The ones from bold sport and various ones on eBay are definitely 'copies' despite any connection VW AG may have with FAW...
The bold sport ones differ in many ways, look at the quality of the rear plug housings, the fact you have to twist your OEM wiring loom through 180' to fit it correctly as they installed the plugs back to front, they are also missing the felt sound deadening strip at the top of the unit where the facia clips rests, no correct VW part numbers or the VW AG holographic 'genuine' parts ID sticker..
Just like the Bold sport mk6 headlight switches that have chrome accents rather than brushed and have the sidelight emblem twisted through 20', cheap replica items..
I'd like to add I have no problem with such items as they generally seem to work ok, but I do have a problem when they are represented as 'Genuine OE VW' parts when they clearly are not
There's plenty of OE climate units on eBay.de and the last one I saw went for £80
