    Default VW Golf Fault code P2279 Intake Aire System leak

    Hi, my gf's golf has gone into limp mode and I scanned it giving the fault code P2279 Intake Air System Leak
    I have tried clearing the fault, which works but at 50mph it goes back into limp.
    Going to drop it into toyota(turns out warranty waste of time)garage now, this could be a split hose or something simple like that yes?
    I don't know enough about cars to find the leak..but don't want them ripping us off as we've just been there for another fault which was the dpf..
    any help on this would be appreciated
    many thanks

    Yeah most likely to be a air leak in the small vacuum hoses. Check the hoses to and from the EGR valve.

    Common problem, although unfortunately a pain in the arse to find sometimes.

    Get them to do a smoke test, not emmsion test, smoke where they put pressurised smoke in to the induction and block off the exhaust,To show leaks. Don't think there is any silver bullet fix for that code. Could be a air flow meter measuring low flow. Could still be a dpf issue blocked causing low air flow due to back pressure in the filter.

    Sorry lots of things could make this code.

    How recently did you deal with the dpf , did they replace it or run a recharge ?

    or run it for 40 miles in third gear , common way to fix dpf ,because what they don't tell you about these
    filters is that the need to be ran hot every so often or they clog up .

    Thanks to plug1

    Yes I sort of knew they would be taking the piss but gr8 wanted to take it back to the garage to see if it was under warranty, needed the car back for work so she just had it done..it's back there now but this time we know a little bit more about the problem having a code....Will see what they say today and probably take the car from there

    No option to do that just clear the fault..it's only one of those Bluetooth obds with torque on my phone..unless you know of a better software?

    Call from garage saying it was going to a specialist(otherwise known as Dane Vw up the road) if it even went there..said it was a different fault to the previous fault, which I know and that they had reset it and tested up the bypass, we took it onto bypass and back into limp at 50, straight back to garage where gf really laid it on..apologies everywhere..looking at it again today..I bloody did what they did with my Bluetooth scanner ffs..
