Cars now all sorted. I pedalled (!!!!) to VW to get the bits thanks to the thread/guide on uk-mkiv's (pedal and 2 clips), ripped my lower trim off to save time as I can manage that, got a mobile mechanic out (local dub specialist, SDW automotive if you're in Staffordshire, awesome work!) who really impressed me by having it sorted in 20 mins, in the rain, AND fitting my trim back on and only charging me £20 quid.
So £45 quid including paying a pro labour, I'm happy. (sort of! lol)
What an utter crap design flaw though, I'll get my old pedal welded as a spare methinks!
