Idle adjust Screw Washer

I've got a problem with the tickover on my Mk 1983 Gti.   I've read through the archives and it seems that my idle screw has probably worked it's way loose.  However, lots of people recommend replacing the washer o-ring.  Can anyone please tell me where I can get one or what the part number is from either GSF or EuroCarParts.  Or even if anyone has a new one kicking around!!  What should they cost new?
Many thanks

VW Dealer is the obvious place, it costs about ?3 and that includes the whole thing. I don't know the size of the washer itself, but I wouldn't fancy trying to fit it over the screw.

a small amount of silicon sealant or plumbers tape is a temp fix, did it on mine as mine needs replacing :wink:

I used the Plumbers tape solution, works a treat
