Out of interest why do you turn it off?
Personally, I always leave my car idle after a drive to give the turbo chance to cool. Some say the cars don't need it these days, they may not but it will only do good for the car even if it doesn't need it.
I HATE the fact that I could drive for 4 hours straight in whatever manner, pull up at a set of traffic lights and the car instantly shuts off. It's the startup procedure for me, start engine, start stop off and then pull away.
I never drive the car very hard close to home, always back off a few minutes before to allow the oil to cool and circulate the turbo. For a typical journey, I will leave the engine running 15 seconds approximately. If I've driven to work in a spirited manner, I get out of the car and get my bags out of the boot before the engine is shut off.
When I arrive home I unlock the garage and put the car in, so typically the car is sat for a couple of minutes there.
If I've driven for a couple of hours to another destination, the car tends to have about a minute after a long motorway journey.
Some will agree, some won't but for me giving the car time to 'settle' is a must.
I do use Start Stop, but only when I drive in heavy traffic moving car lengths in minutes (maybe once every few months as I work shifts, lucky me!). If I've been sat there a few minutes and made little progress, the engine has had its cool off session and only then do I use start stop.
What I find quite strange in the S Tronic is how it all happens so fast, I struggle to believe the starter motor has disengaged by the time the car starts moving.. incredible really. Another bug bear with my S Tronic, when pulling up gradually in slow traffic I have had it 15-20 times where the engine cuts out at say 4mph.. In turn you lose all steering. Now that I don't like, another reason why typically it's off even in traffic situations.
