I am new to this forum and am looking at used A4s (2002-2003). Are there any known issues (recalls, common problems, etc.) to keep an eye out for as I look at used B6 A4s? Thanks.

common a4 problems are coil packs and rear coolant flange is built like shit so you will need a new one every 50000 miles just to stay safe. sometimes the sunroof will act on its on or wont work when you need it to.all are easy fixes except the coolant flange which costs an arm and a leg to repair at the stealership. timing belt needs to be replaced every 60 to 65 thousand miles and that costs a hefty amount.
