Recall 90S9 Gateway Control Module – 2021-2022 Audi Q5 & SQ5

SEOCONTENT-START

NAME Title Department Phone Fax Date Dear Mr. Owens: Volkswagen hereby submits the following chronology associated with the subject recall. Chronology of Defect August 2020: Audi receives an inquiry from the Chinese authority regarding gateway control module failures due to liquid ingress. At that point the issue was unknown to Audi so far. Investigation regarding root cause and special circumstances commenced. It was found that all cases in China occurred due to a liquid spill on the rear seat bench. August 2020 – February 2021: The analysis revealed that in case of a liquid ingress, the gateway control module goes into a failsafe mode as part of the safety concept in order to avoid unwanted vehicle reactions. 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. As part of the investigation, a potential solution for the field and in production was tasked, developed and tested. 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. This was confirmed by the field situation at the time. 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 field worldwide regarding this topic. March 2021: The North American region reported an increase in customer reports related to a gateway control module failure on Q5 vehicles after a liquid spill. March 2021 – September 2021: Audi conducted additional testing regarding the impacts of a liquid ingress 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 potential additional 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 impact of this additional potential James C.

Audi also noticed an increased number of VOQ´s and decided to discuss the topic with NHTSA ODI during the company´s Quarterly Meeting in September 2021. October 2021: The Audi Product Safety Committee decided 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. Audi started to prepare the necessary steps for the launch of the service campaign. November 2021: Audi meets with Transport Canada and the Defective Product Administrative Center in China to discuss the topic based on customer complaints in those markets. Both agencies voiced concerns that a shutdown of the gateway control module due to liquid ingress may happen suddenly and the behavior may be perceived as a loss of mobility. December 01, 2021: The position of the Canadian and Chinese authority was presented to the Audi Product Safety Committee and the existing decision was re-evaluated. Based on the foregoing, Audi decided to conduct a voluntary recall to remedy affected vehicles. Date of determination: December 1, 2021. Audi is not aware of any crashes or injuries due to this issue. Please contact me if you require any additional information or have any questions related to this information.

Elsa is the only valid campaign inquiry & verification source.  Campaign status must show “open.”  If Elsa shows other open action(s), inform your customer so that the work can also be completed at the same time the vehicle is in the workshop for this campaign. Problem Description If liquid reaches and enters the gateway control module, mostly due to a liquid spill on the rear seats, it is being switched off as part of the safety concept. In very rare cases (such as when driving through heavy rain or deep water) there may also be water ingress through an insufficient underbody seam. Water/liquid ingress into the gateway control module may lead to various internal errors due to short circuits within the control unit. The gateway control module has a safety concept in case implausible signals are detected in the control unit. If such implausible signals are detected, the gateway switches off its function in order to avoid unwanted vehicle reactions. The vehicle remains steerable and the brake system is fully operable. The engine goes into emergency mode and remains in operation with reduced power. Unexpected reduced engine power may create an increased risk of a crash in certain driving situations. Corrective Action Install a protective cover for the gateway control module which will protect the part from liquid ingress. In addition, on vehicles produced until end of August 2021, the dealer will also seal the insufficient underbody seam. Precautions Several warning messages will appear if the gateway control module shuts down. The error messages occur due to the interrupted communication between several systems. Even though several systems are displaying a malfunction, not all of these systems are impacted. Customers seeing error messages are advised to make arrangements to have the vehicle diagnosed/repaired by an authorized Audi dealer without delay.

