    vw golf mk6 glow plug cylinder 2, circuit malfunction

    Hi guys,

    I have engine light come on and done diagnostics. It gives the code P0672.

    Would I have to replace glow plug? Very unsure of what to do.

    Also would anyone know the cost of replacing glow plugs on golf tdi?

    Is it worth replacing all if them?

    Any insight would be helpful.

    Easy to change (IF they don’t snap coming out) and only £100 a set genuine. There are three makes, Beru, Bosch and NGK and there can be set up differences so it makes sense to replace like with like.

    Thanks, I bought some from EuroCarParts (Hidria).
    Spoke to my local mechanic and they did mention might snap in the process hence why the labour charge is a lot.

    Would you know where the glow plugs located on a golf tdi?

    On the front of the head, you need a long deep reach 6 sided 10mm socket, preferably in 1/4” drive so you cannot apply excessive torque. When you get one out, tell me what it is and private message me your REG number, I don’t know how good Hidria glow plugs are (made in Slovenia) and I get the Hidria number to be H1 339.

    Thanks, I will see where they are but personally Iím not going to do anything. Donít want to mess anything up. Very unusual and awkward way to fix this. Iím just going to leave this with my mechanic but worried in the long run donít want any faults appear.

    Thank you for your input in this very helpful.

    Thanks Keith,

    So overall wiring connector / wiring loom need to be checked or replaced. Donít know really what Iím up against. Seems to be more then just a glow plug replacement.

    I can’t see it being anymore than a new glow plug but there is an easy way to find out.

    If they cleared the code yes, a re-read giving the same code proves the point 99%.
