Hi there,
Last year i fitted a new inlet manifold to my vectra cdti 1.9 (150) 58 plate.

Recently my engine management light has stayed on giving me a P2075 error, the swirl valves on top of the manifold look very clean with no wobble, I also replaced the EGR valve (at the same time as the inlet manifold) but admittedly the gasket wasn't great and the replacement gasket sent was incorrect but at the time when refitted no engine management light (Would this generate a P2075 if the gasket has finally failed?)


Any help greatly appreciated!

Thanks
