I've got a 05 ram 2500 cummins and I have some codes, one is for key program (dealer said they can't fix it) Fan speed, fan speed control, waste gate acuator. Dealer said all codes are related to the waste gate so I spent the $600 on a waste gate and installed my self, all codes are still there. I've deleted them with 3 different code readers. Any one have a issue like this?

Thanks Regert

 

If you deleted and they came back, either they're really stacked up in there, or there is still a problem.

 

what process did you use to remove the codes? As said above though, if you did remove them and they came back then you still have an issue

 

^^^^^ That or your PCM is bad.
