    Evening everyone!
    I'm after some advice if possible, I have a 3l by diesel a6 quattro 12 plate. I'm changinging the injector seals this wkend as one is leaking and I have been having a diesel smell in the cabin for some time,on inspecting around the engine be nosey I have found a pool of fresh diesel sitting on top of the engine underneath the fuel return pipes,obvious thoughts were a split pipe but that doesn't seem to be the case! Would explain why my economy has be a little poor.I'm going to look into it more but any further assistance would be massively appreciated many thanks luke

    You need to give it all a good clean with a solvent cleaner, Check all the pipes are tight. There is stupidly designed 'V' in the engine which tends to collect all sorts of **** and store it. Thats where the diesel HPFP is located and accessing it is a pain too.
    Also check the fuel rails and any connections to it are not leaking.
