I got mine from California. Cost me £40.00 if I remember right. A guy over there has loads of them, as they just scrap the flaps because of the weather. Seems to be tons of vw spares over there.
I have a T4 one bought by mistake... But it's busted although they are repairable . @Barry Haynes has done a couple of 1600 ones but dunno if he's repaired any later ones ?? Sent from my SM-G960F using Tapatalk
I repaired my T4 one. It's fiddly but doable if it is leaking from the ends. I'm not sure if a leak in the bellow part would hold.
I still have my old one, I asked Bazza if he'd fix it but he didn't feel confident doing someone else's. Understandable, it's a leap from tinkering with your own stuff.
