R56 PO54B Cold Start “B” Cam Position Timing Over Retarded help
Recently did an oil change, and added Cold and Hot side charge pipes. (During oil change I added Marvel Mystery Oil).
I started my car up this morning and got code PO54B.
Im thinking of cleaning VANOS solenoids. What do you guys think?
