Hello all!!!

I purchased a 2017 XF S late Feb and, whilst I absolutely love it, the passenger side front window has developed a whistle when getting above about 50/55mph. Upon inspection, I can push the window up at the front end of it by about 3mm after it's been closed. I've tried resetting the window using the window down & hold til click and wind up & hold til click, but it hasn't solved the issue. 

Has anyone else experienced this issue, is it common and has anyone any idea how to fix it, please?? 

I've checked the door seals and noticed they're not well stuck, but all seems in place as should be, but this whistling is driving me mad!!

Your help, experience and expertise will be hugely appreciated!!

Hi Andy

The window regulator stop function works on monitoring the current drawn when closing the window. When current drawn increases (end of travel or resistance to closing -such as a trapped finger) it stops. In your case it sounds like either there is resistance at the top of travel - maybe loose trim at the top of the frame or (more likely) the front of the window has dropped out of alignment. I assume from your post it is not possible to raise the rear of the window by the same 3mm as you can the front? If so, my guess is the front support mounts have dropped.

Have you tried re-setting whilst "helping" the front to close that extra 3mm?

The previous model details are here but I would imagine the windows are not dissimilar.

Thanks Big John!! 

Your assumption is correct, the back end of the window goes all the way up.. I shall give this a try tonight. 

Thanks again!!
