    Big Problems, Engine management light and interior lights

    I have a 1997 1.6 16v Astra and the engine management light comes on randomly but car runs fine apart from when its ticking over it sounds like its going up and down just a wee bit and my interior lights are staying on all the time, doors all closed and car locked and still on, any ideas on either?

    SIlly question maybe in regards to the interior lights, but have you tuned them off? IE push the head-lights switch in?

    Always the best question to start wiv but yeah had done that, just got it fixed, turns out that the lights in the roof are dodgy and if you touch them then that happens, thats prob why theres neons in the footwells instead of a bulb in the roof. Still stumped on engine management light though

    Best bet is to get it along to a Vauxhall garage and they will plug it in to their diagnostics system which will tell you the fault code. Saves a lot of head scratching.

    or better still (and cheaper) do the paperclip test to read the fault codes urself


    The OBD port for your mk3 should be in the fusebox itself as shown in the picture below

    you need to bridge pins 5 & 6 and watch as the engine management light flashes (do this with the ignition on but not running)

    you should end up with a series of flashes and pauses

    for example:
    10 flashes
    1 pause
    3 flashes
    1 pause
    10 flashes
    1 pause
    10 flashes

    10 flashes = 0
    all other flashes = that number

    the above would therefore = 10,3,10,10 or 0,3,0,0

    in turn this would give u a code of 0300

    a quick google of P0300 would return the cause as a random multiple cylinder misfire which in turn would usually relate to a dodgy coil pack.

    Obviously the above code and cause is just an example but have a go and let us know how u get on

    Good luck

    Pic of OBD Port:


    Personally judging by your initial post Id say its the EGR and ICV giving the problems - therefore a thorough cleaning of the throttle body, EGR & ICV with a can of trusty carb cleaner (£3 from a local motor factors) should see everything return to normal.
    Id advise all owners to do this about once a year so even if its not the cause - its defo advisable to do it
