Ebay, maybe tut tut, as mostly at least genuine VW Group parts get auctioned off due to age or time kept in stock - or, because they have been improved and so superseded. Getting auctioned off due to packaging changes does not bother me and I'll admit buying same item, like NGK sparkplugs very cheaply when VW Group last changed their packaging, but for most other things, if VW Group have had a reason to revise a part, which mainly but not only, due to failures, I'd rather go for the latest better version, though in this case maybe not a big issue though improving weatherproofing of this item might have forced a version and so part number change.
Just my current thoughts - not much more!!
