I have a code that is coming up:
009571/P2563 - Turbocharger_Boost_Control_Position_Sensor_Circuit
Once I have been travelling at motorway speeds for over about 15 minutes, if I then pull over, put the car in neutral and leave it ticking over. The MIL starts flashing after around 5 seconds.
On short journeys around town the light doesn't flash.
Can anyone help?
I have already had the actuator, pressure sensor and N75 valve replaced.
