Sounds similar behaviour to my previous TD5 D2 when the MAP sensor became very clogged. Only use a spray cleaner inside a MAP sensor because solid objects such as wire risks damaging the sensor. Your engine has 2 MAP sensors. |

I did try cleaning the map sensors back in December however I would imagine at least the o/s one will be contaminated with oil again due to the turbo.

Injectors need a clean would be my guess.

I have considered a possible cracked inlet manifold Stan. Would this give me codes though as the MAPs wouldnt be reading correctly?

Ok so i removed and cleaned both MAP sensors. The left hand one was very oily as expected. I also cleaned the intercooler pipe on this side of residual oil.

Hopefully the poor running will have been fixed for the time being. |

Cleaning the MAFs would be appropriate although if you have an IIDTool then you could compare airflow readings and compare left and right boost too. |

It's not unheard for one of the lower turbo hoses to fail. There are 6 in total. 2 are short near the turbo and 2 longer to the intercooler and the 2 top ones that always fail. You can normally hear a boost leak.

Cracked inlet manifold gives turbo boost pressure faults.
