H Guys,
I've recently got the P2279 Intake Air System Leak fault code on my 1.9CDTI 150 Astra.
I've searched the forums and various other sites and come across the below steps to take in resolving this problem:
Clean EGR and Manifold + Confirm EGR is working with 12V (confirmed)
Confirm Swirl Flaps are working (confirmed)
Clean Boost Pressure Sensor (done last night)
At the weekend I removed the EGR valve and cleaned it out. I confirmed the Solenoid was working by applying a 12V feed and I could see it opening and closing fine. (it was also fine before cleaning it).
The manifold that the EGR is bolted it was pretty clogged with soot, which I've cleaned out and re-fitted the EGR
Last night I confirmed the swirl flaps are working by getting a friend to rev the engine and I can see the rod moving to the side and the black plastic covers moving too. I'm not sure how Fast this is supposed to move as it looked pretty slow to me as the engine speed increased, but I take it that this is normal? with this fault code my car is pretty slow to rev past 2k anyway.
My next thing to try is to clean the Boost Pressure Sensor (when I find out where it is, down the back of the mani I think?) If someone has a picture illustrating the location this would be handy before I burn my hands trying to find it haha
My question is after I've done the above steps, what's next?
Also on my fault scanner (Torque + Bluetooth ODBC) it states that this fault may be something that the ECU may now allow to be cleared until X amount of drive cycles and the engine learns that the blockage is gone. Anyone know how accurate this is?
After clearing the fault at the weekend I drive 50 miles before it come back on and ever since now when I clear it I get about 1 mile and its back on again.
I'm going to put some Reddex through it because I've read that it sometimes helps, but I'm sceptical about this and my specific problem.
Any advice appreciated guys.:'(
