Hi , i have a 2003 Audi S6 4.2 Avant . I have now got a problem . The catalytic converter on the right hand side has gone and now brings up the engine management light .
The problem is i have been to all the high street places like kwik fit etc but none of them can supply a new one . Can you give me some advice please as i really am at a loss as to what to do . Thanks , Graham .
