Golf gti fault codes

[Kee1994]

My revs are hanging around 1500rpm for about 5 seconds. When coming to a stop and when just revving


Fault codes are leak in air intake system p2279 and idle control system higher than expected p0507

Also I have a ramair airfilter fitted

Any ideas guys ? Thanks.

I had this issue when I put my oversized ram air induction on, make sure your clamps are real tight on the connections, i impact wrenched mine to make sure and I never seen it again... although mkvs do rev hang a bit anyway from factory, something to do with emissions i believe.
Someone will correct me if I'm wrong

Yes, I think one of your jubilee clips isn't tight enough or it could be a faulty PCV

Correct    Most DBW engines do that. It delays throttle closure slightly to burn off any residual fuel in the cylinders. It seems to be misunderstood as ‘throttle lag’ on a lot of forums but DBW can go from 0 - 100% way quicker than a mechanical throttle
