Mk7 GTI Camshaft Adjuster and Sensor

This page details some parts that I replaced related to the Camshaft Position Sensor and Adjuster.

In my case, the first sign that something was off was the engine becoming louder at idle.

Later a CEL would pop up reporting an issue with the camshaft position sensor that was accompanied by the engine running rougher.

I was logging the car at the time the issue threw the CEL and it was apparent something was off since both the intake and exhaust cams reported position began to be off from normal operation:

Rather than replace parts piecemeal to determine what was faulty I decided to replace the sensor identified as faulty by VCDS and also the Camshaft Adjuster Magnets and the Camshaft Adjuster Valves.
