WARNING
•
Attach a clear video and photographs of the failure mode to a new or existing DISS query (see examples in Figure 1)
Figure 1
•
Referring to the applicable wiring diagram - Conduct an electrical integrity check of the rear blind electrical circuit
•
Ensure a clear video and photographs showing the failure mode(s) are attached to the DISS query
•
Ensure a full ODIS log is also attached - Figure 2 shows an example of a DTC relating to the rear sunblind which could be evident within
address 0046
Hint: DTC B14F15 is not always evident within address 0046
Figure 2

NOTE: Figure 4 shows the rivet and star washer detached
Figure 4
NOTE: In this scenario (rear blind detached) the rear blind assembly must be replaced
Gearbox screws loose (Figure 5 and Figure 6)
NOTE: Figure 5 and Figure 6 show loose gearbox screws (not secured to 2.5Nm)
The following may also be evident which confirms the gearbox screws are loose:
Witness marks on the mounting surfaces
Or
Gap(s) between the motor and mounting plate
NOTE: Should the gearbox screws be loose the rear blind must be replaced - DO NOT attempt to secure the fixings

CAUTION
•
Reconnect the rear blind electrical connection
•
Attempt to operate the blind
•
If the motor shaft spins the issue is the rotator plate Jamming (Replace blind assembly)
•
If the motor shaft does not spin the issue is the gearbox jamming (Replace blind assembly)
Rear sunblind assembly - remove and refit process (Rear luggage boot cover removed)
• Apply masking tape to the parcel shelf sunblind aperture (Figure 9)

Installation is the reverse of removal procedure noting the following:
CAUTION
•
Prior to refitting the new sunblind into the rear section of the parcel shelf the operative should apply masking tape as shown in Figure 15
Figure 15
Hint: The end caps must be removed from the replacement blind assembly before fitting the new blind into the parcel shelf
CAUTION
•
Fit both end caps, the end cap screws should be 2+/- 0.5kgf-cm
Before refitting the rear sunblind the operative must check to confirm the software level within the Convenience system
central control unit (J393)
In the event the software version is V03.935.378.NW please conduct the software update instructions to completion
However
Should the software version be ZDC V03.935.428.LJ (Figure 16) the software is at the latest level the operative should refit the rear parcel
shelf as Rep.Gr 70
Hint: Before refitting the rear seats and side trim, the operative should open and close the rear blind (x5) cycles whilst monitoring the operation
of the blind - Should no issues be evident the operative should continue with refitting the remaining components
Figure 16
VERY IMPORTANT: The software update should only be conducted once. There is no requirement to repeat the software
update if the rear sunblind assembly is replaced in the future as the software should be at the correct level
Software update
The closed-circuit voltage of the vehicle must be at least 12.5 V during the update. Connect a suitable battery charger to
the vehicle. For further information refer to the Repair manual
During the update switch off all unnecessary consumers (ventilation, seat heater, interior illumination etc) ensure the main
light switch is set to ‘off’ and leave the driver’s door open
Because of the highest transmission stability you MUST use the diagnosis interface VAS 6154 (WiFi diagnostic tool) ONLY
in USB operation or the cable-connected VAS 5055 for the reprogramming (updating) of control units. If these units are not
available, the diagnosis interface VAS 5054 (A) can also be used in USB mode
Do Not under any circumstances use a Bluetooth connection to conduct the reprogramming (updating) of any control units
The operative must ensure the ODIS version is 2.32.0 or later
