Had another bugger of a time getting the Golf's frozen tailgate open this morning despite going out last night and making sure the seal was dry. Eventually got it open using one of Mrs Motties boot pulls - I hooked it under the bottom lip of the tailgate and gave it a good pull. When I tried to shut it, it wouldn’t latch and I thought I’d buggered the latch but looking closer, it appears it's been the latch that’s been freezing so I’ve been outside fiddling about until I couldn’t feel my fingers anymore, stripping off the hatch panel, freeing off with WD40 and then squirting oil everywhere. I’ll find out tomorrow morning if I’ve been successful.
