Convertib le roof - revised clip arra ngement - C fla p Bowden cab le (SC13/ 12)

Notes

Repair instructions

Technical background
A potential compression point has been identified between the tonneau cover hydraulic ram and the C
flap Bowden cable as it routes under the tonneau cover drive system (see Figure 1). A revised clip
arrangement has been specified to avoid this compression damage. In severe cases the damage to the
Bowden cable is such as to impair correct operation of the C flap, therefore a test of the C flap function is
required to ensure the Bowden cables are serviceable before implementing the revised clip arrangement

Figure 1
1.

Figure 1 details the original routing and single cable tie (C) securing the Bowden cable (shown in
yellow) . The detail at point A shows the potential contact point between the tonneau cover
hydraulic ram and the Bowden cable. The actual contact takes place when the tonneau is almost
closed and therefore the close proximity of the hydraulic ram and the Bowden cable cannot be seen
when viewed with the tonneau cover in a transient position. Detail B shows , in this case, a section
of the outer sheath of the Bowden cable that has been removed by repeated contact with the ram.

Note : as long as the system has passed the C flap function test then the absence of some of the
outer sheathe is not sufficient grounds to change the cables

Remedy
All affected vehicles require a C flap function check to ensure correct operation before either applying the
revised clip arrangement or in the case of failed function test refer to TPI 2033467 C flap Bowden cable
replacement

Customer notification
Customers do not need to be informed directly of this campaign. Please ensure that all affected vehicles
are checked and repaired during a service visit. You should also inform your new and used car sales
departments so that the vehicles affected can be checked and, if necessary, repaired immediately (and
not just before sales)

Check
If the vehicle is not already listed as repaired in the "Repair history" (in Elsa pro), check for the presence
of the correctly located cable tie (see Figure 7), should neither be evident carry out the required work in
accordance with these instructions

Genuine parts
The required replacement parts should be ordered from Bentley Motors Limited Crewe or through your
regional Bentley parts distribution centre

Work

Function test C flap operation and measure against specification
Systems performing to specification fit the revised clip arrangement to both Bowden cables
On systems not performing to specification refer to TPI 2033467 to carry out C flap Bowden cable
replacement
The following procedure describes the operation being carried out on the right hand side of the roof
assembly. The same operation must be carried out on the left hand side
The following should be noted before the procedures are carried out

(]]
Warning: There are no anti-trap features fitted to the linkage flaps, front header panel, tension bow or
tonneau cover. Ensure all persons are clear of the mechanism, and there are no obstructions in the
vicinity during the operation of the roof

Caution: To avoid a clash of panels it is important that the luggage compartment and tonneau cover
assembly are not opened at the same time. One of these must be fully closed at all times

(]]
Note: To carry out the following procedures, the power operated roof assembly will have to be positioned
partially open in a transient state. With the ignition on any transient roof position will only be maintained
for 10 minutes after which a warning will sound prior to the roof assembly gradually folding down as the
hydraulic pressure decays. Therefore consideration should be given to supporting the roof system during
the following procedure (see Figure 6)

()]
Caution: Whenever air tools are employed or compressed air is used to remove debris it is imperative that
the air is clean and dry and does not contain any lubricants. The exhaust from an air tool supplied with
lubricated air is likely to stain the hood
Function Test
1.

Throughout the test procedure correct system voltage must be maintained therefore ensure a
suitable battery charger is connected to the vehicle via engine bay charging lead WT 10165

2.

With an assistant operating the power operated hood observe a full open and close cycle . During
the cycle note the operation of both C flaps .

3.

Both C flaps should operate simultaneously and in synchronisation with a smooth action

Referencing figures 3, 4 and 5 take a measurement between point (A) , C flap obscuration lip, and
(B), tonneau brightware securing bolt head. The correct specification for th is measu rement is
74mm to 90mm. If this measurement is not to specification or the C flaps are out of synchronisation
or judder during operation then refer to TPI 2033467 to carry out C flap Bowden cable replacement.
If the C flap is to specification then perform the revised clip arrangement

With the tonneau cover still held in the vertical position, support the tension bow with a suitable prop
taking care not to damage any trim (see figure 6)

7. Remove the original cable tie securing the Bowden cable (C) to the tonneau cover drive system (see
Figure 1)

Figure 7
8.

Referencing figure 7 secure the Bowden cable to the tonneau cover drive system using two cable
ties. Ensure the Bowden cable is retained underneath , along the bottom of the bracket, where it
cannot come into contact with the hydraulic ram. It may be necessary to temporarily release the
Bowden cable from other retaining clips to gain sufficient length to enable the two new cable ties to
be attached .

Identification
The presence of cable ties conforming to the location specified in this document will serve to indicate that
