I have had this message flashing up car goes into limp mode but after parking car and restarting car is ok again low mileage HDI MK2 I have taken the inlet manifold off and done a complete carbon removal from the inlet manifold and the inlet ports in the head. Injectors where removed and stripped down cleaned and rebuilt. Whilst the inlet was off I decided to fit the 3 electro valves that are located on the rear of the inlet as it would be impossible to change without removing the inlet again these where OE parts and finally I have fitted a OE Map sensor. So with doing all this work I was hopping that this would get the car running without the Engine Fault message but unfortunately it has not. So the question is where else should I be looking in order the rectify the problem ?
