I also have the AC whine on my 2010 D5. My specialist says the bearings are gone in the compressor but it works for now. I had it regassed in September and it didn’t help at all.

The lumpy cold and start up noises I resolved with replacement engine mounts. I’ve replaced most of the suspension and engine mounts as much of the rubber had spit or gone brittle. My car is much better now. The manual gear change is still very stiff on cold mornings until it has warmed up but I can live with that for now.
