Mk7 Stop/Start System - Issues and Questions

For the last two days I have been unable to get this function to work. Usually it defaults to being on unless you turn it off. I have turned the switch on and off several times, driven with A/C on and off. I have driven the car often enougn to know I have a problem.*I know some of you hate this function but i'm a fan of it. Anyone else had problems with this feature?

Man, many would pay for it, to get that to be switched off.

Out of interest, has it been hot where you are the last couple of days? I know with our Touareg, at one stage we thought it was broken, but then realised that it wasn't turning off because the aircon was running..

Are you meeting all of the prerequisits for it to function?

Maybe your battery isn't fully charged? It won't work if the car hasn't been driven for some time.

Is the car up to full operating temp?

Mine comes and goes — I suspect it's controlled by measuring the current draw and comparing it to the state of the battery.

It must always be certain of a restart — if the conditions are not met the engine continues to idle.

I've noticed that VW systems in general seem to maintain the battery at about half to two-thirds charge, which I've heard (though I've yet to see it proven) makes the battery last longer.

Thanks for the replies. Yesterday I was driving for 90 minutes so I woild hope the battery got a good charge. It hasn't been warm in SA so I've only used tne air some of the time.i am going to VW on Monday to get the waste gate clip installed so if it's still not working I will get them to check it out.

RTFM - Read the manual, there is a list of requirements that have to be met in order for the blue motion to work. If it's hot in the cabin, AC on high, heaters on high, battery voltage, moons of jupiter in alignment……...
