A3 sportback. Sports suspension deletion ?

[Redders2]

Bought a used A3 Sport back from Blackburn Audi yesterday (63 plate) and was wondering if there's a way of finding out if my car has had the sports suspension deleted? It doesn't seem as firm as I thought it would. Did have an A4 black edition directly before this so that could be throwing me off a bit. A year or so ago I was driving a mk6 golf GT with the same suspension (15mm lower) as the A3 ought to have, but I'm sure the gt felt firmer. Any help would be great, thanks.

In the service book and also in the spare wheel well is a sticker with all the build codes for the car.
You can input these into a decoder on the www.
Most people seem to use igorweb.

Could be down to wheels and tyres. Big difference on my car between winter 18s and summer 19s. Feels much firmer on the 19s with Michelin tyres.
