Few days ago, message 'Gearbox Faulty' came up while driving, gearbox when into neutral by itself and I cannot select gears, engine running fine. Switch engine off and restart, manage to engage gears again, got home after this happened 4/5 times in 2 miles ( sorry to the people Mine threw an engine fault message with the service light staying on after I parked the car on a slope for a few hours. No issues while driving over 50km home though. Once I got home, shut down the engine and left it for about 5 mins before restarting - engine fault message gone. My 58 plate diesel VTR Grand Picasso keeps coming up with an 'Anti Pollution System Faulty' fault whilst driving causing the engine to cut out. A warning light will also come on in the top left of the screen. The car will always start again straight away, but that isn't much help if you're hurtling down a motorway. dw5f.
