Hi, I have also been told 2 years or 19k service intervals. I have an A1 1.5 TFSI S-LINE manual, purchased March this year.
On my wife's A3 after about the 2 year mark a message pop up on the dash display saying service was due.
2 year service intervals seems the norm on some models. I previously have 3 mini coopers and they all had 2 year service intervals.
Came close to choosing the S Tronic how does it drive any issues. ( wish I had now )
My manual hesitates when pulling away in 1st gear, got dip the clutch or give more revs to stop it stalling, makes pulling out at junctions/roundabouts interesting.
