Switch off the ignition, exit the Viano and lock it using the remote plip. Walk away at least 100m from it and wait at least ten minutes. Return, unlock the Viano and start it as normal. If it starts perfectly, your problem may be that the engine immobiliser programme is becoming 'confused' when the ignition is switched off but the vehicle is not being fully locked down. Activating itself, it cannot 'de-activate' until it has received both 'lock' and 'unlock' signals from the remote plip. This programming error exists across several vehicle makes that share the same immobiliser manufacturer at that time of production.
