I think it's more like every owner of a VW of "a certain age" wants a
spare fuel pump relay to leave in the glovebox. Generally they can be
disassembled and made to work again, but it's not something you want to
do at the side of the road when it's raining and your car just shat the
bed. So if you do go that route, I'd get two.
