    wired up wrong lol Wiring diagram if you look at the top left of the diagram fuse F10 you must have a permanent live there it powers the main double relay for the engine/ecu or as you recon the key barrel is causing it to be live

    It's 100% faulty ignition barrel as heater and rear screen intermittently were not working new barrel and all working and even switching off but thanks for input
