Hi, I also have the same fault with my 2l C5 petrol. When I accelerate hard it sometimes cuts out. I start the car back up and the anti pollution fault comes up with the engine and service faults. The car still runs fine though. To clear the faults all i do is turn the ignition on and off 5 or 6 times, lock and unlock the car, and every thing is back to normal, no fault warnings. The Citroen dealers have no idea what this problem is, but I think I might replace the lambada sensors and see what happens. Regards Chris
