Now I just need to figure out the CEL. Seems like the X5 is idling low, and there's a slight rhythmic gallop that wasn't there, but otherwise everything is working fine.

Did you do the "Crimping" procedure on the vanos? I think you are supposed to drive it 200 miles for them to break in according to the instructions. I don't know if that is your problem. Also, your computer will be in "learning" mode.....adjusting for optimum fuel air for your various rpm vs. airflow tables.

Do you feel more power at the lower rpms? Any rattles at all on start up? Glad you got past those coolant issues!

its very easy to be out a tooth that will set off the SES light. Put the scanner on it and see what code comes up. Sometimes it just one vanos bank and if need be you can adjust the degree timing wheel on the vanos to get it to work.
