The problem sourcing from the likes of ebay is that the part number seems to be taken from the ignitor or ballast. I'm not sure where it is on the headlamp itself. You need one which is Bi-Xenon and has cornering
It is a pain in the back side, I know but just checked out a online store that sell the original headlight for 600-something! There are others as well much cheaper, but still in 200-300 pound range. From your links above one is cheap looking aftermarket part and the other one is damaged second hand unit. God only know how they expect this to sell for £150. Most other second hand are either already broken or missing information about it's type.
