    I'm struggling to find out as it looks like they changed various things mid 1998, so depends what side you are. Phone up your local audi dealer and give them the reg number, they'll be able to tell you for sure.

    Alternatively, look under the car around about the drivers seat, if you can see a lambda, there is your answer...
