I have had the reduced engine power light coming on for the last 3 weeks. I replaced both cam shaft position sensors with Bosch parts went away for a few days then came back. So I replaced both vanos solenoids two days ago with an off brand (okaymotors) from Amazon code came back within 60 miles. Now it is throwing the code every time I start the car pretty much not sure where to go from here if anyone could give me some guidance it would really be appreciated.

 

Possible causes, and recommended actions

 

Just got the P0015 error last week. Wondering if you had any other symptoms (rough idle, hard start, engine noises)?

Hoping in our case it just is the solenoid (we swapped the sensors and still got the exhaust sensor error so not likely them that are failing).
