Did you have this issue before you started changing stuff like the Vanos Seal or did you have this issue after you started changing parts.
If you having this issue after your repairs, it is something you probably did. Go back and re-check your work. Follow any procedure that is outlined for the parts replacement. Don't assume that you can just take out a part and put back in a part.
If you were having this issue before replacing parts, you need to do a little bit of more diagnostic. A DTC will point you to a problem the computer is seeing, it does not identify a parts to be replaced.
In your case, the cause of a P0014 DTC trouble code may be caused by one or more of the following:
Incorrect camshaft timing
Wiring problems (harness/wiring) in intake timing control valve control solenoid system
Continuous oil flow to VCT piston chamber
Failed timing valve control solenoid (stuck open)
