Hydraulic Control Assembly - Antilock Brakes: Service and Repair
Removing and Installing/Replacing Control Unit

34 52 515 - Removing and installing/replacing control unit

Necessary preliminary tasks:

-

Remove hydraulic unit

When replacing control unit:

-

Carry out programming/coding See: Testing and Inspection/Programming and Relearning/Vehicle Programming and Coding

-

Adjustment of steering angle sensor

-

Mix-up check of brake lines

-

Function check, hydraulic unit

To remove the hydraulic unit, close off the brake line connections with the plugs (1) contained in the control unit repair kit.

This prevents brake fluid from escaping from the hydraulic unit, which in turn facilitates the subsequent bleed of the brake system.

Important!

Secure pump motor with retaining tab (2) and plug (3) from control unit repair kit on valve block.

Pump motor and valve block must not be separated!
