RJ Car will always start but will not always stop. If I stall the engine the dash sits there lit up and making a buzzing sound but the start/stop button fails to turn off the ignition. The immobiliser seems to be working fine and as expected. All other switches seem to function ok when driving. If I disconnect the battery and reconnect then the ignition remains off and I can restart the car, but then have problems switching off again. At the weekend I drove to Compton Abbas for breakfast. Car would not turn off there so disconnected battery and reconnected, this was after fitting the new start switch. Drove home and same thing. I am wondering if the problem is related to the lights being on or heat as I have popped to get fuel without the lights on and it has worked fine. Nick
