Okay, having seen that black car it does look as though there is a large square hole on some cars. Looks a bit strange. Anyone know why the smaller holes are present in the UK spec? What do they actually achieve?
Large rectangular 'hole' is for DSG cars - cooling to the gearbox.
Seems to be that on some markets, i.e. Australia got DSG cars with these cut-outs (according to posts on VWVortex.com forum). But in Sweden at least, we don't get the cut-out on DSG's. Saw that on some pre-production cars tested by the press. Upon asking my dealer about it, he just stated that they were pre-production cars. Strange if the Australians would get pre-production cars  So I guess there might be a reason for these, related to cooling of the gearbox, on some markets. makes one wonder what will happen on a track day [?] Maybe one shall try to get Australian spare parts...
The gaps/holes in the bumpers are cooling duct to the brakes to assist
in less fade...more air to the brakes the less heat generates under
braking. Cooling the bay in general like that is obviously good
as well, just helps things tick over smoothly.
It was probably in response to some testing that VW did and realised it
would significantly aid the car...at least thats what I think.
Larger ducts were available on the MKIII models to aid with braking and
getting colder air into the bay. The colder and denser the air
thats drawn into the bay the bigger the bang and is probs a good idea
with a turbo'd car.
Presume we all know this...hope i'm not patronising or owt...just no one has mentioned it as yet.
