Hi,
New to your forum, I have introduced myself on the new members page where I have listed the pas problems encountered in the last 9 years with my TD4. I also have been suffering from boot door window problems for a few years now, probably since the window got frozen up in Germany. The door always opens, no problem. Same with the dashboard window opening mechanism, perfect. However, when I open the boot door the window glass doesn't drop as much as it should. If I push it down it will often close correctly, sliding up into the slot under the trim. But not always. The door catch also sometimes doesn't engage properly, leaving me to spend 5 minutes or so manipulating the catch with the edge of the key and opening it again electronically until all functions correctly. I intend to take the car to my friendly local Citroën garage, a lot cheaper than the local Land Rover dealer, but as he doesn't know the ins and outs of this sort of problem I am hoping my symptoms sound like those others have experienced and cured! If I can point him in the right direction, he can deal with it. Could it be the Window lift ECU mentioned on another thread? I should be grateful for your experience. Thanks in advance!
