    SAI 16795

    Hi Gents,

    I have had an odd cold start issue for a while now. It turns over fine, then i get a mild shaking, revs fluctuate it settles down and runs fine. This never happens when its warm.

    Today i got a fault code, 16795 which points to the SAI and i believe this explains the issue at cold start?

    I believe this is an issue with the vac pipe coming from the N112 valve to the SAI ,based on research correct me if i am wrong.

    My question is where can i find this vac line/N112 valve?

    BFB engine code by the way.

    Thanks again!

    FAO James, or anyone else who knows.

    The combination valve fig.3 in the above diagram; I can see the vac line running right but I cant see the vac line running to the left. How far down the back of the valve is it?

    Thanks again

    bump.

    I have had a good look at all the SAI pipe work and all seems fine. I can only presume its either a faulty N112 or Combi valve (egr?).

    How could i check both of these parts?
