MK8 Anti-lock Brake System (ABS)
The MK8 ABS is similar to the MK5.7 in construction and design. The main differences are:
- New ABS control unit.
- New hydraulic lines through a revised valve block.
- New wiring harness and electrical connector.
The MK8 ABS system will be installed from 08/2004 in vehicles which only have the ABS function.
Vehicles with ESP/Brake Traction Control System (BTCS) will continue to be equipped with the MK5.7 ABS system.
