Service
Install the new ground wire from the coil connector to Ground 12 under the battery as follows:

Note: When working with batteries, always review Cautions and Warnings in: Repair Group 27, Battery, General information; “Vehicle batteries” in Owner Manual, Tips and Advice; or Remove battery (see Repair Group 27, Battery, Removing and installing, for the appropriate model).

Golf, Jetta:
– Locate and remove the terminal from coil
connector T6d/1 (see appropriate wiring diagram if necessary).
– Terminate this wire by neatly taping it to the
existing wire harness (do not cut the wire).

New Beetle:
– Locate and remove the terminal from coil
connector T6a/1 (see appropriate wiring diagram if necessary).
– Terminate this wire by neatly taping it to the existing wire harness (do not cut the wire).

Golf, Jetta, New Beetle:
– Cut repair wire 000 979 225 to 22” (558.8 mm)
and install the new seal; then slide the seal near the terminal, see Required Parts & Tools.
– Cut repair wire 000 979 230 to 12” (304.8 mm).
– Splice the repair wires together using the butt splice. Do not substitute any other wires when making and assembling the repair wire.
– When finished, the correct repair wire length should be 34” (863.6 mm).
– Heat the butt splice using a heat gun from the Repair Kit noted in Required Parts & Tools.

Golf, Jetta:
– Insert the terminal into cavity T6d/1 of the coil connector.

For New Beetle:
– Insert the terminal into cavity T6a/1 of the coil connector.

Golf, Jetta:
– Remove the cap nut from stud GND 12 under the battery tray.

See Figure 1.Figure 2

– The ground terminals, cap nut and stud should be clean and free of paint or corrosion.
– Route the new ground wire along the existing harness to ground stud GND 12.

New Beetle:
– Remove the cap nut from stud GND 12 (near the fender).

See Figure 2.

– The ground terminals, cap nut and stud should be clean and free of paint or corrosion.
– Route the new ground wire along the existing
harness to ground stud GND 12.

Golf, Jetta, New Beetle:
– Fasten the new wire using the previously removed cap nut.
– Tightening torque: 9 Nm +/- 1 Nm
– Secure using tie straps as necessary.
– Reinstall the battery.
