Dammit, nowt's ever simple is it, 36 pages of discussion about it all in German!
I did a degree in it 12 years ago, and still can't work out whether its an easy job or not, or whether it'd work, or just break the boot!
When I press the boot opening key fob switch, it still seems to me that you have to manually click the boot open with the VW badge, so with that in mind I don't get how any springs could open it, but that said, am no modding genius.
I'll just stick to research for now, until someone of authority can help me, no rush, only had it a week!
