Hi, I have a 2006 Defender 130 which has recently become temperamental on starting. About 40% of the the time it starts fine while the remainder all you get when you turn the key is a soft click as if you have zero power in the battery. I normally reset the immobilizer and after 1 - 2 mins of turning the key the car seems to fire up no problem. The non starting is becoming more frequent, I have charged the battery and changed some of the fuses which needed doing. Any suggestions on how to resolve the problem would be really helpful.
