This is a common failure on the M52TU and M54 engine. This would be on any BMW with the above mentioned engines. E46 3 Series. E39 5 Series. X3 E83. X5. The P0344 fault code is for camshaft position sensor A which A is refering to the intake camshaft. My video goes over step by step the process to install a new sensor to fix this common failure of the intake camshaft position sensor.
