I plan to run a vanos test on my M5 in the near future, as I too have a mild warm idle fluctuation after restarting and a exhaust drone change at highway cruise. It's been doing this since I've owned the car, but really don't bother me. No codes or warnings, frequent oil changes, and runs great. If this is a result of not OK vanos solenoids, < 0.8v, how long have some of you continued driving under these conditions before replacing solenoids? I've read into a couple threads on here about these exact symptoms that members couldnt explain a reason for and many replies were that these symptoms are normal or have been going on with their E60 M5 since day one off showroom floor of for the past 50k + miles...
