I’ve had a fault code come up on my 2014 A200 CDI po29900. The garage have changed the boost pressure sensor and the turbo actuator, ran 3 pressure tests, it’s been on the diag system multiple times and the code keeps coming back engine management light comes on and goes into limp mode. When the light is off and the code has been cleared the car runs as it should until it gets to temperature. They are now at a loss as to what it could be.
Can anyone help I’m pulling my hair out.
Not even Mercedes could tell me what’s wrong. Unfortunately the car has been sold.
