  • S6 missing on 2 cylinders

    Hi guys,

    My car is dead on cylinder 3 and 5.
    I've checked all 5 coils and plugs and the spark is good, all the injectors are working too.
    It fires up but if you disconnect injector 3 and 5 there is no difference in idle.
    I'll do a compression test but the motor has only done about 400km.
    Any ideas on what to do?

    You said the spark is good. Have you tried swapping the power output stages for the coils to see if different cylinders are affected?

        How did you tested the plugs ?are you 100%sure that under the load they are producing good spark ?
        Just swap them around and see if the fault is migrating with them .
