Control Module, Installing On Hydraulic Unit
Special tools and workshop equipment required
- Torque Screwdriver: VAG1624
- ESD Work Surface: VAS6613
- TORX® insert T25
Excessive shaking (for example, dropping, impact) may destroy the control module. The control module must then no longer be used.
- Surfaces must be cleaned before assembling.
-- Place the ABS Control Module -J104- on the ABS Hydraulic Unit -N55- without tilting it.
-- Tighten the ABS Hydraulic Unit -N55- and the ABS Control Module -J104- with the new TORX® bolts supplied to the tightening specification in two steps switching back and forth.
The ABS Hydraulic Unit -N55- threads for attaching the ABS Control Module -J104- may not be re-cut.
If the thread is damaged, the ABS Hydraulic Unit -N55- must be replaced.
If the bolts are difficult to install by hand or cannot be tightened to the tightening specification, then the thread is damaged.
Tightening Specification
A new ABS Control Module -J104- can be installed on an old ABS Hydraulic Unit -N55- a maximum of three times. This assures the elastic seal will not leak.
A used ABS Control Module -J104- may not be installed a second time.
