Heating question

[Borys]

I'm on holiday at the moment. Got a rented 2015 audi a3 1.6tdi.....well shocking when I started it first time, literally heating started to work instantly !!!! Was a bit upset as compering to my s8 that was supersonic. S8 takes good few minutes. Going around settings in a3 it has electronic heater!!!!! Damn wish my S8 had that!!!
Which brings a question, any way to get heating to start working faster in a d3? I heard something about heater coming on while still me sitting at home??
