2010 MBZ GLK 350 4MATIC "DTC" CODE #1204

DTC code 1204: Constant adjustment of exhaust, camshaft of left cylinder bank in direction "Retarded."

Car becomes non-drivable. It almost feels like your car is at its last stage, but don't worry - it's a fast and easy fix that will save you a lot of money, and will not put a hole in your wallet or pocket. This is a magnetic camshaft exhaust side positioning sensor, that seats on the left front of the cylinder head (See image). 

Fix:

Replace the sensor and it will fix the problem. Sensor cost is $38 at retail.
