My wife has a 2015 Outlander Diesel (2.2) Auto, the car starts ups and idles OK, when trying to drive it will judder and not go above 15 mph, the fault code I got was P0106 - Manifold Absolute.
I checked and cleaned the Mass Sensor, but not difference,

Any ideas what could be the cause.

TIA

 

Is the inlet manifold blocked? especially around the port for the boost sensor pipe?

Check the air filter pipe to the turbo. They can crack right where it clamps to the turbo
