    Emissions light keeps coming on?

    It keeps coming on at random times and staying on. I've tried resetting the ECU by disconnecting the battery a couple of times and this seems to keep it of for a day or 2 but it comes back on. The car appears to drive normally.

    Going to book it in to Vauxhall but I wondered if anyone would know what it is - likely to be a dodgy sensor?

    Pop under yout car and check the second lambder sensor conection. Its located just after the flexi section oin the exhaust. Mine came unplugged and then the light came on. If it has come out just plug it in and the light will go out
