Changed out the packs and BAM, no more problems...Especially with our 2001 model, go to Audi and get the right coilpacks cause the ones you can get at local parts stores are garbage.

after you cleared the codes and replaced the coilpack the misfire stayed in cyl 3?

i noticed on my car that when the MAF went bad, and i immediately unplugged it, the car would still run like crap because the fuel trims were so messed up already. it takes a little while to get back to normal. clear the codes to reset the fuel trims, unplug the MAF, then start the car. if it still runs like that its not the MAF.
