    deleting fault code question

    Astra 1.9CDti 150

    Engine managment light came on so i took it to a garage (non vauxhall) who told me that it was my EGR valve. They sugested a good clean out. So this i have done but the engine managment light is still on.

    Does the fault code need to be deleted or would it simply just not come on if the problem had been fixed?

    If i need to replace the EGR valve then im confident enough to do it myself but same question as above.. Will it need to be plugged in to delete the faut code?

    Many thanks
    Richie

    some faults need do be deleted with a code reader (can be had from £25 upwards on ebay)

    but some instances they can be deleted by disconnecting the battery for half hour or so - but only do this if u have the stereo code at hand etc

    An easier way, would be to locate the ECU itself and unplug the 2 big plugs for 10mins or so - same effect as before, but no need to reset codes etc

    Have u actually cleaned the EGR yet? or u just thinking first

    Thanks for the reply.

    Yes i have taken it apart and given it a decent clean (using carb cleaner). And i will try your method. Vauxhall want £50 just to plug it in!! so i took it to another garage who told me it was the EGR, i also done a pedal test which confirmed the code so im pretty confient that its the ERG.
