    what is fault code P02040

    So,

    Audi dealer in France plugs in his VAGCOM into my A4 Avant and says gearbox knackered - 8,000 euros for a new one please.

    He says the Fault Code is P02040 - can someone please tell me what this code translates as?

    thanks

    You could try this site Audi P0726 OBD/DLC Error Code - Engine Speed Input Circuit Range/Performance I used this when my ECU went on mine. Strange but it says (P02040) code doesn't exist.

    Anyone any idea what this then means? Does it have anything to do with a failed gearbox?

    Could be the code is incorrect, all the codes listed on the site you linked are 1 letter followed by 4 digits so would guess that it is wrong.....

    Having a look at the fault code list I have found from this site http://www.vaglinks.com/Docs/VW/BentleyPublishers.com_VW_DTC_Table.pdf

    I
    f it was P0204 would relate to this;
    P0204 Cyl.4, Injector Circuit Fault in electrical circuit

    What do you mean "no use"??? They don't recognise the code or they won't tell you what it means??
