power when beginning to move from a stop or during a slow acceleration. Drivers will be alerted of a problem through an “Engine Stop While Driving” warning light.
Dealers will correct the problem by reprogramming the ECU software. For more information about the recall, owners may contact Audi customer service at 1-800-253-2834. Volkswagen’s number for this recall is 24DF the NHTSA campaign number is 17V-508.
Volkswagen will be contacting the owners of certain 2015-2017 Audi A7‘s because these vehicles may fail to comply with the Federal Motor Vehicle Safety Standard (FMVSS) for airbag deployment. According to the defect report filed with the NHTSA, a production error may have resulted in incorrect folding of the head curtain airbags. This could increase the risk of injury to passengers in the event of an accident.
Audi dealers will correct the problem by replacing the affected head curtain air bags. The recall is expected to begin June 29, 2017. Owners wanting more information about the problem are asked to contact Audi customer service at 1-800-253-2834. Volkswagen’s number for the recall is 69R2 and the NHTSA campaign number is 17V-293.
The owners of certain Audi vehicles equipped with 2.0L TFSI engines, will be contacted by the manufacturer regarding a problem affecting the engine and its cooling system. According to the defect report filed with the NHTSA, the coolant pump could become blocked by debris from the cooling system. If this happens the pump could overheat and cause a fire.
The vehicles affected by this defect include:
Audi has developed software which will deactivate the power supply to the coolant pump, if the pump becomes blocked. The driver will be notified of the blockage through an illuminated Malfunction Indicator Light (MIL). Owners wanting more information about the problem are asked to contact Audi customer service at 1-800-253-2834. Volkswagen’s number for this recall is 19M1 and the NHTSA campaign number is 17V-002.
