Figure 3
Run the test plan, selecting IDE01834 and IDE01839 as the measurements (Figure 4) and ensure the 12 Volt battery is functioning correctly
(Figure 5)

Figure 4

Figure 5
NOTICE
Should any issues be evident with the 12 volt battery / system this should be rectified first before proceeding any further

The window closing time results (as below) must be attached to a new or existing DISS query
VERY IMPORTANT: Do not proceed with the time measurement request instructions unless the battery is confirmed to be
within specification (battery test) a 12 volt battery charger must also be attached as per Rep.Gr 27
2) Passenger side front and rear window closing time

Section 1 – Software update to the rear door control modules 00BB and 00BC – Short drop function elimination
NOTICE
IF THE ED18 CAMPAIGN HAS ALREADY BEEN COMPLETED ON THE VEHICLE PROCEED TO SECTION 2.
3) If the ED18 campaign has not been completed on the vehicle, perform the software update as described below and ENSURE ALL STEPS
ARE COMPLETED FULLY.

The following software update eliminates the rear window short drop function
•

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

3a) Referring to Figure 6 - Within the Special functions tab - Select SVM - Code Input (Point A)
• Select Perform test (Point B)

Figure 6
3b) Referring to Figure 7 - Enter the SVM code 372WDD01

Figure 7
3c) The control modules will automatically be updated one by one, starting with 00BB (driver rear) and then 00BC (passenger rear)

Upon successful completion you will get a failure message of 8113 SVM Error.
NOTICE
If you get any other error code, such as 8118, please raise a full technical DISS query with the log submitted online.
3d) On completion, open the doors and ensure that the rear windows no longer drop. Then complete the steps below:
•

Switch off the ignition

•

Remove the diagnostic interface from the OBD port

•

Switch off and remove the battery charger from the vehicle

•

Close the bonnet, boot and all doors

•

Damage

•

Splits

•

Tears

•

Misalignment

•

Incorrectly fitted / located

•

Drop glass seal deformation (see Figures 8 and 9 as examples)

Figure 8

Figure 9
NOTE: Any issues found with the window seals must be rectified before conducting the remaining steps
5) VERY IMPORTANT: Referring to the attached PDF instruction the operative must now conduct all steps to completion
before continuing to step 6 - The process within the attached PDF instruction MUST be performed to completion in all cases
regardless if the window measurements are initially within specification
NOTICE
Please ensure all steps are followed within the attached glass check / measurement PDF documents, the operative should
be aware there is (x1) document for New Continental GT and (x1) document for New Continental GTC please ensure the
correct document is used depending on vehicle type

Ensure all required measurements are attached to a new or existing DISS query
NOTICE
If not already done so, review eAcademy Digital Learning HUB videos on Glass Setting Procedures for GT / GTC before
proceeding to ensure accurate and repeatable measurements are being made

The process is the same as demonstrated in the videos, however, for 25MY vehicles, one of the measurement points has
changed.
PLEASE FOLLOW THE ATTACHED GLASS SET MEASUREMENT TABLES CAREFULLY.
Log into eAcademy - Select / open Digital Learning HUB - All content - Technical information - Continental GT & GT Convertible (2017+)
Technical Information

CAUTION
When conducting step 7 extra care must be taken to ensure the interior trim is suitably protected, any water which enters
the vehicle due to a leak must be dried / cleaned immediately
Hint: Ensure all windows, sunroof and convertible roof (where applicable) are fully closed before conducting the water leak check
7) Conduct a water leak check to ensure that water is not leaking into the vehicles interior
•

Water leaks must be resolved before returning the vehicle to the customer

8) Conduct a short road test to check for any wind noise related issues
CAUTION

•

Completed final glass measurements (Post reset / readjust)

•

Confirmation of glass / window closing times (as step 2)

•

Confirmation of the 12 volt battery condition

•

Images of any issues found with seals

Should the issue still be evident after conducting steps 1 through to 16 the operative must raise a new DISS query or
