I was getting occasional key reading faults. I always have a regulated power supply across the battery when I work on a car. Nige Cowie got it spot on, I measured 9.5V on the starter motor command wire at the ignition switch, I originally thought the starter motor was controlled by the comfort module or similar, but deciding it might be direct I eventually decided to check back and found 9.5V on the engine block....Dohhh. Broken engine earth wire.I'm still kicking myself. Thank you all for your input. Shaun
