Abs Control Module And Abs Hydraulic Unit, Removing And Installing: Installing
Install in reverse order of removal. Note the following:
Only remove the plugs on the new hydraulic unit if the corresponding brake line is installed.
If the plugs are removed too early from the hydraulic unit, brake fluid can escape and the unit may not be sufficiently filled or adequately bled.
When installing the hydraulic unit, make sure the damper rubber is not pushed out of the bracket.
-- Install the brake lines carefully with the :VAG1410/8 .
Brake Line Tightening Sequence:
-- Remove the :VAG1869/2 .
-- Bleed the brake system. Refer to HYDRAULIC SYSTEM, STANDARD BLEEDING .
-- Code the radio.
-- Code the ABS Control Module -J104- using the Vehicle Diagnostic Tester.
While doing so, a basic setting for the Steering Angle Sensor -G85-, Transverse Acceleration Sensor -G200-, Longitudinal Acceleration Sensor -G251- and Brake Pressure Sensor 1 -G201- must be performed.
