I just bought a 2010 XF and I noticed when I roll the window completely down and then roll completely back up it will reach the top and then automatically go back down again. I've had to inch it up to get it to stay at the top. Is this a setting or just something broken?

 

Make sure the seals the window rides in are clean and try lubing them with a dry silicone. Then reset the limits of the windows by holding each switch fully up for 5 seconds then drop windows and hold switch down. This resets the electrical resistance reading learned by the door modules. If neither of these works the motor is pulling too many amps and i would replace the regulator and motor assembly

 

Thanks. Looks like the reset worked for me
