Technical Background
The wiring of the fuel tank
senders can rub through on
the service opening for the
fuel tank.
If one or more of the above
DTCs are stored, open the
service cover under the rear
seat bench. Inspect the fuel
tank wiring harness near the
body flange (Figure 1). If the
insulation is damaged, repair
using the steps below.
If no damage is found,
continue with standard
diagnosis.
Figure 1. Location to inspect for rub through.
Production Solution
Improved harness routing and addition of abrasion resistant tape in production.

Service
1.
Remove the trim of the fuel pump control unit from the underbody of the vehicle.
2.
Disconnect all connectors from the tank wiring harness.
3.
Loosen the harness clip from the
retaining strap of the tank so that
the wiring harness can be pulled
upwards through the service
opening (Figure 2).
Figure 2. The arrow points towards the harness clip to be removed.
4.
Remove the rear seat bench.
5.
Open the service cover and disconnect the connectors for the fuel pump and the tank senders.
6.
Carefully pull the wiring harness upwards out of the service opening. After sufficient clearance is gained,
repair the damaged wiring harness with crimp connector 000 979 940. Ensure a watertight repair to the
harness is made.
Tip: The harness clip (Figure 2) has to be removed from the tank to gain enough clearance for the
repair. This harness clip does not need to be replaced for the repair however it will need to be refit after the
repairs are made.
7.
Wrap 20 cm of textile adhesive tape (D 004350A2) around the wiring harness in the area of the body
flange.

8.
Attach self-adhesive foam pad
(443201365B, 100x100x6mm). Cut
the pad into two equal sections
measuring 50x100mm. Attach one
section to the underside of the
body flange (Figure 3, A).
Figure 3, A and 3, B. Section A and B are attached to the topside of
the tank and the bottom side of the body to prevent further rubbing of
the harness.
9.
Attach the other half to the top side of the fuel tank so that the wiring harness will not rub through on any
components (Figure 3, B).
10.
Refit the wiring harness and plug in the connections for the fuel pump and tank sensor.
11.
Reconnect the cables to the fuel pump control module.
12.
Secure the wiring harness to the welding stud of the tank strap with the harness clip. Ensure that the wiring
harness is at least 1cm away from the tank strap.
13.
Reassemble the vehicle, however, before closing the service cover check the wiring harness again for
correct routing.
