    A4 2.0 TDI no eml light showing when ignition switched on none start

    Basically im posting for a friend whos car isnt starting as the eml light is not showing when he switches the ignition on to start then car he had it read and came up with engine ecu car starts and light comes on after flicking the ignition on and off a few times is this common or is it case of a sticking supply relay or is it internal to the engine ecu.

    Any help would be grateful.
