STARTER DOES NOT CRANK ENGINE
1) Ensure battery is fully charged. Make sure electrical and
ground connections are clean and tight. With ignition switch in START
position, measure voltage at spade terminal of starter solenoid.
Reading should be at least 8 volts (9.5 volts on Fox). If so, check
engine for mechanical problems. If voltage is not as specified, go to
next step.
2) Measure voltage at ignition switch. If reading is at least
8 volts (9.5 volts on Fox), check wiring between ignition switch and
starter solenoid. If voltage is not as specified, replace ignition
switch.
3) Measure voltage at field (starter) terminal of starter
solenoid. If reading is 8 volts or more, repair or replace starter. If
reading is less than 8 volts, replace starter solenoid.
NOTE: On vehicles with automatic transmission, also check
park/neutral switch.
STARTER CRANKS TOO SLOWLY
Ensure engine crankcase is filled with recommended viscosity
oil. Check charging system to ensure battery is fully charged. Make
sure electrical and ground connections are clean and tight. If starter
still turns slowly, repair or replace starter.
VOLTAGE DROP TEST
Starter Main Terminal
Connect a voltmeter between starter main terminal and starter
body. Disconnect ignition coil positive terminal and operate starter.
Voltage reading should not be more than 1.0 volt less than battery
voltage. If a larger voltage drop is indicated, circuit between
battery and starter terminal may be defective.
Main Starter Case
Connect a voltmeter between positive battery terminal and
starter motor "M" terminal. With ignition off, operate starter for 2-3
seconds. Battery voltage should be present, then drop to less than one
volt. If voltage is greater than specification, high resistance may be
present in circuit. Go to ACROSS SOLENOID SWITCH test.
Across Solenoid Switch
Connect a voltmeter between 2 starter solenoid terminal stud

6) Disconnect wires from starter solenoid. Remove lower
mounting nut, push up slightly on starter and remove. See Fig. 3. To
install, reverse removal procedure.Fig. 3: Removing Starter (Vanagon)

ALL MODELS EXCEPT VANAGON R & I
Removal & Installation
Disconnect negative battery cable. Support
engine/transmission assembly with Support Beam (VW 10-222). On all
models except Fox, add a Leg Set (VW 10-2224/1) to support beam. On
all models, remove engine mount bolts, nut, and clamp screw (next to
exhaust manifold flange). Remove engine mount. Disconnect wiring and
remove starter. To install, reverse removal procedure. See Fig. 4.Fig. 4: Removing Starter (Except Vanagon)

1989-92 SAFETY EQUIPMENT
Steering Column Switches
Cabriolet, Corrado, Fox,
Golf, GTI, Jetta, Passat
WARNING: To avoid injury from accidental air bag deployment, read and
carefully follow all WARNINGS and SERVICE PRECAUTIONS.
NOTE: For information on air bag DIAGNOSIS & TESTING or DISPOSAL
PROCEDURES, see the AIR BAGS article.
SERVICE PRECAUTIONS
Observe these precautions when working with air bag systems:
* DO NOT use computer memory saver tool. Using computer
memory tool will keep air bag system active and may
cause accidental deployment of air bag unit.
* Disable air bag system before servicing any air bag
system or steering column component. See DISABLING &
ACTIVATING AIR BAG SYSTEM.
* Because of critical operating requirements of system,
DO NOT attempt to service any air bag system component.
* Air bag parts should not be left unattended. They
should be installed in vehicle immediately after
obtaining them.
* Air bag components which have been dropped more than 18
inches should not be used.
* Chemical cleaners, oil and grease should not contact
vinyl covering on air bag unit.
* DO NOT place stickers or covers on steering wheel.
* Always disable air bag system before performing
electric welding on vehicle.
* Air bag system can only be tested using Diagnostic
Tester (VAG 1551) and Multimeter (US 1119). Never use
test light on air bag system.
* DO NOT expose air bag unit to temperatures greater than
194øF (90øC).
SYSTEM OPERATION CHECK
Two lights pertaining to air bag system are located directly
above air bag symbol in instrument cluster. See Fig. 1.
Control light is used to indicate readiness of system. This
light, which glows when ignition switch is turned to ON position or
engine is started, will stay on approximately 5-8 seconds while
diagnosis unit in air bag control unit performs an electronic test
cycle of system.

DESCRIPTION & OPERATION
System consists of a vane pump, rack and pinion steering
gear, and an oil reservoir. Vane pump draws fluid from reservoir and
supplies it to flow control valve. Control valve directs fluid to
appropriate side of rack piston.
LUBRICATION
CAPACITY
Fluid capacity is approximately 1 qt. (.95L).
FLUID TYPE
On all models, the recommended fluid type is V.W. Hydraulic
Oil (G 002 000).
FLUID LEVEL CHECK
Remove reservoir cover. Start engine and let idle. Fluid
level should be between MIN and MAX marks on reservoir.
HYDRAULIC SYSTEM BLEEDING
1) Start engine and let idle. Ensure fluid is at proper
level. Turn steering wheel from lock to lock several times quickly.
2) Continue until fluid level remains at reservoir mark.
Ensure no bubbles appear in reservoir when steering wheel is turned.
Shut off engine. Ensure oil level does not rise more than 3/8" (10
mm).
