Retailer Glass Reset Procedure for
Continental GT/GTC
BY634/5

INTERNAL

Introduction
In instances of multiple window drop concerns it has been found that to achieve the glass set specification, some
adjusters are being adjusted out of specification.
In some cases, since not all adjusters are visible, there is a possibility that the adjusters can be set to their maximum
inboard/outboard and induce excess tension in the regulators and affect the angle the windows enter the seals.
There is free play built into the front and rear regulators, therefore as the windows are being held in place by the cant
rail/convertible roof seals when closed, this may not be apparent when measuring. However, these extreme
adjustments can cause issues with how the windows enter the cant rail/convertible roof seals or how the front and rear
glasses interlock with each other, in some cases this can cause the seals to pinch and cause an anti-trap condition
leading to window reversal.
The following procedure should be applied to reset the regulator adjusters to factory delivered specification and then
fine tune any adjustments from there in line with the TPI specifications. To access all 8 adjusters the front door and
rear quarter panel trims will require removal.

INTERNAL

Front quarter glass adjuster reset - 1

The measurement between the bottom of the
mounting washer and division bar frame, is
12.5mm.
To reset this adjuster without removing the
quarter glass;
1. loosen the lock nut.
2. Screw the adjuster fully clockwise until it
bottoms out on the frame.
3. Unscrew the adjuster counterclockwise by
four complete turns.
4. Resecure the lock nut.
Figure 1. Image for reference, glass does not require removal
from vehicle

Finally, set the height and profile to the TPI
specification before proceeding to the next step.

Measuring from front div bar to rear of
the glass

Specification
971mm ± 1mm
If out of specification, refer to the next
slide to adjust the glass position
INTERNAL

Measure 100mm up from
the waist rail

Front door glass check and set

Loosen bolts -3- & -4- to ensure the glass sits in mounting position in its
lowest position. Then resecure the bolts.
NOTE: If the 971 mm ± 1mm specification shown on the previous slide is
incorrect, these bolts must be loosened to adjust the glass forward or
backward as needed to meet the correct specification.

Figure 3

GTC ONLY
If the specifications for interlock points 2, 3 or 4 cannot be achieved through normal
adjustment, insert the ratchet as shown in figure 4 and unwind both screws two full
turns counterclockwise.
Then loosen the two purple bolts (-3- & -4-) in figure 3, raise the glass evenly as
required, and re-secure the two purple bolts. Finally, return to the allen key (ratchet)
adjustment to set interlock points 2, 3 and 4 to specification. Check the 971mm
measurement has not altered, if so, re-adjust as required.

following points as shown in the following page
Before resetting adjusters remove the 3 13mm lock
nuts (1-3 in image) to allow adjusters to be fully
screwed in without damaging the regulator.
1 – Fully screw in clockwise until hard stop, then
unscrew 9.5 turns anticlockwise and refit the lock nut.

2 – Fully screw in clockwise until hard stop, then
unscrew 9.5 turns anticlockwise, refit the lock nut

NOTE: After you have carried out the reset
procedure, ensure measurements are rechecked as
per the check & measurements attachment

3 – Fully screw in clockwise until hard stop, then
unscrew 1 turn anticlockwise, refit the lock nut.

Door ECU wire check/replacement

For 25MY & Pre 25MY Only
After completing the regulator reset procedure,
replace the original motor-to-door ECU feed
wires (yellow in the photograph) with new wires
(part number: 000 979 242 E).
Approximately eight wires are required to achieve
the necessary extension length.
Parts should be sourced from VW/Audi.
Refer to the information below and ElsaPro
Repair Group 97 Wiring harness repairs
Figure 8

INTERNAL

Final checks
After all adjustments have been made and recorded. Door ECU basic settings must be
relearnt. Ensure battery is fully charged and passes battery test in ODIS.
Test window operation in all scenarios, e.g. global open/close, individual window
switches, driver door switches, convenience open/close (where applicable), short drop
functions when opening/closing doors and with convertible roof open/closed if working
on a New GTC.
Finally, ensure vehicle still passes water ingress test and does not have excessive wind
noise, any further adjustments must remain within ELSA specifications.
