Rehau bumpers

Sorry about that no obligation start
Anyway I needed a bumper for my car a 2011 a3 and when I went to collect it I was looking for the part no everywhere and it didn't have one it only had a rehau sticker on it has anyone heared of them is it some sort of copy part?
 
Rehau are a plastics company, they do double glazed windows so its plausible they could be into plastic car parts as well
 
I'm after a replacement bumper for my a3 2011 and just saw this s line for sale on eBay but turned out to be rehau am being cautious
