Hi, I bought my first q30 just over a week ago, it's a 2016 1.5d with only 8000 miles on the clock. Drove car a couple of days with no problems apart from stop start not working but just thought car needed a good run but noticed my stop start would rarely work and if it did work it would only do it once. Also the symbol would disappear completely off the dashboard and you would have to use the key and restart engine to get symbol back on. I've had the battery changed and it's been linked to the car so car knows it's new but still have same problem with symbol disappearing off dash but stop star might work 3/4 times fine before this happens. Anybody else had this happen and managed to fix problem.???
