Hi,
I have joined as I have only just got a 500L MPW Lounge, 1.3 Diesel multi jet, 7 Seater. I am impressed with the MPG as I am getting approx 45MPG and I only travel 9 miles each way to work.
Although I travelled 50 Miles each way yesterday on a day out with the kids, the Start/Stop didn't work. I tried turning it off and back on again, still nothing!
It seems to work, even on short distances when I top it up with fuel but there was over half a tank.
Is there anywhere in the vehicle to store the parcel shelf when all seats are used? Other MPVs have somewhere to store it.

Stop start will only work if there is enough power in the battery etc. There is no where to store the load cover which is a pain in the bum!

Late answer but someone may need it.
That shelf/bar fits behind extra seats when they are up. Its little tricky but fits perfectly.
