my s4 has randomly started idling at 1100 - 1200 rpm
i've checked all the hoses i can get to for leaks, the recerc valves are seating nicely,
i've cleaned the throttle flap and reset it.
the only fault codes i'm getting are the EGT sensors (supprise supprise lol ) and an intermitant lambda heating fault.
the car idles smoothly drives ok, although you can feel a slight surging at very light throttle.
any thoughts?
