Hey Gents. Last spring was having the above ECU code show up repeatedly. Dealership sent a guy out a couple times, last time changed the actuator on the variable geometry turbo. 150 hours later and it’s back at it. Will go off every 10 minutes for 3-4 hours, then go away for a day or two. Driving me nuts. 3200 hours. Do I need to replace the whole thing?
