2015 ram 2500 deleted and tuned.
72k miles started getting codes p00AF, p003A and p0472.
I'm not getting the u code that says loss of communication. Could it be just the actuator without U code?
Gone to local shop he deleted codes started back up popped right back up and immediately said new turbo. It will be $4850 to replace.
Now injectors knocking at low throttle, high throttle no knock.
No new codes.
Please help if possible.
Thanks
