Going to view the above car this week and having owned a few A4's, am new to the A5 models. Any known issues to look for? Its the 3 litre diesel model

Also, what is the S Tronic gearbox like please, as when I bought my 3.0 A4 cab years ago there was a known issue with the auto boxes and made me buy the manual. Any tips or pointers greatly appreciated

Thanks all
