2014 a4 2.0t help
Hello, I have recently been having issues with P0506 & P0303. I have changed the plugs and coils hoping that would fix it, but it did not. I then changed the PCV Valve and I am still having the same issue. I did also clean the throttle body & checked for vacuum leaks, which it doesn’t have any, does anyone know what might be going/have had the same issues? Thanks I’m advance!
