Memory Keeper Device
- 2Release the hood lever, located in the passenger compartment.
- 3Pull the hood release cable toward you and raise the engine hood.
- 4Using a 10mm nutdriver or 1/4-inch 10mm square drive socket and 1/4-inch square drive ratchet,remove three (3) nuts that secures the top engine cover.
Removing nuts to top engine cover
- 5Remove the vacuum hose attached to bracket at back of top engine cover.
- 6Remove the oil dip stick, top engine cover, and set aside.
- 7Using a 10mm nutdriver or combination wrench, remove the cable to the negative post of the cranking battery.
- 8Remove the cable to the positive post of the battery.
- 9Remove the bolt that secures the battery hold down bracket.
- 10Remove the cranking battery from the Beetle TDI.
- 11Remove the bolts securing the battery tray to the vehicle body.
- 12Remove the battery tray from the Beetle TDI.
Removing Battery Tray
- 13Remove the battery B+ cable to the starter motor.
- 14Using a creeper on wheels, position the body (driver-side) underneath the vehicle.
- 15Using a 3/8-inch square drive 18mm socket and a 3/8-inch square drive ratchet, remove two (2) bolts securing the starter to the engine block.
- 16Tilt the starter motor, with the hands, and remove from top of the engine.
Tilt the starter motor with your hands.
- 17Bench test the starter motor to confirm that the starter is defective.
Bench Testing Starter Motor
- 18Place the positive (red) cable of a battery booster pack on the B+ terminal of the starter.
Connecting Positive Cable of Battery pack to Starter Terminal
- 19Position one (1) lead of the jumper wire to the low-voltage exciter terminal of the starter.
- 20Touch the other lead of jumper wire to the B+ terminal of the starter.
- 21Clean the negative and positive battery posts with a post cleaning brush.
- 22Clean corrosion deposits on the battery cables(negative and positive) with sandpaper.
Cleaning Battery Cables
- 23Position the replacement starter motor on the engine block.
- 24Install the two (2) bolts securing the starter to the engine block.

Tips
- In Step 21, the starter motor is good if the solenoid will lift and energize the starter pinion. It should spin at roughly 150 to 200rpm's.
- Two (2) tests should be made to fully check the conditon of the starter motor. The above test is termed a no-load test. It is tested on the bench out of the vehicle. The second test is a load test. The test is made with the starter installed in the vehicle. Both tests require the use of the battery booster pack.
- Before installing battery cables, coat the negative and positive battery posts with Vaseline to prevent corrosion.
- In Step 26, make sure that the starter pinion engages the teeth on the flywheel when installing the starter motor.
Warnings
- Negligence working around the battery can cause "arcing" resulting in internal damage to an electronic component.
- To prevent "arcing", remove the negative cable first followed by the positive cable.
