HI,
Just taken delivery of a 2017 A3 2.0TDi S Tronic Quattro Sport Saloon 4dr (yes... for those out there - it has a boot)
It has the Cloth Sport Seats - but I've found a set of S Line Leathers for a SportBack which I'm very interested in.

I'm guessing the front seats will fit, but is the rear bench the same, or completely different?
I don't want to fork out 600quid and find the rears won't fit.

Also - will the wiring looms be there for the Electronic Lumbar Support and the Heating, or will I have to get these looms as well as the controllers and switches etc.

Thanks
