So I've been digging into this over the last week or so and I think I'm getting close.

Problem 1 was definitely the DVD nav unit never sleeping. I replaced that and the load dropped from 0.6 to 0.2A.

Problem 2 is something on Fuse 73. According to the fuse panel this shows up under Telephone, Navigation, Display Unit... so one of those. I know its not the bluetooth unit as disconnecting that had no significant effect. I'm assuming its what's referred to as the TCU which is known to be problematic.

What I can't figure out though is where on earth the TCU is/ what it looks like or a part number or something. I've tried searching on here and Google but so far no luck.

Anyone know what exactly runs off fuse 73?
