rough idle
anyone have an idea on where to go from here. 2002 a4 3.0
just started to stumble/rough at idle in park or drive,i have no loss of power no hesitation when driving,no cel . told the dealer about it when it went in for an oil change (like to keep my book up to date) only codes showing were for random multiple misfires. they changed all 6 coil packs under the coil campaign at no cost to me. it is still rough at idle,took the maf out and air filter gave them both a good clean
still no better.
goin to take it back to the dealer as they didn't fix the problem
but if anyone has any ideas in the meantime i would appreciate it
thanks sorry this is so wordy

Re: rough idle
Ok... i have 2007 A4 Turbo Quatro ... I have replaced the coils, done the seafoam, all under warranty. Still dealer says its normal. So I went out and bought Lucas Octaine Boost, and Wynns engine tune up. Put it in ....and it calmed down. NOt eliminated it but calmer now.
My only issue is i can't afford to do that for every tank full.

Re: rough idle
thanks for the input guys i finally got it sorted.
crankcase breather hose setup was screwed up it was not venting the pressure out the engine which was causing it to stall.
dealer only part coudnt find one anywhere on the web $600 for a few feet of hose and a valve
ouch!!!!!
