Convertible roof - C flap Bowden cable replacement

Customer statement I workshop findings
Check convertible roof function

Technical background
Continual improvement in system designs can produce developments that may benefit older vehicles.
One such development has been identified in the convertible roof mechanism. Re-route the C flap
Bowden cable using a longer cable reduces the friction build up in the system and thus promotes smooth
operation of the C flap and longevity in the system

Production change
The longer cables and cross over routing have been integrated into later hood designs from 2013

Figure 1
Figure 1 depicts the original routing of the Bowden cables. Note the sharp radius of the Bowden cable
and the multiple clips securing the cable to the tonneau cover all these contribute to the increased friction
in the system . The new arrangement removes the sharp radius and deletes all but one of the clips
securing each cable to the tonneau cover

Figure 2
Figure 2 depicts the new longer cables following the cross over routing

Measure
If a specific C flap function issue is being worked and that issue necessitates replacing the Bowden cable

then it would be advisable to make the owner aware that you are able to fit the later cross over Bowden
cables. If the initial decision to replace the cable was a result of Campaign SC 13/12 then the fitting of this
new cross over Bowden cable will be warranty, otherwise this service enhancement to improve durability
does not qualify for warranty
1.

Remove the C flap Bowden cables, reference Rep. Gr 61 C flap Bowden cable - To remove and fit
In addition to the above workshop manual procedure fully remove the tonneau carpet panel, this
requires a modification to accommodate the new Bowden cables
Fully remove and discard the hood stowage compartment carpet panel, this panel is replaced

1.

Produce two 30 mm holes in the tonneau carpet panel. Position each hole at 230mm along a line
drawn 5mm out and at 90° to the vertical C flap cut out on the panel (see Figure 3, 4 and 5) Note in
Figure 3 and 4 above the hole position has been highlighted by a white chalk circle

2.

To fit the new longer re-routed cross over Bowden cable take into account the following operations

The pin securing the drive end of the Bowden cable can, for ease of assembly, be inserted in either
direction (see Figure 5)

Ensure the new Bowden cable, arrowed, passes under cable cluster D (see Figure 6)

Figure 7

Loosely position the modified tonneau carpet panel feeding the right Bowden cable through the hole
produced in the left hand side of the carpet and left hand Bowden cable through the right hand hole
(see Figure 7)

Figure 8
6. When connecting the new Bowden cable to the C flap the hood will need to be lowered to produce
sufficient length in the Bowden cable to enable its attachment to the C flap (see Figure 8)

Figure 9
7.

Start clipping the cables at the two new positions under the tonneau cover hydraulic ram as per TPI
2033508. Ensure the cable ties are placed at the points identified by the ring of black tape (see
Figure 9)

For each of the two new Bowden cables three SPC 1442 and one 300971838N cable tie are used
in the locations shown in figure 10 and one original clip shown in figure 11 , all other clips that were
previously used to retain the Bowden cable must not be used and therefore can be removed and
discarded (see Figure 9, 10 and 11)

Figure 12

The new Bowden cable has the clipping points identified with a ring of black tape, ensure these
markers are aligned with each clip. When clipping the Bowden cable do not over tighten the cable
ties , figure 12 shows an Allen key used to gauge the cable tie pull down ensuring a running
clearance is produced and over tightening does not occur

10. Disconnect the high mounted stop lamp cable at the body plug to enable it to be routed through the
modified tonneau cover panel. Tape the high mounted stop lamp cable to the new Bowden cable at
points (A) figure 13 then fit the longer cable obscuration sleeve (part number 3W7937115B) to the
high mounted stop lamp supply cables before reconnecting the body plug (see Figure 14)
11. Note: If the obscuration sleeve , part number 3W7937115B is not available the original sleeve fitted
to the vehicle can be used with the addition of a section of black tape

Figure 15
12. Follow the remaining refit procedure as contained in the workshop manual, taping down the high
mounted stop lamp cable (B figure 15) to the painted body before fitting the new stowage
compartment lower carpet (part number 3W7863479F) in the process (see Figure 16). Reference
