Checking the brake fluid level

  • Read the brake fluid level on the brake fluid reservoir fig. 182. The brake fluid level must be between the MIN and MAX markings .

The brake fluid level is monitored automatically.

Changing the brake fluid

Have the brake fluid changed regularly by an authorized Audi dealer or authorized Audi Service Facility.

WARNING

  • If the brake fluid level is below the MIN marking, it can impair the braking effect and driving safety, which increase the risk of an accident. Do not continue driving. See an authorized Audi dealer or authorized Audi Service Facility for assistance.
  • If the brake fluid is old, bubbles may form in the brake system during heavy braking.

    This would impair braking performance and driving safety, which increases the risk of an accident.

  • To ensure the brake system functions correctly, only use brake fluids that comply with VW standard 501 14 or FMVSS-116 DOT 4.

Note

  • If the brake fluid level is above the MAX marking, brake fluid may leak out over the edge of the reservoir and result in damage to the vehicle.
  • Do not get any brake fluid on the vehicle paint, because it will corrode the paint.
