Help please! I am looking for some evidence of other S4's that have had this recall effected on their car - has anyone had done, or got evidence that work has been done to replace the exhaust manifolds on their S4? I believe that this applies to pre-facelift only, but I am not 100% on this. I am praying that mine may still be covered by the recall and want as much weight behind my claim as I can get! Cheers in advance.
