Before I start a search anyone know what can cause an over boost fault code and runs in limp mode. Happened for the first time in 4 years today. Thanks for any input. First frosty morning? but didn't through the fault until it was up to temperature.

if your is a VNT , the solenoid actuator can be the problem , it's the solenoid with the paper filter on the bottom behind the air box
