CAUSE
Microscopic movement of the contact interface between the inner brake disc and the wheel bearing flange on vehicles equipped with lightweight brake discs.
CORRECTION
Remove both front brake discs and install a friction ring between the brake disc and the wheel bearing flange.
PROCEDURE
For conditions that are similar to the situation as heard in the video:
- Verify that the noise is produced when cornering without the brakes applied.
- Check which type of brake discs are installed on the vehicle.
Are the lightweight discs (shown at right in the photo) installed on the vehicle?
Yes - Go to step 3
No - Continue diagnosis
- Remove the brake discs according to repair instructions 34 11 220 "Removing and installing/replacing both front brake discs".
- Clean the wheel bearing flange with brake cleaner.
- Install the "friction ring" on wheel bearing flange as shown.
- Reinstall all removed parts according to repair instruction 34 11 220 "Removing and installing/replacing both front brake discs".
- Repeat the procedure for the opposite front wheel.NOTE: If the vehicle is older than 24 months from production date, replace the wheel bolts on the front and rear axle.
