Only when my engine has reached full operating temperature and my speed is around 80 kmh with OD enabled, a whine begins that is high pitch and is linked directly to throttle position even if speed is the same.
This can be verified by pumping the throttle in high gear and it's very clear the whine is related to the throttle position.
I bought the car with the whine and it has only gotten worse since.
I theorize it's the injection pump because what else is linked to throttle on an old diesel? Also I have made sure all belts are tight and changed all oils for the car.
I need to get this fixed because it's driving me insane on my everyday trip to work. So the main question is what the heck could this be with the throttle position and how do I fix it??
