Error code P0299 turbo underboost
I now have the above error along with P2080 (exhaust gas temp sensor) the sensor was replaced a few months ago and seemed ok.
the oil change light is now on too.
So underboost is like a valve is stuck open for the turbo? Does anyone have any idea of what I should be checking- I have found no technical trouble shooting guides/manual for this car what so ever.
I will be changing the oil and filter this weekend, I can't imagine all 3 are linked? Im not even sure how underboost and gas sensor are but they appeared at the same time.
Any help is grateful.
