What's wrong, in plain English
Some of these Audi vehicles may have a brake fluid reservoir cap that was installed with the wrong label. Because the cap's label does not match what should be used, it is possible for the wrong type of brake fluid to end up in the vehicle. Using the incorrect brake fluid can reduce how well the brakes work, making the vehicle less able to slow down or come to a stop when needed.
What you should do
2. Contact an Audi dealer, or call Audi customer service at 1-800-253-2834, to have the brake fluid cap inspected.
3. Any necessary replacement will be done free of charge.
Where do I find my VIN, and what do I tell the dealer?
