I have a 2003 A4 3.0 with 169k miles on it. It is currently sitting in my garage unwilling to start and treat me to the driving pleasure you know these cars offer. Early in our relationship, maybe 20k miles ago, I had the common issue of difficulty starting after fueling. Browsing helpful forums such as this, I fixed the problem by replacing the n80 purge valve and charcoal canister. I haven't had the same problem since when it comes to fueling. However in the past couple months I've been suffering similar difficulty starting as I did after fueling before. The difference now being, it occurred randomly and unrelated to fuel stops. It would take a couple tries to get it started, after the initial normal first attempt, I would hold the throttle down about 3/4 and she would fire and clears its throat with some high rpms. Then it would run normally. Well about a week ago I tried starting it and it did the same crank, fire to ~1500rpm and die. So I tried pumping throttle on second, third etc attempts. After a few attempts it wouldn't even start but just crank. And thats where I sit currently. So I bit the bullet and ordered the RossTech Vagcom cable. Here is my auto scan result(I deleted modules w/o faults):

Upon seeing that cylinder three misfire, I replaced that coil pack simply because I changed the spark plugs a few months ago and a coil pack was only $20. Unfortunately that didn't work. I've also reprogrammed both my keys after replacing their batteries. I reprogrammed them using my VagCom and they are working to lock and unlock the door. The batteries were failing and I had to reprogram them previously due to weak signal so this should account for the immobilizer faults. Also there is no immobilizer light flashing while cranking. My 02 sensor faults have been there since I bought the car.
Any advice is greatly appreciated!
Thank you
