I asked the question when I picked mine up, but there is no way to turn it off permanently unfortunately
I struggled with it at first but after a few weeks I have tuned into it and find it great now, I linlve seeing how high I can get the Eco timer!
Afaik, it doesn't use the starter motor. It's actually the alternator that does the starting, that's why it's so silent and quick. However at a grand a pop, it will hurt when it does go wrong!
I managee to get my engine off for 27 mins of a 1hr journey in London!
Ouch, that will hurt! Let's hope that it is a Citroen part that will stand the test of time then! Interestingly I have just dropped mine off to try and have a rattle sorted out somewhere at the front, and they have loaned me a manual DS3 which has the stop/start system. This is much better as you have to knock the car out of gear and release the clutch before it stops. Maybe it would have been a better idea if Citroen had made it so that the ETG6 had to be placed in neutral for the stop/start to kick in? Anyway, I'm sure I will get used to it and appreciate the benefits in time.

I think it's spot-on as it is, but it does jump if you're heavy footed and it's not quite stopped.
If you're queueing downhill you can roll without even starting as long as you keep a tiny bit of pressure on the brake.
I like the " creep " function on the Pug stop / start

The Berlingo one also creeps - the dealer told me they didn't in the past, but they added it recently.
