Removing
Caution
There is a risk of contamination from escaping hydraulic fluid.
The battery must be disconnected as the hydraulic pump starts up even with the ignition switched off.
When disconnecting the battery there is a risk of serious damage to electronic components:
Observe the correct procedure for disconnecting the battery.
–
Disconnect the earth wire at the battery
→ Rep. gr.27
.
–
Wash outside of bonnet and dry with a chamois leather.
–
Release service flap from inside.
–
Release bonnet
-arrows-
and pull it forwards slightly.
–
Fit the protective cover -VAS 6011- over the bonnet.
Note
Do not store the bonnet in an upright position.
–
Detach the bonnet and set it down on the protective cover -VAS 6011-.
–
Unfasten the pressure accumulator by roughly
1
/
2
a turn.
l
The hydraulic fluid level in the reservoir increases.
–
Remove the bolt
-1-
at the top of the gear actuator heat shield
-2-
.
–
Use a screwdriver to prise the hose/pipe assembly clip out of the gear actuator.
–
Pull the hose/pipe assembly
-1-
and
-2-
out of the gear actuator.
–
Seal off open lines and connections with clean plugs from engine bung set -VAS 6122-.
–
Unplug the connector
-3-
at the vehicle speed sender -G68-.
–
For re-installation, mark
-arrows A, B-
the connectors for the valves
-2-
and
-4-
.
–
Unplug electrical connectors at valves
-1 … 4-
.
–
Remove the noise insulation
-arrows-
.
–
Unscrew the right drive shaft heat shield
-arrow-
.
–
Remove the bolts
-3-
and detach the gear actuator heat shield
-2-
.
–
Unplug the connectors
-1-
and
-2-
at the gear detector potentiometers -G239-/-G240-.
–
Disengage
-arrows-
wiring harness from fasteners at gear actuator and move clear.
–

.
–
Attach the wiring harness to the gear actuator
-arrows-
.
–
Plug in the connectors
-1-
and
-2-
at the gear detector potentiometers -G239-/-G240-, paying attention to the different wire lengths.
t
Long wire for gear detector potentiometer 1 -G239-.
t
Short wire for gear detector potentiometer 2 -G240-.
–
Use the current flow diagram to check wiring and connectors
→ Current flow diagrams, Electrical fault finding and Fitting locations
.
–
Install noise insulation
→ Rep. gr.50
.
–
Fit the connectors in line with the marks
-arrows A, B-
made on removal.
1 -
Connector for selector lever valve 1 -N284-

Caution
There is a risk of damage to the gear actuator.
t
Make sure the hose/pipe assemblies are fitted in accordance with the coloured marks
→ Fig.
.
t
If the hose/pipe assemblies have been incorrectly inserted, there is a risk of irreparable damage to the gear actuator on connecting the battery.
–
Plug in the connector at the vehicle speed sender -G68-.
–
Secure the pressure accumulator
→ Chapter
.
–
Observe correct procedure after connecting battery
→ Rep. gr.27
.
–
Switch on ignition (hydraulic fluid level in reservoir falls).
–
Perform a visual check for leaks in the hydraulic system.
–
Check the fluid level in the reservoir for the clutch mechanism and selector mechanism and replenish the fluid
