If the above fault occurs, it may be associated with the brake lining wear indicator. When applying light braking force, the thermal contact on the brake disk may drag, thereby causing an unpleasant squeal. In this case, the thermal contacts must be checked and, if required, replaced with the new versions.
OE part number: front thermal contact 34356778037
rear thermal contact 34356778038
Brake lining thermal contact, front axle: 8DK 355 250-201
Brake lining thermal contact, rear axle: 8DK 355 250-531
In this case, it is advisable to check the brake disks and brake linings for wear and, if necessary, replace them.
