The bit I didn't mention about the design....that tape, it wasn't on the original door - certainly wasn't on my 2007 model. Only on the replacement rear cupboard door that I bought were there a couple of pieces of tape poorly adhered to the inside, 20 pence worth perhaps at hight street price.
It is a "bodge fix" for a flawed design, a bit like putting a bit of string behind a low quality zip so when the zip fails, at least its not a catastrophic "wardrobe malfunction"....does anyone imagine that VW's design intent was to have a tambour door with a couple of bits of gaffer tape to provide structural integrity in a £60k vehicle?
Nope, but its a lot cheaper to slap a bit of gaffer tape on there as it goes down the production line than to re-tool the multi-thousand dollar twin shot injection moulding tool for the thermoplastic elastomer part of that assembly that is too weak.
A better physical, although aesthetically flawed, fix with their gaffer tape, would be to put it on the outside of the bend where it would actually do some work in normal use. As it is, on the inside of radius, it ends up normally in compression rather than tension and as anyone who has tried pushing rather than pulling on a piece of gaffer tape knows, that's not what its best at!
It is a "belt and braces" solution, when the elastomer rips, it limits the size of the gap that opens up, (provided it sticks of course, which it didn't on the replacement I purchased), so hopefully the owner doesn't notice or complain, a bit like the diesel emissions, and VW stay profitable, albeit with limited ability for their ex CEOs to travel freely in the US ;-)
