Fehlercode P401 1.6L Diesel

  • Ist der Ausbau aufwändig? Denn eine Reinigung in ausgebautem Zustand sollte funktionieren.

    Das würde mich auch interessieren. Der Kühler ist ja doch unter recht vielen Teilen verbaut.

  • Sometimes the engine service yellow light appears on my speedometer. I remove the map sensor on the Intake manifold and clean it thoroughly with electrical contact spray.After this work the spy disappears. Other times it stays on indicating error P0401. By deleting it with OBD the light disappears. I read that this is probably caused by the clogged EGR cooler.If I only purchased the metal radiator marked with the code V29007672 I would clean it and then have my mechanic install it instead of the one I have, could this solve the problem?I would clean my old radiator and keep it as a spare part. It might work?A mechanic friend of mine works at Opel and he told me that there is an updated version of the radiator, does anyone know the code Thank you.
