disclaimer: this may be elementary for some

using this link ( http://forums.audiworld.com/a6/msgs/607831.phtml ) i was able to change my spark plugs. it took about two hours but i stopped to eat and had to run to auto zone b/c i couldnt find my 10mm wrench. this is definately a do it yourself job. just go slow and remember to plug back in all sensors, caps etc.
the only variations on my a6 from the diy spark plug link;

the coil packs on mine had 2 10mm screws that had to be removed (instead of just twisting them). this made the 2 plugs toward the front of the car a PITA to remove. the other four came out no problem.

this can be done with simple hand tools. if any one needs any help with this, feel free to pm or email me.
i also scanned it after i was done. no fault codes were found
i feell pretty good about doing this myself and also with the money i saved.

thanks AW and audiforums
good luck
