Egr cooler plugged or bad egr?

Did you check if is not derated ? I had similar problems hard to diagnose caused by a bad EGR valve, low boost power,black smoke. I took the truck in 4-5 Volvo shops and they were clueless, because was not throwing egr fault codes and not doing it all the time, and finaly a mechanic here at Volvo in Cambridge Ontario replaced the EGR valve just to see if will make a difference , and this was the isue.

 

that code is egr temperature-data valid but above normal operating range, you could have a bad egr temp sensor, stuck open egr valve, i'd also check the egr massflow sensor and sensing ports for plugging, and like i tell everyone, black smoke is caused by either not enough air... or too much fuel... if they installed your turbo and moved your vgt actuator over, they possibly didnt calibrate the vgt actuator properly?

 

What was the issue with the turbo etc. ?

 

Did you replace vgt actuator aswell? Low boost can cause if you cac leaking. Pressure test your cac and check if no leaks. Also check if your doc is not plugged, if you have exhaust restriction you will also loose boost. Do 7ou have pyro gauge? What are turbo exhaust temps?

 

1150 can damage your turbo. Your egt suppose to be like 700max going hills. Pull your doc chec if it is not face plugged. If your truck has def, check if its not plugged def pipe and def doser.

 

I was wondering if there was an issue with the DPF due to the picture you had showing the oil in and around the turbo. Oil leaks back and gets into everything from the Turbo back. When you can give an update as to what the outcome is. Good luck
