    Astra G X18XE1 Engine management light...

    I've literally just bought a 99 Astra G, I've been driving it around a bit and on my last journey the engine management light came on straight away (not a good start!). The engine seems to be running fine, it's got plenty of power and revs okay although it does feel a little "juddery" however that could well be my perception as it's very slight.
    Is there anything obvious to check? It's really not convenient to get down a garage to have it plugged in although I have a 300mile journey home from uni coming up in the next couple of days.

    There is one thing I noticed: On the coolant reservoir, water is gushing from the top left-hand pipe (when looking from the front of that car) in to the bottle. Is it normal for water to circulate from that pipe? It might seem like a strange question if it it but I don't remember noticing it on my last car.

    Much appreciated.

    first of all - do the paperclip test to self diagnose the ECU trouble codes

    do a search on here using the word "paperclip" and youll get a brief how-to i did not so long back....also check out www.topbuzz.co.uk for more details on this procedure.

    Cleaning the throttle body & EGR valve is a very wise step and id bet (not much tho lol) its the EGR valve thats the problem.

    Thanks for the very helpful reply.

    I did the paperclip test and am reading:

    **********-*-***-**********

    I believe that works out to be code 13 which is the oxygen sensor being open circuit.

    From searching on here am I right in thinking it maybe linked to the lambda sensor?
    I'm looking at this thread if anyone else sees this with the same problem:

    Update: I've just been for a drive and the light didn't go on (after I reset it) so I'm guessing it's a loose connection. If it comes on again then I'll try to trace it.

    the coolant "problem" you describe is normal, that is the coolant return from the throttle body which ensures it doesn't ice up in very cold weather

    yup thats P0130 fault - 10,1,3,10 = 0,1,3,0 = P0130 - Lambda bank 1 sensor

    replacement o2 sensor for your XE1 model is part number 90536393 and a quality replacement will cost a little over £60 from here: http://cgi.ebay.co.uk/Vauxhall-Astra...2em118Q2el1247

    In comparison, vauxhall will charge about £150 for this part.

    check both ends of the sensor - the elec end and of course the ceramic tip end - unscrew it out of the boss and clean it up and see if things improve.....if not then a replacement will really be called for im afraid.
