Hi all, need the brains trust again. My koleos (2.0 diesel manual) has brought up this fault code.
DF004 turbocharging pressure sensor circuit.
Short circuit to ground or open circuit.
Originally it went into limp mode. It would come out of limp mode by restarting it, however engine light stayed on. Tried to clear the code, wouldn't clear. So after some research bought a brand new map sensor from eai. Problem solved, or so I thought. Fault code would clear. But after running the engine an switching off it would come back but without engine light. After the 50 km trip home the engine light is back on. All the vacuum lines look good, but I'm not actually sure how to test them. As do the turbo piping.
Where do I look next?
