Removing and installing/replacing hydraulic
unit for DSC (M57 / M57T2 / M47T2)

Read and comply with General Information.

Before removing hydraulic unit, read out control unit fault memory
and if necessary print out diagnostic trouble code.

After completing work: Bleed braking system

Installation:

When replacing the control unit, carry out the following tasks with
the DIS (Diagnosis and Information System):

Vehicle coding (performed by the vehicle itself)

Adjustment of steering angle sensor (performed by the

vehicle itself)

Adjustment of brake pressure sensor (performed by the

vehicle itself)

Adjustment of lateral acceleration sensors (performed by the

vehicle itself)

Mix-up check of brake lines

Function check, hydraulic unit

Press clutch pedal down to floor and secure with pedal support.

Note:

The pedal support may only be released when the brake lines are
reconnected.

This prevents brake fluid from emerging from the expansion tank
and air from entering the system when the brake lines are opened.

Disconnect plug connection (1).

Release nuts (2) and place pressure transducer to one side.
