Hi. Yes, the gearbox disengages and the D on the driver's display goes from whatever gear I was in D3, D4 etc, to just D. I've tried different drive select modes including Dynamic but it still does it. I saw something on Google where they said to go into the Driver Assist menu and untick the "Intelligent Freewheeling" but mine doesn't have this option. The only way that I can stop it from happening is to drive around with the gearbox in S mode all the time, but doing 30mph in 3rd gear at 2000 rpm gets tiresome really quick. I was hoping that maybe flicking the gear stick over into M mode might teach the cat that I don't want it to keep free wheeling but it just resorts straight back to doing it as soon as I put it back into D. It's driving me absolutely mad, to the point where I just want to get rid of the car.
