    E53 2002 X5 4.4 257k KMS P0021

    Hi Folks, wife came home today said the check engine light was on. I hooked up my scanner and a P0021 code came up Intake Camshaft Position Timing - Over - Advanced (bank 2).
    It's running fine slight rapid ticking coming from passenger side (sounds like an injector?) and only heard with the engine cover off. I erased the code took it for a quick spin vanos kicked in like normal and code is gone. (for now anyways)

    No oil leaks, thinking it is a solenoid to me, am I on the right track? I'm in full denial about the TCG as there is no chain rattle.

    Thank you for your advice and input.
    Mike

    Error code came back today, drove about 700 KMS since I erased the DTC with out any issues. The Engine is quiet and running fine. If it's the guides then it won't be repaired so hoping it's a solenoid or sensor issue.

    I erased the code again and will see if the DTC comes back.

    Thank you
    Mike
