Losing essentially zero oil, not measurable on the dipstick at least. There currently is not a noticeable amount of coolant in the oil... and there wasn't when I brought it in for service 6 months ago either. During the service, the coolant was drained & replaced when the oil cooler was replaced - mentioned that in my original post.

Can you post a pic of your coolant bottle with the cap unscrewed. The red fluid that VW uses does get brown. I would pull a dram vial worth and see if you can see sediment separate or aq/organic layer form.
I would flush the system with hose water. Empty system and flush with DI water. then back up with that special vw coolant.
Used coolant (non contaiminated) can be disposed of down the drain at some water treatment plants. Ie. Phoenix. You will need to call the your water treatment plant to confirm or pay for it at the local solid waste facility. But that is just the waste coolant. It is perfectly legal to let the flush go down the drain (3% of containments is what the EPA reg allows iirc). If you really don't feel like that you can collect the flush and let the water evaporate and just throw away the solid salts that are left behind.
