Hi all, I have A6 2.5 tdi 2001 avant. eng code is AKN. Can anyone tell me if this is one of the engine codes with the "Chocolate" cams as ADAMSS frequently refers to? Further, Throughout loads of site research I cannot find any reference to any AKN code engines. Is it any good, robust etc? Only fitted to a few models perhaps? Any gen would be welcome. Thanks.
