> I've just been going over my new (to me :o) '94 S4. One thing you've
got
> to give Audi - they are consistent! The S4 has the same problem as my
200q -
> the aluminium composite heat shield over the rear muffler touches the seam
> on the fuel tank. In the presence of sand, water, & road salt, this sets
up
> a nice electrolysis cell which accelerates corrosion of the tank seam and
> the heat shield.
> On my S4, there was a pile of wet sand trapped between the tank and
the
> heat shield. The heat shield has a large hole corroded in it and the tank
> seam was rusty. The seam is now painted and the shield pulled away from
the
> tank. It might be worth a look for listers in northern climes.
> I also note Audi has retained the seized rear caliper guide pin
feature
