    OBD on Renault Megan Scenic dTi 1999

    Hi,

    I need some help. I´m trying to some OBD on my Renault Megan Scenic 1.9dTi from 1999. It seems to have an OBD2-Plug and the wireing looks like ISO9141-2. But my ELM237 with Scantool was not able to connect to my car. Does anyone know, which Protokoll was used ?

    Greetings,

    You can stop trying. Diesels did not have to comply with EOBD until 2004. The car is simply not compliant.

    I think it's more a case of the car actually complying with EOBD, but not with OBD-II,
    in combination with your OBD kit supporting OBD-II, but not EOBD.

    I have the same problem with my Laguna.

    Hi,

    To clarify the topics. Renault dti's engine are not compliant with any OBD standard (EOBD or OBDII). Renault's engine are compatible with this kind of product from dCi's familly but before 2004 you can only read DTC.

    Take a look on your customer vhicule listing
