Just fitted these, now £30 for a pair of non heated ones from local VW dealer.
Fitted easily enough, on first drive found them too low like most others. Have used Torx 10 anti-clockwise 4.5 turns until I felt some resistance, tried and it was a bit too high in the driveway, some going onto roof. So turned it back 1 turn clockwise, still a bit high but I’ll leave it to see what it’s like when driving.
I found it fiddly to adjust in place, so I unclip them from the bonnet to adjust, without disconnecting from the pipe though.
