problem with Vauxhall Vectra 2.2diesel Elite

[Josh1994]

So the flashing light will tell me that it is a electrical fault etc, how will i know?

Just an idea to try that, pinched from Corsa C forum.

and that light is not "definitely emissions" it will come on for electrical faults, ECU faults and low fuel pressure, misfires, timing faults. All experienced by myself with the corresponding fault codes to go with them.

Its on inlet manifold, 10mm bolt holding it on cant remember which side
