Post by: Ma22789 on February 28, 2015, 07:23:06 am

Right so I have this code p2279 leak in air intake system lower limit reached I need this code gone so rtec niki can go ahead with mapping my car I have changed the inlet manifold the pcv all the gaskets and pipes Iv had 2 smoke tests done and I have removed my runner flap delete and put the flaps back in with the motor and the code still manages to come back im on the verge of selling up  :sad1: when I done the smoke test its loosing pressure so I'm guessing there must be a leak somewhere rite ?

I had this problem for ages it drove me nuts!!!!
My smoke pressure tests didn't loose any pressure though!
You checked your dv?
Checked all the pipes are firmly in properly?

Mine was caused by my gasket on my downpipe from the turbo!

I have had the manifold of 4 times and dv is good and was yours the metal gasket between the turbo and exhaust ? I never would have thought that would throw up that code ?

Did you replace the gasket on the inlet manifold?

Only others I could think of are:

-air intake pipe to turbo
- DV split
-intercooler pipes
- PCV where it connects to inlet mani (or boost gauge tap if you have one)

Yeah that's the one!
Replaced it and it never came back! It fell apart in my hands :/
Strange I know, only noticed it was gone when trying to look for the leak!
