The brake caliper pistons on these vehicles may have insufficient coating, potentially reducing the brake performance.
A reduction of braking performance can increase the risk of a crash.
Owners are advised not to drive their vehicles until the brake system has been checked.
What to do
Volkswagen and Audi will notify their owners.
Audi dealers will bleed the rear brakes. Volkswagen dealers will inspect the brake system and as necessary, bleed the front brakes (Atlas models only) or bleed the rear brakes (all other Volkswagen models).
The recall is expected to begin before July 31, 2018.
Owners may contact Volkswagen customer service at 1-800-893-5298 and Audi customer service at 1-800-253-2834. Volkswagen's numbers for this recall are 47N8, 47N9, and 47N6.
