That does sound frustrating. I have come to the conclusion that I love my van, but the sad thing is that Volkswagen obviously doesn’t. They’ve taken a great idea with a decades long loyalty of owners, and manufactured it to the lowest commmon denominator they can get away with. When I was in my teens and taking apart VW motors, the simplicity and quality showed pride in manufacturing that made owners wink and wave at each other. I believe the same will continue to happen with these vans, but no thanks to VW. The idea is so good that quality 3rd party manufactures will supply replacement parts with a pride in design and manufacture that these days VW can’t be bothered with. For the Nth time the trim has popped off the sliding window on this 6 week trip to the Alps. I don’t bother putting it back on. The first time it happened I took a look at the solution some VW engineer had designed to hold it on, and felt sorry for him. He probably knows already that someone with higher standards than him will make a replacement part for people like me who will keep using our vans for years.
