New Control Module, Installing
Excessive shaking (for example dropping, impact) may destroy the control module. Control module must then no longer be used.
- Before new control module can be assembled, pump motor adapter must first be inserted until it stops and engages. Adapter guide must not be damaged.
- The adapter supplied as replacement part for control module can be engage only once and then must not be separated again.
- The white grouting compound on base of control module serves as a seal and must not be removed.
- All contact surfaces on adapter, pressure sensor and control module as well as silicon gel and sealing elements must not be touched by hand or objects, soiled or damaged.
-- Press adapter into adapter guide until it stops, it must then be engaged.
-- Place control module without canting it onto hydraulic unit.
-- Bolt hydraulic unit and control module with new TORX® bolts supplied.
A new control module may be installed a max. of two times to a used hydraulic unit, to ensure that the elastic gasket seals sufficiently.
Do not install a used control module.
Control Module and Hydraulic Unit, Installing
Do not remove sealing plugs at new hydraulic unit until the corresponding brake line is about to be installed.
If the sealing plugs are removed too early, brake fluid can escape. If this occurs, unit may not be sufficiently filled or adequately bled.
-- Install in reverse order of removal.
-- Remove V.A.G 1869/2.
-- Bleed brake system, refer to BRAKE SYSTEM, BLEEDING
-- Enter radio code.
-- Code the ABS Control Module -J104- with the vehicle diagnostic tester in "Guided Fault Finding".
A steering angle sensor -G85-, transverse acceleration sensor -G200- and brake pressure sensor 1 -G201- basic setting must be done.
