    Try pre warming the plugs first just in case, (swith on ignition wait for glow plug light to go out, switch off and repeat)

    Possible fuel blockage, coil pack,, glow plug etc etc.... be honest a multitude of things this could be, so a diagnostic would be best... see below

    I suggest looking at uk-mkivs.net, there will be much better info and help there, Plus many people with the same issue

    There is also a listing of people who own the diagnostic software,

    Sometimes they charge a few beer tokens some do it for free for the kick of helping a fellow golf owner

    hope this helps

    is there any power to the bus bar , try a jump lead of the plus terminal onto the end of a glow plug hold it there for five seconds then get in and try to start it, if it starts then its either glow plug relay or theres a 50 amp fuse, my was on the bulkhead in the middle of the car, my car is a mk3 golf tdi, but yours will be same procedure on starting

    I had a similar problem with my old Mk3 tdi, it turned out to be one of the relays in the fuse holder under the dash board.

    I cant remember which one, but if its intermittent you might find that flicking these relays with your finger may get you by until you find a replacement

    glow plugs maybe?

    It's unusual for a diesel to start from cold, but not from hot.

    In my book , "intermittent" nearly always means "electrical".

    squirt a little starting fluid in the air filter and it should fire right up.

    girl above, there are no spark plugs on a diesel

    Get some easy start, spray it up the air inlet. This should work!!
