I'm asking this question for a friend who has an Audi A3 1.8 Turbo Sport T Reg. She had a problem where she couldn't drive over 20mph so she took it to an Audi Garage and had it connected to their test equipment. She was told that the problem was that it needed a new part. They called this part a fuel body. Can anyone tell me what this part is? I do know it is something to do with a carburetor. Many thanks.
