    I got one of these off Amazon to diagnose a cold starting issue with a Megane II 1.6 petrol.
    KingMansion ELM327 WIFI Wireless OBD2 OBDII Car Auto Diagnostic Scanner Adapter Reader for iPhone4S/5 iPad4 iPad mini iOS PC: Amazon.co.uk: Computers & Accessories
    We hooked it up to the car doctor app on an Ipad and while we got all sorts of interesting and sometimes incomprehensible real time data no error codes showed.
    I took it to an independent specialist who found and cleared half a dozen codes.

    The question is do I need a better app or a better OBD code reader?

    And before any one is tempted: "you need a better car" is not an acceptable answer or option at this time :)

    I've never used the one you have so don't know how to use it. Someone more savvy with Apps might be able to help more.

    This is the one I use....Sealey VS8800 EOBD Code Reader: Amazon.co.uk: Car & Motorbike

    This does most code reading jobs I need to do on non Peugeot/Citroen stuff...my Peugeot/Citroen diagnostic kit is very sophisticated, but this does most jobs for me (except ABS and Airbags). I have plenty of mates in the diagnostics business who have all the gear for that...we help each other.
    Some of the Renaults need the Renault specific kit for code reading.
    Some Vauxhall codes can't be read with the Sealey kit, but Vauxhall have a system of code reading that doesn't need the reader (you press the accelerator and brake together and count the flashes of the spanner light)

    Not all fault codes are stored on ecu's open via the ODB2 protocol. Manufacturers store some codes on a variety of other ECU's connected using a car network (MOST) etc and using their own protocol.

    Try Torque on Android but don't you'll get too far :-/
