HI,
Similar situation here.. 2000 s4 tip car. 101k on the clock, Misfire on #5, Changed the pack, no change, Cleaned the plug, No change, Cleared the code, no change! I am the general Manager of a large Chrysler Jeep Dodge store! But I love my european cars period so I drive them still. I owned a store for 7 years and then sold. If any body will help me through this I will promise you need a true wholsale value on a car of some market reports as to what the cars are doing in the auction feel free to ask. I know you have better things to do than hold my hand but this sucks. The damn car runs rough and its as fast as a fricking ford festiva!! LOL!! WTF!! So its gonna be my daily driver and it needs to be what it is should be! I have a wrench at the store that is pretty savey with them. He owns VW'S and what not. Where should he go first or should I just roll into Audi and take it in the ***!!! Its shows a random misfire code. This happens a lot from what I see. I have unplugged the MAF and no change in the way it runs.
