NEED HELP! cold start 2A7A, 2A79

Hi All,

We've been chasing these codes for awhile. Its something about the the cam alignment when cold.

We already tried cleaning, replacing, and swapping both vanos solenoids but they still come up.

I've done some research and heard it could be cam gears, vanos actuators, cam ledges, or sensors. I read even oil weight could affect this.

Looking for any help or insight because besides the sensors the above solutions are all pretty expensive routes. I can't chuck money at this thing with out getting it fixed.

Thanks in advance!
