Just picked up my diffuser
As above, the pre-facelift S3 diffuser is one piece. It comes in a platinum grey finish. The top section needs to be sprayed to match your car, the actual diffuser section can either be left platinum or sprayed a colour of your choice
This is the part number I used to order - 8P3 807 434 G 1RR
It was £100 inc. VAT from TPS
Just to be clear, this is the diffuser in questHi I'm looking for help ion;


Hi guys, sorry to bump this but I really need answers
I was led to believe on this forum that the valence and diffuser are two separate pieces that need to be bought separately
However, a local parts supplier is adamant that they are one piece and did not become two pieces until the 8P3 honeycomb type diffuser. I showed him the picture of the car posted above and he is positive that the valence/diffuser are one piece
I called Audi to try and get confirmation and they were less than useless. They said that there are 4 or 5 different diffusers that it could be but they think that they know which one I wanted, but they couldn't be totally sure. To be sure though, they had to order it in.... and get this, if it isn't the right diffuser I still need to buy it, because they don't accept refunds on this type of order. What a joke.
I asked if I could at least have the part number of the diffuser in question so that I could cross reference with you guys on here to be sure it was the correct one before ordering, but they refuse to give out part numbers - apparently they're sick of people phoning up for part numbers then going somewhere else to buy the parts. Again, what a joke.
So please guys, if anybody knows the part number I would really appreciate if you could post it for me! 
Hi need help with it please. Can I fit a s3 facelift 2009 rear diffuser on a 2007 rear sline bunber?
