The problem: A spill in the rear seat or water from an insufficient body seam underneath the vehicle may allow liquid to penetrate the gateway control module, causing it to shut down and reduce engine power.
The fix: Audi dealerships will install a protective cover for the gateway control module, which will protect the part from liquid. In addition, on vehicles produced until the end of August 2021, the dealership will seal an insufficient underbody seam. Audi will not offer a reimbursement program under this recall.
How to contact the manufacturer: Owners may contact Audi customer service at 800-253-2834.
NHTSA campaign number: 21V947000. Audi’s number for this recall is 90S9.
Check to see whether your vehicle has an open recall. NHTSA’s website will tell you whether your vehicle has any recalls that need to be addressed.
If you plug your car’s 17-digit vehicle identification number (VIN) into NHTSA’s website and a recall doesn’t appear, it means your vehicle doesn’t currently have one. Because automakers issue recalls often, and for many older vehicles, we recommend checking back regularly.
