Hi John. Nice to see another Irish based x300 owner! I'm based down in Kenmare, just in case you ever find your way down south. Whereabouts are you?
As for your non start issue. Given that you have no lights and the fact that it did start at one point, it looks like something intermittent that you may have inadvertently disturbed/rectified during your investigations.
I'd suggest an electrical connection, most likely an earth strap. There are several in the engine compartment and also the earth strap in the boot at the battery should be looked at. Earths may "feel" fine, but should be examined, undone, cleaned, and tightened.
There is also a cut off switch which can be easily reset, just by pressing a button and this switch is behind the front footwell panel on the passenger side ( I think) If not, check the drivers side, but others will chime in.
Hope this helps and do keep us posted.

Hi John, and ye, don't get me started on tax!! I drive tour coaches during the summer, here and in the UK and have passed Glenbeigh a million times doing "The Ring".
As to your problem, if your battery is any way suspect, you will have problems starting and you will get erratic dash lights, what's sometimes called the "Christmas tree".
These cars are very power hungry and power sensitive, so anything below par will cause issues. You say your battery went flat, but owners on here, myself included, have left their cars parked for 6-8 weeks at a time and it starts first time. Your battery shouldn't drain so easily.
Also, it's normal for the power seats to work without any ignition, that's how they are set up.
So, you have to check for a battery drain. If you have a multimeter, check across the battery terminals, ignition off, and you should show about 12 volts (and then with the engine running it should show around 14 volts)
If something is drawing power, voltage will be lower, so then, systematically pull fuses, one by one, checking voltage each time, and if voltage increases, then you've found what's causing the drain.
A bad earth can also still have similar results. As can bad connections at the battery.
Try a jump start from a known GOOD battery, and best to jump it at te battery as opposed to using the positive terminal in the engine bay.

small world i am in Glenbeigh not far from you ,it`s a wierd problem i have power to the seats all the time even when key is out of ign. the batt goes flat after a few days now it won`t start .i messed with it and it started then next morning nothing and when you turn the key the red air bag light comes on and the orange bulb failure .might be a job for maguire and patterson LOL .I have looked at this forum before and noticed your car and that it was in ireland and felt sorry for you with the cost of tax here ,its a joke .i will undo all earth connections and clean and tighten again and see how we go .

A common factor here could be the Body Processor Module.
Among other things this controls exterior and interior lighting and one of the outputs enables the starter motor. Without this signal the car will not crank. In UK spec cars it is located on the passenger side behind the glove compartment.
