    Ignition coil fault code on astra

    Check the plugs & connections to the coilpack. Make sure nothing is preventing the coilpack from seating properly.

    What code is it showing?

    Think the code was p0354 but don't hold me to that

    Might be worth checking the cam sensor, if that plays up the sparks will be stymied.

    Also check and clean and WD40 all the ECU connections.

    Thanks Taurus, also any way you could show me a picture of where and what the ecu looks like on these engines? Thanks

    As you look into the engine bay it's on the right hand end of the engine.

    Have a look at this link - it ought to show a photo with it labelled - 1.6v 16v Whats in your engine bay? | Vauxhall Owners Network Forum & Club - Insignia | Antara | Mokka | Adam | Ampera | Vectra | Astra | Corsa¬*| Signum | Zafira | Meriva | Tigra | Agila | Vivaro | VXR

    Looks like one of the cylinders has either worn valve stem oil seals or a stuck / damaged oil control ring on the piston ring. Pretty common on these engines to have the misfire from the plug getting gunked up with oil.

    Would a compression test show that?

    Also if it was that mate why would it throw up a ignition Code?

    From what i read the ignition fault shows up because there's a misfire, but the misfire is caused by the plug getting stuck up with oil.
    I could be wrong but there was a discussion on some other forums where that was said to be a common issue

    The question is - is the misfire due to a plug fouling, or is the plug fouling due to a misfire (ie lack of current to it or a dud plug) - either can result in a fouled plug.

    First thing to do is to try a new set of plugs. Then keep a close eye on the cylinder that's fouled and see if the new plug fouls up.

    A compression test won't show a weak oil control ring or a leaking valve stem seal. The former will show smoke on acceleration. The latter can be checked by getting it warm, let it idle for a couple of minutes, then get someone to blip the throttle (not massive revs) and watch the tailpipe. A puff of smoke that clears quickly is valve seals.

    Put a new set of plugs in, try it and then tell us what happens.

    It's just had brand new Bosch plugs in this morning mate, there is no smoke from exhaust at all

    I think it may be a fault causing a injector to stop and causing oil on plug, I just wish I knew how to check properly

    You could try swapping the injectors round and see if the fouling follows the injector, and if the fault code changes.

    But if it is still misfiring on brand new plugs then it's not a fouled plug causing the misfire.

    U have just put a earth from ecu to the battery and it seems to have stopped the mis fire but the code remains, I checked the fouled plug and it was fine sane as the rest but I haven't been far in car

    Anyway the earth helped but hasn't sorted it I can only reset the eml by leaving battery off
