07 CL 550 FAULT CODE P0022
It recently just got out of the shop but my check engine light came on and it read; [NOT DEFINED] CONTINOUS CAM SHAFT ADJUSTMENT (LEFT): INCORRECT POSITION OF THE INK\TAKE CAMSHAFT (P0022)
Before sending it to the shop again is this something worth sending it back ? Or a possibly easy fix. I have been doing as much research as possible but getting different answers/solutions.
Thank you in advance.
