Stop/Start

[macmillions]

Just a quick one,
On my Superb Greenline the stop/start function sometimes doesn't come into play, so when I apply the handbrake and select neutral the little stop/start symbol appears, but with a line through it. Why may this be? I understand it will be the case when the engine is cold, but after a good hour's trip it sometimes does it too.

Stop/Start is one of those things that seems to have a mind of its own... There are a lot of things that need to be just right before it will work.. Mine is a DSG so when I come to a halt it works just off the brake pedal pressure, hard press it activates, light press it keeps running..

In the handbook it gives you a list, but suspect a few more things are taken into consideration Lol

Yeah I think there are things to do with operating temperature, steering wheel position, DPF regeneration etc. Quite a complex set of checks it must complete before deciding it's ok to commence the stop/start function!

In fact I have been out in mine today, did 12 miles and the stop/start did not work.. Lol