March 2022 90S9 Page 1 of 19 Safety Recall Code: 90S9 REVISION Subject Gateway Control Module Release Date March 23, 2022 REVISION SUMMARY Updated requirements for contacting Audi Warranty in the event a gateway control module is damaged Affected Vehicles Country Beginning Model Year Ending Model Year Vehicle Vehicle Count USA 2018 2022 Q5 251,971 USA 2018 2022 SQ5 37,020 CAN 2018 2022 Q5 41,214 CAN 2018 2022 SQ5 6,932 Check Campaigns/Actions screen in Elsa on the day of repair to verify that a VIN qualifies for repair under this action. Elsa is the only valid campaign inquiry & verification source.  Campaign status must show “open.”  If Elsa shows other open action(s), inform your customer so that the work can also be completed at the same time the vehicle is in the workshop for this campaign. Problem Description If liquid reaches and enters the gateway control module, mostly due to a liquid spill on the rear seats, it is being switched off as part of the safety concept. In very rare cases (such as when driving through heavy rain or deep water) there may also be water ingress through an insufficient underbody seam. Water/liquid ingress into the gateway control module may lead to various internal errors due to short circuits within the control unit. The gateway control module has a safety concept in case implausible signals are detected in the control unit. If such implausible signals are detected, the gateway switches off its function in order to avoid unwanted vehicle reactions. The vehicle remains steerable and the brake system is fully operable. The engine goes into emergency mode and remains in operation with reduced power. Unexpected reduced engine power may create an increased risk of a crash in certain driving situations. Corrective Action Install a protective cover for the gateway control module which will protect the part from liquid ingress. In addition, on vehicles produced until end of August 2021, the dealer will also seal the insufficient underbody seam. Precautions Several warning messages will appear if the gateway control module shuts down. The error messages occur due to the interrupted communication between several systems. Even though several systems are displaying a malfunction, not all of these systems are impacted. Customers seeing error messages are advised to make arrangements to have the vehicle diagnosed/repaired by an authorized Audi dealer without delay. Code Visibility On or about January 18, 2022, the campaign code was applied to affected vehicles. Owner Notification Owner notification took place in January 2022.

Elsa is the only valid campaign inquiry & verification source.  Campaign status must show “open.”  If Elsa shows other open action(s), inform your customer so that the work can also be completed at the same time the vehicle is in the workshop for this campaign. Problem Description If liquid reaches and enters the gateway control module, mostly due to a liquid spill on the rear seats, it is being switched off as part of the safety concept. In very rare cases (such as when driving through heavy rain or deep water) there may also be water ingress through an insufficient underbody seam. Water/liquid ingress into the gateway control module may lead to various internal errors due to short circuits within the control unit. The gateway control module has a safety concept in case implausible signals are detected in the control unit. If such implausible signals are detected, the gateway switches off its function in order to avoid unwanted vehicle reactions. The vehicle remains steerable and the brake system is fully operable. The engine goes into emergency mode and remains in operation with reduced power. Unexpected reduced engine power may create an increased risk of a crash in certain driving situations. Corrective Action Install a protective cover for the gateway control module which will protect the part from liquid ingress. In addition, on vehicles produced until end of August 2021, the dealer will also seal the insufficient underbody seam. Precautions Several warning messages will appear if the gateway control module shuts down. The error messages occur due to the interrupted communication between several systems. Even though several systems are displaying a malfunction, not all of these systems are impacted. Customers seeing error messages are advised to make arrangements to have the vehicle diagnosed/repaired by an authorized Audi dealer without delay. Code Visibility On or about January 18, 2022, the campaign code was applied to affected vehicles. Owner Notification Owner notification took place in January 2022.

