Sticky windows

[mattchuu]

I have a Mk5 golf and a couple of the windows are starting to get very slow when going up and down, and i think it's time to lubricate the channels - one of them has a 50% chance of the auto-close failing even after adaptation.

I've done some research and it seems the correct product to use is a PTFE paste that my local dealers don't have and one of them suggested lithium grease, which i think is a bad idea.

I'm guessing since the genuine product is PTFE it's free of silicone as well, so it' a dry product that won't attract dust and lithium grease is anything but dry.

Bunnings has a WD-40 brand ptfe spray product that looks good, is there anything else suggested?

Is gummi-pfledge usable as a lubricant? i thought it just softened rubbers?

Thanks!

The rear doors had a software update for the auto-close.

I've used silicone on the bailey channels in the past with no issues. I don't believe it's viscous enough to catch grit.

Ah, thanks for the help, i used silicone and they are moving quite a bit faster now!

Should i ask VW to check that the auto close update has been applied when i get it serviced next? is there a special name for the update that you know of?

Thanks!

I remember seeing it in a tech bulletin about 6 years ago.

Easiest way from your end, would be to tell them what it's doing and hopefully they'll get it sorted without too much trouble.
