2001 330i electric window breaking

[bach]

My front passenger side window all of a sudden started making a weird noise as it goes up and down. It seems like it is getting off track as it goes up and down because I can see the window tilting. Anybody have this issue and how do I fix it (car is out of warranty)?

Thansk :screwy:

I have got 330ci 2000 and my front windows started to make a horible notching/clunking noise when they went up (Gradually got worse over time). BMW said that it would need to two new regulators but on closer inspection turned out to be a loose bolt holding the mech in place. I didn't do the work so am not sure which bolt but maybe worth a look all the same. Hope you sort it easily enough
