Took delivery of my Q3 40tfsi Quattro automatic having selected every single option available.  But despite being a total replacement for my previous Q3, it could not handle snow and therefore the two hills to my house …… all down to tyres.  The car came with Goodyear F1 asymmetrical series 3, so after 600 miles tyres fully replaced by Audi to Michelin cross climate series 2 and the difference was incredible and the car performs exactly as it should.

You're lucky you got them to do that!

I complained and just keep going and they offered the new tyres as replacement

Taken off someone else’s pre purchase vehicle?? 

They gave me back my initial Goodyear tyres, plus the all season tyres they fitted still had the stickers on them, so they were brand new
