EGR not working?

(1/2) > >>

ReflexRob:
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?

Ricky123:
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?

MrACD:
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:

ReflexRob:
Cheers chaps - you are right I meant PCV, not EGR!  :rolleye:

Will check the dipstick method and post back.....

ReflexRob:
Ok,  pulled the dip stick.

Slight change in the way the car idled but no huge change....?
