If the lights work, why did you buy a new battery that you didn't need? A car like an Audi A6 can't be fixed by 'guessing'. It is what I call the 'Let's try replacing this' method of car repair. Modern cars need electronic diagnosis using the OBD2 port that is provided for that purpose. You need an auto electrician, his pro grade scan tool computer will show where the problem is. Did you check fuses and relays with your digital multimeter? Also, when you disconnect the battery, the anti-theft system needs resetting. https://www.google.com/search?q=audi+a6+reset+security+system https://www.google.com/search?q=mobile+auto+electrician+near+me ..

Audi Provides online tutorials for many of their car features via a free service called Audi Technology Defined. Simply select your car (Audi A6), your tutorial, and get set to learn! You can find it here: http://microsites.audiusa.com/ngw/09/experience/technology/?csref=inid_technologyAn owners manual is always a good thing to have. I would contact a local dealership and have them order an owner's manual for you as well.

Erasing the codes doesn't fix the problem. You will need to find out what is causing the misfire. What EXACTLY is it doing when you crank it? Does nothing? Just turns really slowly? Turns at regular speed and nothing else? Turns, tries but won't idle? Comment below and I'll see what help I can give you.

call a local auto parts store and ask them if they can provide you with one for that old of a car

Needs to be scanned for fault codes form the transmission module. Need to start there first. If it is a CVT trans you will most likely need a new trans.
