    Sounds like an issue with one of the 2 lambda sensors. Mine comes on randomly too, mine has been diagnosed as an issue with the 2nd Lambda. Maybe someone here can tell me(us) the reason for 2 Lambda sensors.

    Emission light could refer to anything that affects the fuel efficiency.

    Anything from a sensor, to a poorly fitted plug (don't laugh, this happened on my friends 2005 Astra petrol).

    Ideally, you need to get the DTC's (trouble codes) read with any suitable code reader.
    If you know someone with tech 2, Op-Com, Vaux-com then they could clear the trouble codes. Then re-scan for problems,
    Without finding what is causing the light to come on, you can't really speculate on how to fix the problem.

    hi I have a 2003 2.2 sri ,on sunday after filling up, my emission light came on , ive read the code and I have p0141, rr o2 snsr , has anybody had this code , and if I change the snsr will this cure it , theres a breakers near me at sandiacre ,they have 3 sri's so I might try a second hand snsr first , although Ive seen vauxhall ones on the net for £38 so not a fortune but want to ensure it will cure the code , ive cleared the code driven it and then when I call up DTC's it says one pending p0141 but doesnt show emission lamp on dash , I may run the fuel out first before changing the snsr to see if this has any effect

    Makes you wonder if ASDA's reputation for crap fuel is true !! Like I said in the other thread, proper Shell unleaded and some redex and the light went off. The Mrs is still at work but am hoping bthe light stays off on her road home !
