Hey guys,
I know I'm new here, but I'm having some trouble with my 2004 545i, I was hoping someone might have had the same problem.
Background:
107k miles
Automatic
Other issues:
Obd mentioned low coolant temperature, which didn't repeat after being cleared
Car loses 1 qt of oil every 5k miles
Mechanic wants a lot for diagnosis, for taking off the valve cover, I want to see if anyone has had similar problems and if it's a serious problem enough to justify thousands in repair costs
Any ideas?

I am 99% sure it's your water pump. The plastic impeller and the bearing are done. I'd get that replaced right away. It's not a bad DIY if you wanted to do it yourself. I think the re-manufactured pumps are around $170. Oh, and get a fresh serpentine belt while you are at it. Good luck!

I'm sorry if this is a dumb question, and I'm not at the stage where I can do a water pump myself, maybe a light, oil, top off fluids.
It sounds like a lifter issue, are the two sounds similar and easy to mistake? Its coming from the front/top passenger side of the engine.

try taking the belt off and run the engine for a bit. if the noise is still there, get a cheap $10 automotive stethoscope and start probing for where the sound is coming from.
