Front wheel camber, adjusting Note: - Install special tool as shown in illustration and
slightly pre-tension.
- Loosen suspension strut/wheel bearing housing
connection.
- Adjust camber by turning the spindle to specified
setting.
- Tighten suspension strut/wheel bearing housing
connection.
- Check camber and if necessary, repeat
adjustment. Slight cant of tool is permitted. Do not move steering with tool in place! Before adjusting camber, it is essential to
examine all suspension components for damage
(visual inspection) and to replace any damaged
parts. Because bolts with a shank diameter of 11 mm
diameter have been installed as standard it is no
longer necessary to replace bolts to correct
camber. Page 6 of 7Vehicle alignment12/7/2004http://ebahn.bentleypublishers.com/vw/servlet/Display?action=Goto&type=repair&id=VW.B4.SU01.44.1

Calculating the direction of travel:

- If both toe figures have the same preceding sign
(+/+ or -/-), subtract the smaller figure from the
larger figure and divide by 2 Example.
Left rear wheel
toe
Right rear wheel
toe
+ 15' + 5'
15' - 5' =
10'
10' : 2 = 5'
Deviation from direction of travel = 5'

- Add figures with different sign (+/-) and divide by 2 Example.
Left rear wheel
toe
Right rear wheel
toe
+ 15' - 5'
15' + 5' =
20'
20' : 2 =
10'
Deviation from direction of travel = 10'
The individual result is the actual alignment
deviation from the vehicle longitudinal axis. Page 7 of 7Vehicle alignment12/7/2004http://ebahn.bentleypublishers.com/vw/servlet/Display?action=Goto&type=repair&id=VW.B4.SU01.44.1

Anti-locking Brake System
(ABS) and Anti-locking Brake
System with Electronic
Differential Lock (ABS/EDL)
Teves 04
The ABS, ABS/EDL brake system is divided
diagonally. The servo-assist is effected
pneumatically, by the vacuum brake servo unit.
Located between the brake master cylinder and
the vacuum servo unit is a mounting bracket for
the hydraulic unit with pump.
The hydraulic unit together with pump, supplies
only the anti-locking brake system (ABS) or anti-
locking brake system and traction control system
(ABS/EDL).
Malfunctions on the ABS, ABS/EDL systems do
not influence the brake system and servo. The
vehicle can be driven without the ABS, ABS/EDL
functions operating. Page 1 of 5Anti-locking Brake System (ABS) and Anti-locking Brake System with Electronic Differential Lock (A...12/7/2004http://ebahn.bentleypublishers.com/vw/servlet/Display?action=Goto&type=repair&id=VW.B4.SU01.45.1

Notes for repair work on ABS, ABS/EDL
Before doing any repair work on the anti-locking system, determine the cause of the malfunction
using On Board Diagnostic (OBD).
Repair Manual, Brake System On Board Diagnostic (OBD), Repair Group 01 Before working on the ABS, ABS/EDL system,
disconnect the battery Ground strap. On
vehicles with coded radio, obtain cooling.
When working with brake fluid, observe the
relevant safety precautions and notes Page 47-27 . After work for which the brake system had to be opened, bleed the brake system with brake filler and bleeder unit VAS 5234 Page 47-27 . During the final road test, make sure that a
controlled brake test is performed at least once
(pulsations must be felt at the brake pedal).
Absolute cleanliness is required when working
on the anti-locking brake system; it is not
permitted to use any products which contain
mineral oils, such as oils, greases etc. Page 2 of 5Anti-locking Brake System (ABS) and Anti-locking Brake System with Electronic Differential Lock (A...12/7/2004http://ebahn.bentleypublishers.com/vw/servlet/Display?action=Goto&type=repair&id=VW.B4.SU01.45.1

Thoroughly clean all unions and the adjacent
areas before loosening, do not use aggressive
cleaning agents such as brake cleaner, petrol,
thinners or similar.
Place removed parts on a clean surface and
cover.
Do not use fluffy cloth. Carefully cover or seal open components if
repairs cannot be carried out immediately.
Only remove replacement parts from packaging
immediately prior to installation.
Only use genuine packed parts. When the system is open do not work with
compressed air and do not move the vehicle.
Make sure that no brake fluid enters harness
connectors.
During painting operations, the electronic
control module can be exposed to a max.
temperature of 95C (203F) for only a short
period, and to a maximum of 85C (185F) for
longer periods (approx. 2 hours). Page 3 of 5Anti-locking Brake System (ABS) and Anti-locking Brake System with Electronic Differential Lock (A...12/7/2004http://ebahn.bentleypublishers.com/vw/servlet/Display?action=Goto&type=repair&id=VW.B4.SU01.45.1
