The drivers door top seal is making a noise when the window drops as you open the door.

It feels like rubber, i.e. a bit tacky, whereas the other door seals feel like they have a coating on so the glass drops smoothly with no noise.

I took it to BMW but they were no help.I have tried ptf spray and rubbed some spray silicon on, but no good.

I expect others will have had the same problem, any solutions other than replacement?
