Vanos Wiring

F80Mmm · 01-08-2018, 12:30 AM

I just completed an engine swap and getting 2A7C and 3100 codes. I noticed both vanos have the same wiring connector. Which wire goes to the intake solenoid (top) and which one to the exhaust solenoid (bottom)? Thanks.

Updating for future searches, I switched the wiring and everything is running beautifully - no more codes. Be careful u have the right wires connected if u ever mess with the vanos.

They are different length. I don't see how you can mix them up.