90S9 USA IMPORTANT SAFETY RECALL <MONTH YEAR> <CUSTOMER NAME> <CUSTOMER ADDRESS> <CUSTOMER CITY STATE ZIPCODE> This notice applies to your vehicle: <MODEL YEAR> <BRAND> <CARLINE>, <VIN> NHTSA: 21V947 Subject: Safety Recall 90S9 – Gateway Control Module Dear Audi Owner, This notice is sent to you in accordance with the National Traffic and Motor Vehicle Safety Act. Audi has decided that a defect, which relates to motor vehicle safety, exists in certain 2018- 2022 model year Audi vehicles. Our records show that you are the owner of a vehicle affected by this action. What is the issue? If liquid reaches and enters the gateway control module, mostly due to a liquid spill on the rear seats, it is being switched off as part of the safety concept. In very rare cases (such as when driving through heavy rain or deep water) there may also be water ingress through an insufficient underbody seam. Water/liquid ingress into the gateway control module may lead to various internal errors due to short circuits within the control unit. The gateway control module has a safety concept in case implausible signals are detected in the control unit. If such implausible signals are detected, the gateway switches off its function in order to avoid unwanted vehicle reactions. The vehicle remains steerable and the brake system is fully operable. The engine goes into emergency mode and remains in operation with reduced power. Unexpected reduced engine power may create an increased risk of a crash in certain driving situations. What will we do? To correct this defect, your authorized Audi dealer will install a protective cover for the gateway control module, which will protect the part from liquid ingress. In addition, on vehicles produced until end of August 2021, the dealer will also seal the insufficient underbody seam. This work will take about an hour to complete and will be performed for you free of charge. Please keep in mind that your dealer may need additional time for the preparation of the repair, as well as to accommodate their daily workshop schedule. What should you do? Please contact your authorized Audi dealer without delay to schedule this recall repair. For your convenience, you can also visit www.audiusa.com and click on the “Find a Dealer” link to locate a dealer near you and schedule this service. Audi of America, Inc. 3800 Hamlin Road Auburn Hills, MI 48326 +1 800 253 2834 www.audiusa.com Audi of America, Inc. IMPORTANT SAFETY RECALL Precautions you should take Several warning messages will appear if the gateway control module shuts down. The error messages occur due to the interrupted communication between several systems. Even though several systems are displaying a malfunction, not all of these systems are impacted. Customers seeing error messages are advised to make arrangements to have the vehicle diagnosed/repaired by an authorized Audi dealer without delay. Lease vehicles and address changes If you are the lessor and registered owner of the vehicle identified in this action, the law requires you to forward this letter immediately via first-class mail to the lessee within ten (10) days of receipt. If you have changed your address or sold the vehicle, please fill out the enclosed prepaid Owner Reply card and mail it to us so we can update our records. Can we assist you further? If your authorized Audi dealer fails or is unable to complete this work free of charge within a reasonable time, please contact Audi Customer Experience at 1-800-253-2834 or via our “Contact Us” page at www.audiusa.com.

Sincerely, Audi Customer Protection 90S9 USA IMPORTANTE LLAMADO A REVISIÓN POR SEGURIDAD <MES AÑO> <NOMBRE DEL CLIENTE> <DIRECCIÓN DEL CLIENTE> <CIUDAD, ESTADO Y CÓDIGO POSTAL DEL CLIENTE> Este aviso se aplica a su vehículo: <MODELO> <MARCA> <LÍNEA>, <VIN> Administración Nacional de Seguridad del Tráfico en las Carreteras (NHTSA): 21V947 Asunto: Llamado a revisión por seguridad 90S9 – Módulo de control de la puerta de enlace Estimado propietario de un Audi: Le enviamos este aviso de conformidad con la Ley Nacional de Seguridad del Tráfico y Vehículos Motorizados. Audi determinó que hay un defecto relacionado con la seguridad de los vehículos motorizados en ciertos vehículos Audi modelo 2018-2022. Nuestros registros muestran que usted es propietario de un vehículo afectado por esta acción. ¿Cuál es el problema? Si algún líquido llega al módulo de control de la puerta de enlace y entra en él, principalmente debido a que se haya derramado en los asientos traseros, el módulo se apagará como parte del plan de seguridad. En casos muy raros (por ejemplo, al conducir con lluvia intensa o en encharcamientos profundos) el agua también puede entrar por las uniones en la parte inferior de la carrocería si no están bien selladas. Si el agua o algún líquido entra en el módulo de control de la puerta de enlace, puede haber varios errores internos debido a cortocircuitos dentro de la unidad de control. El módulo de control de la puerta de enlace tiene un plan de seguridad en caso de que se detecten señales inverosímiles en la unidad de control. Si se detectan tales señales inverosímiles, la puerta de enlace dejará de funcionar para evitar reacciones no deseadas del vehículo. El sistema de frenos funcionará sin ningún problema y la dirección del vehículo no se verá afectada. El motor entrará en modo de emergencia y seguirá funcionando con potencia reducida. La reducción inesperada en la potencia del motor puede llevar a un mayor riesgo de un choque en ciertas situaciones de manejo. ¿Qué vamos a hacer? Para corregir este defecto, su concesionaria autorizada Audi instalará una cubierta protectora para el módulo de control de la puerta de enlace para que no entre ningún líquido. Además, en los vehículos fabricados hasta finales de agosto de 2021, la concesionaria también sellará las uniones de la parte inferior de la carrocería. Este trabajo tomará aproximadamente una hora y se realizará de forma gratuita. Tenga en cuenta que su concesionaria puede necesitar más tiempo para preparar la reparación, así como para adaptar el cronograma diario del taller. Audi of America, Inc. 3800 Hamlin Road Auburn Hills, MI 48326 +1 800 253 2834 www.audiusa.com Audi of America, Inc. IMPORTANTE LLAMADO A REVISIÓN POR SEGURIDAD ¿Qué debe hacer usted? Comuníquese de inmediato con su concesionaria autorizada Audi para programar esta reparación por llamado a revisión. Para su comodidad, también puede visitar www.audiusa.com y hacer clic en el enlace “Buscar una concesionaria” para ubicar una concesionaria cerca de usted y programar este servicio. ¿Qué precauciones debe tomar? Si el módulo de control de la puerta de enlace se apaga, aparecerán varios mensajes de advertencia. Los mensajes de error ocurren porque se interrumpe la comunicación entre diferentes sistemas. Aunque varios sistemas muestren un mal funcionamiento, esto no quiere decir que todos ellos hayan sufrido afectaciones. Se recomienda que los clientes que vean mensajes de error se comuniquen con una concesionaria Audi autorizada de inmediato para programar el diagnóstico o la reparación del vehículo. Vehículos en arrendamiento y cambios de dirección Si usted es el arrendador y propietario registrado del vehículo que se identifica en esta acción, la ley requiere que le reenvíe esta carta inmediatamente por first-class mail al arrendatario en un plazo de diez (10) días a partir de que la reciba. Si cambió de dirección o vendió el vehículo, llene la tarjeta prepagada de respuesta del propietario que se adjunta a esta carta y envíenosla por correo para poder actualizar nuestros registros. ¿Hay algo más en lo que le podamos ayudar? Si su concesionaria autorizada de Audi no logra o no puede completar este trabajo de forma gratuita en un plazo razonable, comuníquese con el área de Experiencia del cliente de Audi al 1-800-253-2834 o mediante nuestra página “Contáctenos” en www.audiusa.com.

