how do I diagnose my camshaft chain issue P0011

What is your question?

Car is new to us. Previous owner says he replaced the camshaft chain and the tensioner. To troubleshoot, I've replaced: 1) oil and filter with new 2) Camshaft position sensor - note that the snap on the connector is broken. I super-glued connector in place 3) Camshaft position solenoid I have the camshaft chain cover off currently. I have little experience with this, but things seem ok. Nothing to compare that to, though. Previously, the p0011 code would take 20 or so miles to pop up after a battery-disconnected reset of codes. Now, with the engine making a new noise, the code pops in just a few blocks. I don't see what might be making the noise.

How long has your 2006 Volkswagen Passat had this problem?
