Technical product information
Convertible roof - C flap Bowden cable replacement

Transaction No.: 2033467/2

Customer statement / 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 SC13/12 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

Figure 3

Figure 4

Figure 4
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 in addition to the workshop manual
procedure Rep. Gr 61 C flap Bowden cable – To remove and fit

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

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

Figure 7
5. 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)

Figure 10

Figure 11
8. For each of the two new Bowden cables three SPC 1442 and one 3D0971838N 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
9. 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

Figure 13

Figure 14
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 3W7863479G) in the process (see Figure 16). Reference
