Help Please S4 / s-line rear diffuser


Registered User
Getting a quad exhaust fitted on Friday to my avant (1.8T has a double on the left side as stock) so bought an S4 diffuser, didn’t realise I needed a piece of trim for the diffuser too. Looks like another £150 for the chrome strip


Anyone have an S-line or S4 quad outlet diffuser going, or have an idea on one that isn’t £300?

Also if you know whether I can fit the mesh insert (no. 19) in the place of the chrome strip (no. 18) or how the diagram works, I’m pretty confused!


Thanks all, bring on the burbles.

Rear splitter is also different between the B8 and B8.5. I have an S4 B8.5 and it doesn't have the chrome insert
