Ok so i have a S4 Avant i am restoring as i got it very cheap, the car fires up ok which is a relief though it has some leaks. my main first concern is a rattle in the exhause somewhere near the front, how can i tel if its the Cats or the heat sheilds? and if its the Sheilds how easy to sort it is and where is there location etc etc.
any help really appreciated
