Audi tt caliper hangers and a8 rotors need help

I'm new to the forums but have had plenty of petrol vw's.
Went to do the brake upgrade and the audi tt brake hangers
Dont even come close to the mounting holes. This is on a 2005
Passat tdi. Bought whole assemblies from napa thru work. Are there different audi tt calipers???Even cross referenced the bracket 8n0615125 which is now 1j0615125a.any help would be great thanks

I've done the TT caliper bracket upgrade on my car, and it only needs those brackets, and rotors from and Audi A6. Stock calipers and pads stay and mount to the TT brackets.
