need advice on the up keep of the car or common problems

 

well all of this is what i had done to my 99 a6 after i bought it, definatley have the timing chain, waterpump and such checked out and make sure thats good.. otherwise if that goes your screwed...id check spark plugs, and depending on if you have a the 2.7T you should replace the coil packs, i dont have a turbo so i didnt worry about this, id also check for leaks andwhere under the car just to be safe, id also replace air with a K&N and fuel filter, i also replaced my plug wires, theres a few more things you can do as well but i cant remember them, other people will help and you can do searches. good luck with yours and hope it treats you well like mine is. mines got 180k miles and still runs like a champ, and purrs like a kitten.
