    I have Astra 1.7dti that cuts out occasionally. Fault codes are P0370 and P0251. What do you suggest to take a look first, the EDU on the diesel pump or ECU on the top of the engine? Thanks!

    Normally never had problems with the spill valve ..

    Check all connector plugs on these vehicles first for hot connections ... This will be spill valve connector and another plug close to top ecu ...

    If no problem on these then check bottom EDU unit for dry joint first ...

    Default -12V vs GND

    Hi friends,
    I have the same problem with -12V (all -12V not only one in attachment), but I suspect that were marked by mistake - it should be 0V.
    Could someone confirm it?

    Can You Believe

    This is good thread

    Be carefull for having burnt joints and then you try to solder it ..................... .
    The unit might work for a day or a week and then bite you in the ass again ... (only for a simple dry joint ....
