Hey all,
I recently rebuilt my top end of my Z4M (including VANOS) and I'm experiencing an issue.
Started the car fine and it idled smooth. Took it outside my neighborhood in low RPM and it feels a bit sluggish and hesitant but the minute I give it aggressive throttle it goes into limp mode and throws me the code P1644 and P1554
Clearing the codes only gives me P1554 until I push it into limp mode again... then P1644 shows up again.
Gonna double check my Cam timing but wanted to get all of your opinions so I know what to look for when I open it up again. Maybe someone had this happen before? Any advice appreciated!
Thanks!
