Today I finally got around to trying to diagnose this problem. The car has sat unused hooked up to a CTEK charger for weeks because of this.
I did a parasitic draw test by latching the doors and letting the car go to sleep then testing fuses.
I started in the rear fuse box. All seemed good except F75 which was 20mv across a 5a fuse! I think I found the culprit! F75 says it's 'Audio system, navigation system' so I checked for any loose plugs in the rear of the car where I removed the navigation stystem that might be grounding out. Nothing. I unplugged the xtrons harness that goes to the front of the car. Nothing.
I looked up a wiring diagram but I might as well show it to a dog because he would make about as much sense of it as I can!
I don't know what to do next.
Oh and the LCM problems persist. All sorts of lighting issues.
