^^^ Spoken like a true scots man

Here the break down of parts (was previously missing the lower grill trim thats black on the ED35 and pearl grey on the normal GTI): -
Lower Spoiier = 5K0 807 110 B 041 @ £73.14
Bumper Cover = 5K0 807 217 CK GRU @ £324.11
Closing Element Left = 5K0 807 611 = £27.58
Closing Element Right = 5K0 807 612 = £27.58
Lower Grill Trim Black = 5K0 853 611 G 041 = £106.15
My prices haven't been updated for a while so might be a bit off.
So as Kenny said not cheap 
Just checking - is the grill not 5K0 853 655 G 041?
Also seems to be another spoiler part, 5K0 805 903 G 9B9, maybe that is the bit that links the spoiler to the bumper?
I am pretty sure 5K0 853 655 G is the gloss black u trim that goes around the lower mess grille.
5K0 805 903 G seems to be the valance that clips into the bottom of the bumper cover. If you search for the other variations of that part number (without the G) that is what shows up.
Still haven't really figured out how the lip spoiler clips into the car. I asked on a German forum and this is what I got. Google translate makes it somewhat hard to understand...
