Ok peeps been having a play with my car today. I thought lets see what happens if I disconnect the actuator ie pull the vac pipe off it.
Well I did this and went out of a slowish drive and shock horror it made the spanner light come on, no suprise though lol. Fault code tested which gave me P1106.
So just though not every one might be needing to do the earth mod as this also brings up the fault code.
Just thought I would share my findings
