Hi Guys,

I have been in the market for a 96-99 2.8L A4 for the past few weeks. Have
called quite a few of the ads in my area (seattle) and it seems like every
other car has a check engine light that will not go away. WTF is up with
that? Usually, that is some emission control BS - O2 sensors or EGR - all of
that garbage is dealer-only and will run $1-2k to fix... What I am wondering
is why are these problems so common on these cars?
