Audi E-Tron brake booster part can come apart
high How serious is it? About this label
Serious — Audi says this increases the risk of a crash, and while the notice does not tell owners to stop driving, you should get the repair done right away.
What's wrong, in plain English
A part inside the braking system — a rotor attached to a shaft — was not welded correctly at the factory. The two pieces can come apart while you drive. If that happens, the power assist that makes the brake pedal easy to press is reduced, and the anti-lock brakes and stability control stop working. You would have to push much harder on the pedal, and the car could be harder to control in a hard stop or on a slippery road.
What you should do
2. Call your Audi dealer to schedule the repair, or Audi customer service at 1-800-253-2834 with questions.
3. Have the dealer replace the brake booster — the repair is free.
