ABS Control Module -J104- /ABS Hydraulic Unit -N55-: Installing
Install in reverse order of removal. Pay attention to the following:
Remove the plugs on the new ABS Hydraulic Unit -N55- only when installing the corresponding brake line.
If the plugs were already removed from the ABS Hydraulic Unit -N55-, brake fluid can leak; adequate filling and bleeding can no longer be guaranteed.
When installing the mount, make sure the rubber bushing does not push out of the bracket. Make sure the hydraulic unit is secure after installing it, otherwise malfunctions can occur.

-- Remove the Brake Pedal Actuator VAG1869/2.
-- Bleed the brake system. Refer to HYDRAULIC SYSTEM, BLEEDING .
Perform a basic setting on the Steering Angle Sensor -G85-, the Transverse Acceleration Sensor -G200- and the Brake Pressure Sensor 1 - G201- after installing the ABS Control Module -J104- and the ABS Hydraulic Unit -N55-.
