    Mk5 1.3 CDTi Estate cold start issue

    Hi there

    My MK5 1.3 CDTi seems to have an issue form starting cold. It's very slow off the mark and feels like it's close to stalling.

    I have these fault codes
    P0683 Glow Plug Circuit Low Voltage B-038
    P0683 Glow Plug Circuit Open B-038

    Is my first port of call changing the glow plugs?

    Looks like it mate, if you had not put up the fault codes i would have thought it would be a problem with the pre heat system (glow plugs).

    I agree

    Without those as you say points to the pre heat system.

    Now i'm a complete noob with diesel's the astra is my work horse and my other car is petrol turbo. Is there a specifc type/brand of glow plug i should go for and is it a straight swap like spark plugs for example (be gentle )

    If you get the right glow plugs then it will just be a straight swap.. Be carfull when removing them or tightening them as they are prone to snapping if you put too much pressure on them. It may be worth soaking them in WD40 overnight before attempting to remove them. I had one snap in my old 1.7 DTI and it was a head off job to get it removed.

    I'd go to vauxhall and buy originals. They will probably be less prone to snapping due to being better quality.

    Spoke to my nearest Vauxhall dealer.

    Glow plugs priced at £12.50 each.

    On changing the glow plugs will that cause the fault code to go or will i need it removing.

    If you go to a half decent garage the might remove the codes for you, however if you dont there will more than likely be someone on here who can help out, then also you could take your bttery off for X amount of time and see if that works only thing is you will need your radio codes.
