Window Drop Issue (advice appreciated)

[ChrisA4Cabby]

Hey all,

Just bought this vehicle, mint condition but a few minor niggles to solve.

To save me disassembling the drivers door, would anyond happen to know if it uses a door angle sensor etc so that it knows when to drop the window slightly to not hit the roof when closing or does it use the door limiter bar? (Actually just re-read this part and probably has neither if the window is already dropped when door first opened).

Short version, when in the vehicle, put window all the way up, pull door handle and the window drops a couple of mm as expected, swing door open, no problem, start closing door and when its nearly 6inches from totally closing(door) the window drops perhaps an inch, soon as the door totally closes it *may* send the window up a few mm as expected to seal BUT not compensating for the inch it overshot by and therefore doesn't seal, have to climb in through the pass side and use the window switch to totally close it.
If I slam it quickly it doesn't seem to have the chance (as in fast approach but not actually slamming it).


Does have a habit of forgetting auto close position(drivers door only) so am guessing this could be a wiring issue with the flex (door to A pillar).

Thanks


p.s posted this exact question a few days ago on a different site, seems this one has a lot more replies.

Does the DIS show the driver door open/closed correctly.

Hi, thanks for the reply,
It does yes, the interior light works correctly etc, just seems there is a *position* on approach (when closing) which causes the window drop, if I open the door slightly beyond it and start closing it again, it drops a further inch, am thinking this will likely be the wiring loom for the door, had a feel around the flex cable and moved it around to see if the position changes or get it to drop but no difference.

Righty,
After disassembling the door and seeing how it works, no position sensor etc as it's based on the locking mechanism for knowing when the door is closed/open, didn't help as no service/repair manual etc and also my first Audi (BMW X5 Sport defector which may be getting sold cheap when I even have the time to do anything with it).

By seeing inside the door this then it was easy to diagnose.
Door flex cable removed, thick red wire cracked insulation showing slight strand damage, thick brown wire almost totally broken, came apart in my hand, cables repaired and job done, hope this may save someone some headache with this issue.
