I got a p226c yesterday it’s probably the turbos need replacing. I got my truck from a smaller dealer (not Nissan) 😟 gonna take it back today they’re pretty good at making things right. I wonder if Nissan would still cover it because of their extended warranty’s or not because I didn’t buy it from Nissan just asking to get some input. Good luck buddyI've had the same codes thrown for two years for the turbo actuator. I've been back and forth thru the dealership for bandaid fixes (i.e flash ecm clear codes) it will throw check engine light then I'll lose power to 25mph max. I went to buy DEF last week and service manager said they just added turbo extended warranties. The warranty info is just above my fingers on page. I have an appt next Monday to let dealership confirm issue and order parts for repair. I'll update the process. I hope this helps someone.
