There should be a positive terminal under the hood under a red cap as i am assuming ur battery is not visible, use something steel on the motor for a ground, sometimes the batteries to newer vehicles are under the rear seat so if ur having trouble finding out how to even hook up the cables i would look under the hood for the terminal first, will probly be in a random place then if u cant find that or the battery check under the back seats

The oil filter is placed on the left rear side of the engine. See pictures below:




After engine cover removal:


In the above picture the oil filter was removed, (green arrow).

Your A6 Quattro's battery is located in the engine bay, in the center up against the firewall. It sits beneath a dust cover, so you will need to remove that to access the battery

The most common place for it to come in when its raining is in from the Rear wheel (the welded seam is split) or around the top and running around inside under side of seat. Or if it comes in when stationary then it the door rubber is not tight enough.

It ccan be done but you need a tool to remove the trim not all the trim is replaceable and you can buy from the dealer the parts you need to do it but you don't want to do it yourself unless you don't mind getting your paint scratched up.

You need to access bolts that are bolted to the floor, disconnect wiring, move the seat forward and look from the rear seat down under, you will see bolts..

The rear seat pulls out easily.  Grab the front of the seat with fingers under seat on driver side and pull up hard.  do the same on the passenger side and it will unclip.  Then you can move the seat around to get to the buckle.  Install by inserting rear end in first and lineing up the metal tabs w/ the female plastic inserts in the floor and push down hard until it snaps into place.