In very rare cases (such as when driving through heavy rain or deep water) there may also be water ingress through an insufficient underbody seam. Water/ liquid ingress into the gateway control module may lead to various internal errors due to short circuits within the control unit. The gateway control module has a safety concept in case implausible signals are detected in the control unit. If such implausible signals are detected, the gateway switches off its function in order to avoid unwanted vehicle reactions. The vehicle remains steerable and the brake system is fully operable. The engine goes into emergency mode and remains in operation with reduced power. FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : If liquid reaches and enters the gateway control module, it is being switched off as part of the safety concept. The vehicle remains steerable and the brake system is fully operable. The engine goes into emergency mode and remains in operation with reduced power. Unexpected reduced engine power may create an increased risk of an accident in certain driving situations. Description of the Cause : The vast majority of cases known to have occurred were due to a liquid spill on Part 573 Safety Recall Report 21V-947 Page 3 The information contained in this report was submitted pursuant to 49 CFR §573 the rear seats of the vehicle. In a very small amount of cases, water entered the vehicle from underneath when driving through heavy rain and/or deep puddles due to an insufficient underbody seam. Identification of Any Warning that can Occur : Several warning messages will appear if the gateway control module shuts down. The error messages occur due to the interrupted communication between several systems. Even though several systems are displaying a malfunction, not all of these systems are impacted. Involved Components : Component Name 1 : Protective cover Component Description : Protective cover for gateway control module Component Part Number : 80A 907 577 C Supplier Identification : Component Manufacturer Name : AUDI AG Address : NR Ingolstadt Foreign States 85045 Country : Germany Chronology : Chronology provided under separate cover due to space limitations in NHTSA portal. Description of Remedy : Description of Remedy Program : At no cost to customers, Audi dealers will install a protective cover for the gateway control module which will protect the part from liquid ingress. In addition, on vehicles produced until end of August 2021, the dealer will also seal the insufficient underbody seam. Audi will not offer a reimbursement program under this recall. How Remedy Component Differs from Recalled Component : No parts are being replaced. The dealer will install a protective cover for the gateway control module and apply a sealant to seal the underbody and prevent water ingress from underneath. Part 573 Safety Recall Report 21V-947 Page 4 The information contained in this report was submitted pursuant to 49 CFR §573 Identify How/When Recall Condition was Corrected in Production : Underbody seam: The robot applying the sealant bead was reprogrammed on August 28, 2021 in the factory in Mexico. Protective cover: Starting on November 12, 2021 all vehicles produced have been equipped with the protective cover for the gateway control module.
