Avant Lower Valance - Part No??

That's not from a b6, the b6 is the complete lower valance, not just the diffuser.

Pretty sure part numbers are 8e0 for a saloon and 8e5 for an avant?

Confirm that is probably a B7 - part definitely not for a B6.

For B6 Saloon....
Rear Upper Bumper Cover: 8E5 807 301 AE GRU
Rear Lower Bumper Cover: 8E5 807 521 G GRU

For B6 Avant replace 8E5 with 8E9.

For the lower "valance" guess at around £150'ish from Audi and includes the black sticker "decal" - call your dealer and ask!
 
My rear bumper is like this and I was under the impression that you could just change the bit highlighted in red - hopefully the part number from Sam ( 8E9 807 521 A ) is correct.

Correct - I did that on my Saloon from having the boring grey twin outlet valance and changing to the S-line type.
Twin outlet Avant will be as follows: 8E9 807 521 G GRU
It's all in the letters as to what style you get.

My saloon S-line valance from Audi invoice was £143.49 (June 2009) and my part number was 8E5 807 521 G GRU.
