Hey Velly. How did you get on with this problem? Mine is doing the exact same thing.

Yes Spike we did, found out something was wrong inside the head....basically Number 3 cylinder was leaking and the ECU was full of water (drain holes in tray was blocked)
So fitted a new ECU and changing the engine.

Do a leak test...make sure all the valves are closing
