    Seriously, a paid member with 1500 posts and your going to a garage to find your error code?

    Any symptoms or just the light? Paperclip test or pedal test should give you the code then it should be relatively straightforward from there... If thats no good where are you based? May be someone on here with a reader or op com that can help... Can't really see the point in paying a garage around 30 to hook up the diagnostics when you can buy a reader for around the same money...
    N.b. any opinitons expressed above should be ignored and considered 'ramblings', under no circumstances should they be relied upon...

    Sure am, I don't have a clue when it comes to stuff like this
    I've heard of the paper clip test, but don't know how to do it... I have no symptons what so ever, which is why I turned to this forum for advice straight away

    When you're ready I'll begin.....

    With keys out of ignition - press both brake & accelerator pedal at same time and keep them pressed to the floor....

    insert key and turn to 2nd click - ignition on but DONT START THE ENGINE

    Keep both pedals pressed throughout the procedure....

    the EML will flash just like previous models using the paperclip

    You will probably find the light flashes 10 times first then a pause then another number, a pause, another number, a pause then another number of flashes.

    I say 10 times for the first one as 10 flashes = a ZERO on the fault code and most engine related faults range from P0001 to P0999

    If for instance u have the following sequence

    10 flashes
    pause
    3 flashes
    pause
    10 flashes
    pause
    10 flashes

    this equals 10,3,10,10 which in turn equates to 0,3,0,0 or P0300 which in turn is "Multiple cylinder misfire"

    10 is the only number that becomes another number
    1-9 flashes remain a 1-9 code if that makes any sense

    Have a go and let me know how u get on.... if u cant find the cause of the code - do a google with the words "Vauxhall and Pxxxx" (whatever the code is) and see what it comes up with.


    I did this last night on a members car and it came up trumps....even when both my code readers didnt diagnose the fault (one ebay £20 special
    and the other £300 one!)

    If all else fails then grab ur self a code reader for future diagnostics.

    £25 will get u a good one suitable for standard OBD2 models like AstraG from 00-04
    http://cgi.ebay.co.uk/OBD2-KKL-OBD-2...2em118Q2el1247


    £30 will get u the same as above but with the addition of CANBUS applications such as latest generation of Vauxhalls ie Astra H, Vectra C etc etc

    I got P0400 (EGR Valve?)

    Hose leak or blockage, wiring, EGR valve, EGR solinoid, or the most expensive part the ECM.

    indeed that is EGR gas flow malfunction, either needs cleaning out (i do not do this btw), or replacing with a new unit, my preferred choice.

    Concur on the replace and not clean - check out Delphi units from eBay, steer WELL clear of cheaper unbranded versions, Delphi one is around £60 delivered, mine has been fine for a few months now, unlike the first cheapy one which threw the EML on within a day of driving

    This is what is confusing me, the car seems to be running fine?
    No performance issues whatsoever
    I'll take it to the garage and price up a new EGR valve
