I have a 2012 q5 3.2 145k miles on it. I did the upper cam chain guide and tensioner on each head a few months ago roughly 1500 miles ago. Now I have code p0017 camshaft correlation bank 1 sensor b. So passenger side exhaust cam. I swapped cam sensor positions still same code. Swapped vvt Solenoid positions still same code. If p0017 is only code I have does it seem likely cam timming is off on exhaust side? Or is there anything else it can be? Was thinking about ordering new camshaft adjuster sprocket for end of exhaust cam. Anything else I should check before I pull oil cooler to lock crank in and check timming? Motor runs fine, no hesitation, start right up, no rattle. Code comes on soon as I drive it down road won't come on at idle but if I clear and drive down road same code is back
