Question about 2004 Land Rover Range Rover
I have had the same issues with the ignition switch, you can replace the switch, but in my case the solution was actually a new battery. The early L322 Range Rovers have a very high power drain with the vehicle turned off. I have never found a good solution for this except for a main battery cut-off which is not a good idea due to computer issues. If you have periods of time when you do not drive for over 2 weeks a cut-off would be worthwhile.
Load test your battery, and replace if necessary. A number of warning lights can come on when the battery is disconnected (or very low in charge), with a good battery they usually will go off after the vehicle is driven for about 100 yards.

I'm sorry I have to disagree with some of the comments above. The early HSE's do not have a heavy battery drain provided that they are not faulty. Vogues may have a large drain but the whole point of buying an HSE was to avoid dreadful ergonomics that can with the navigation touch screen and to get a second multi-format CD player instead of the archaic tape drive in the Vogue! It wouldn't surprise me if that navigation unit is a source of trouble but your 2004MY HSE doesn't have it. Mine is ten years old, still with the original battery and starts first time even if it has been left standing for a month. However, there are two issues with this vehicle that you should be aware of: First there was a software fault in the BMW sourced air conditioning. The system failed to acknowledge that the car was switched off and if the ambient temperature inside the car rose it would switch on the fan to cool the ecu. So if the car was sitting in the sun in a car park for any length of time it would flatten the battery. New corrected software should have been loaded by the dealer at the first service after about mid 2004. If this wasn't done that might be your cause. The second point is that the batteries in the L322 have memory and you may not be getting a full charge. To recharge one properly you have to put it on a special charger that discharges it completely and then recharge it from scratch. This takes about 24 hours. Other than that I am afraid I can't help you. Good luck.
