Yup, had some rage under solenoids and the removal vent really smooth. Did not remove engine cover only airduct. It is tight but there is enough room to wrench and have one hand down there.
Cleaned both solenoids with brake cleaner and switched them out. Have not been able to replicate the vanos code on the 4-5 WOT pulls I have made after the cleaning/switch.
Thanks again for a great DIY on this awesome forum.
