EGR not working?
« on: June 25, 2015, 07:04:34 pm »
My 2005 GTI with 49k on the clock doesn't idle very smoothly,  the needle doesn't move but you can feel rough idling through the floor.

I removed the oil cap with the engine running and it made a gurgling noise but the engine still ran smooth.

Do I have EGR failure?

I'm sure tfsi' don't have an egr??   :confused:

Common poor idle faults can be pcv, coil pack, spark plug and even carbon build up on intake valves.

Is your engine management light on?

That usually would point to the PCV, probs needs replacing.  When I took out the oil dipstick (2 seconds) it started spluttering and running rough.  So if yours doesn't I look at getting that changed to start with  :happy2:

Dont know much about this however my 06 gti was running bad, rough idle, car would gain rpm at idlle to 1400rpm and back , turned out to be a 180 degree pipe from pcv easier to show you

The pipe cracks easily and doesnt seem to seal very well causing idle issues
