Odd TT Coupe Window Behavior

[ikisudama]

All,

Just bought a certified pre-owned '04 TT and have been experiencing a weird problem. On two hot days where the car has been in the sun for a period of time, both the driver and passenger windows have gone down on their own after starting the car, and in both instances, failed to completely roll back up all of the way. On the second instance (today), I actually pulled over to the side of the road, stopped the car and turned it off then restarted it, and the windows sealed properly.

I've searched the web and these forums and have seen a few suggestions, but haven't found a definitive answer, though I've come across a few posts regarding high heat situations and TT window electronics (such as this one: Audi TT: Windows & Doors - CarSpace Automotive Forums). I've done the 5 second down/5 second up reset function, but I'm not sure that is at the root of this problem.

Any guidance or insight would be appreciated.

Thanks,
iki

Have the window closure coded out from the central locking pump or disconnect the window closure wiring at the pump.

Appreciate the prompt reply! I will see if this corrects the problem.

Aside from re-coding/disconnecting to address the behavior, is there a potential fix for this that will allow the units to remain connected or is this a common diagnostic response to the problem?

Apologies for the inquisitiveness, but my experience with the car is limited (less than two weeks).

Regards,
iki

If both windows are droping i would look at the closure circuit and check for induced voltage or short to earth.If ok check all connections for pin movement.I would then be looking at the door lock micro switches for false signal for closure command or the pump for internal fault.Heres some code variants,i know it japan but the uk spec doesnt have the window closure valueSelf-diagnosis of central locking system

Window opens automatically
Release date: 04-Nov-2005

Problem description
1.In vehicles with remote control, the automatic opening function can be unintentionally activated at the remote control key. 2.Left/right electric window lifter opens unintentionally.

Cause
1.In vehicles with remote control, the automatic opening button can be unintentionally actuated at the remote control key (for example, when putting the key into the trouser pocket). Due to the relatively long range, two or all four door windows are opened. If no door is opened, the vehicle is locked automatically again after a waiting time of approx. one minute but the door windows remain open. 2.The opening function is activated by unintentional actuation of a window lifter switch on the driver's side arm rest (for example, with the ball of the hand when getting out of the vehicle). The relevant window is lowered until the driver's door is closed again (voltage maintenance terminated when door closed). Due to the arrangement of the window lifter switches, the passenger's side is mainly affected (front or rear). The opening procedure is not noticed by the driver getting out of the vehicle. The open window is first noticed when getting back into the vehicle.

Production solution
1.1. No change. 2.Factory coding of USA door logic (window lifter disconnected from voltage supply when driver door opened).

•Please inform the customer of the modified voltage maintenance. The basic coding for the central locking system has been increased by a value of "2048" in comparison with coding described in the Workshop Manual.
Service solution

In order to exclude an unintentional actuation, the automatic open/close function via remote control can be deactivated using tester V.A.G 1551 or V.A.G 5051, or the voltage maintenance can be deactivated by changing the coding of the central locking control unit (central module comfort system -46-) .

1.Deactivation of door window automatic open/close function via remote control according to "Body Self-diagnosis" Workshop Manual for the relevant type. Code for deactivation: "64". Procedure: Subtract the value "64" from the current code read out using the V.A.G tester and enter the new code number according to the Workshop Manual. This instruction is valid for the following models:

- Audi A2 (8Z)
- Audi A3 (8L)
- Audi A4 (B5)
- Audi A6 (C5)
- Audi A6 (C6)
- Audi A8 (4D)
- Audi TT (8N)

On the following models the function "Comfort opening via remote control" can be deactivated. The comfort locking via remote control remains active. Change the code via V.A.G 5052, central module comfort system -46-.
Audi A3 (8P)
Change the value of byte 4 from 6D to 69 via the option "Read/write long code".
Audi A4 (8E)
Change the code via the adjustment channel 62.
Audi A8 (4E) and Audi A6 (4F)
Switching the function comfort opening/locking on or off through the MMI menu "Car/window".
Or:
Change the code as desired, e.g. comfort opening through remote control switched off, but comfort locking remains operational, via adjustment channel 61.

Note:
The automatic open/close function via the door lock remains active, as described in the operating instructions - except Audi A8 (4E) and Audi A6 (4F).

2.Deactivation of voltage maintenance (USA door logic) - standard from 05/00 - according to "Body Self-diagnosis" Workshop Manual for the relevant type: Window lifter disconnected from voltage supply when driver's door opened. Code for USA door logic: "2048"

Procedure: Add the value "2048" to the current code read out using the V.A.G tester and enter the new code number according to the Workshop Manual.
Note: Please inform the customer of the modified voltage maintenance.
