Here's what they posted for a cluster test for an E46:
Have you tried the cluster test?
1. Hold Trip Reset while turning ignition key to on position
2. OBC should show "Test"
3. Repeatedly press Trip Reset to select function 19.0 to unlock all of the features
3. Wait for display to show "Off"
4. Depress Trip Reset for 1/4 second and release it
5. With no delay press Trip Reset repeatedly until 2, or 2.0 maybe, is shown and stop. All the gauges should go through their full range of motion.

I'm thinking that the dome light controller and the failing cluster are likely related, though I don't know the virtual hierarchy of these modules... The dome light only turns off when the cluster resets.
You think the E46 procedures are the same for my E88? The cluster works perfectly fine when it's not resetting, all of the needles work, displays, ect ect. It's so strange.
I've read that otherwise undetectable battery issues can dead leg these cars, maybe it's time for a new one.
