CraigCan't see the link, but the price is about right for a dealer. If you look on Ebay there are a lot that are claimed to be genuine, but I have doubts, £25 seems to be the price that the Ebay ones command.
Suppose at the price they are worth a gamble. if they turn out not to work you can claim a refund back through Ebay? What Model & year car you using it in?
I have a spare genuine VW lightning connector that I purchased for my polo and then Golf came with one if you are interested.
