W211 07 Window Issue

W211 220CDi Saloon 07 Plate

Hi

I'm having a problem with the n/s/f window... It was smashed in a few months ago and then replaced by Autoglass. Since then the window has never been able to close with the Auto-Up function. It will get to the top then bounce back down again.

I have tried resetting it on Star. And by resetting the memory as required by holding in the up position and then in the down position etc but to no avail...

On closer inspection it seems that the glass seems to "wobble" so doesnt sit straight in the runners/guides so when you click down the glass move a little in a diagnoal direction (maybe a cm) befor continuing its rather slow and sticky ride down. When you then try to close the glass will almost correct itself and move in an opposite diagnoal direction and then make a laboured move upwards.

I tried investigating by removing door card. I was thinking that the glass was loose (If you hold the glass when window is half open you can wobble it up and down on the front (of the door) side.

Looking at the clamps that hold the glass, they were nice and tight but the runner that the clamp was on was allowing the whole clamp to move slightly hence the play.

Does this mean that I have to replace the whole regulator or is there any other adjustment possible to hold it nice and tight?

Thanks in advance for your thoughts!
