I also found that someone hadn't put back in the battery drain tube properly. Since the drain was installed correctly, the corrosion has stopped. Anyone know where the voltage regulator is and should it or can it be altered to a lower voltage? My ctek charger also seems to be at 13.7. I'm taking a keen interest in my electrics just now as I have a 1.4 amp current draw from the battery with ignition off. If I remove the 50amp fuse from the fuse box, the current drain stops completely. Anyone got a circuit diagram for tracing what comes off FL3

Check your background illumination isn't remaining illuminated around the light switch after the car is locked
