Title: Zafira eml and poor running
Post by: Jimbob on 11 May 2017, 17:10:39

Zafira has a P2279-5B code, it comes on normally when coasting, not accellerating then stays on.
Ive no power low down, until about 1800 rpm when it acts normally.

Ive had this once before a few years ago, and replacing a worn swirl flap actuator rod was the fix (from memory).

As it happens a service was scheduled in for this week anyway, which consisted of new air and oil filter, new oil, (9000 miles old) along with cleaning out the boost sensor and cleaning the egr.
I also remembered similar symptoms when the DPF sensor pipe was holed, so checked it, wasnt convinced on its health so replaced the old run of mixed hard plastic with various repairs with a single run of fuel hose.
Also visually checked as much as I can see, and nothing poking me in the eye as wrong.

Ive used the com of op to operate the swirl flaps - externally appears fine, a good sharp movement, and also can hear the egr valve move if I actuate that.

None of this has helped and the symptoms persist, clear the light / codes and its back after a few miles.

Any ideas where to look next?

I have a reducing plate on mine.

The usual cause of this code is the EGR valve and occasionally a split inlet pipe (with the engine running actuate the turbo and check the hoses)

I don't suppose it makes much difference which to be honest as both will reduce the flow.

I like the before EGR method, in theory it should keep the valve cleaner if there is less shite going into it
