Idling Problems?
« on: 10 April 2009, 17:25 »
My Idling seems to have gone lumpy also the Revs rise then drop when stationary. Is this a TDC issue?
Only noticed it today, power seems to be ok, maybe a slight MPG drop but hard to  tell to be honest!!!

No warning lights?

MAF maybe  :undecided:

Best bet would be to get it vag-com'd (VCDS) but if it is the MAF they don't tend to generate a code in general.  You need to monitor the air flow on a run to see if its OK.

With MK4's a low tech way of testing the MAF was to unplug it.  If it ran smoother when it was unplugged then that was the problem.  If it didn't make much difference then it didn't really prove anything.

I still have 3 months left of warranty, recently bought the car so havent transferred those details over as of yet.

Is it safe to drive the car?

It is a little early for a MAF failure but you never know.  They are the work of the devil.  Could be something completely different too mind, I'm just speculating

Under warranty?  Happy days  :smiley:

Probably is safe enough to drive shortish distances - but don't sue  :laugh:
