    A3 2.0tdi - leak from fuel pump & diesel in engine bay

    Picked up an A3 2.0tdi on Monday and it has a fuel leak from the top of the fuel pump under the bonnet.

    This has led to fuel splashing all over the engine bay - car is back at the garage I bought it from (a Merc main dealer) to be sorted.

    Am I right in thinking the auxiliary belts will need replacing as they will have been contaminated with the fuel?

    I'll obviously expect them to steam clean the engine bay & anywhere else covered in diesel.


    Anything else I shoul dbe getting them to do / check?

    Thanks.

    Dealer has just called and said they have replaces O ring on the fuel filter and are going to keep it over night & give it a run to check it has solved the problem.

    They have also steam cleaned everywhere.

    So is it the fuel filter or fuel pump that was leaking?
    I had the high pressure pump gasket go and that was leaking diesel and making the car smell awful.
    The gasket cost under a tenner and its about an hours labour.

    I thought it was fuel pump, but maybe fuel filter is on top of fuel pump?

    Front left of engine bay next to the washer bottle, has 4 (IIRC) pipe going into the top.
