the 403 and 405 are more then likely from having my egr valve unplugged but what are the other one and what might be the cause of this it pretty much did this out of the blue?!?!?!
Here is the codes:
P0299 Turbo/Super Charger Underboost
P0341 Camshaft Position Sensor Circuit Performance (bank1/1 Sensor)
P0403 Exhaust Gas Recirculation Circuit Error
P0405 Exhaust Gas Recirculation Sensor A Circuit Low
P0478 Exhaust Pressure Control Valve High Input
However I can't help you on the diagnosis.
