Hi,
the heater plugs should glow very quickly, are you sure they are all working good and have good contacts.
My 1.9 sometimes waits after start button pressed, but only 2-3 seconds.
lf the engine is a little tired or air in the system, that wouldn't help either.
Let us know how you get on with it.
Good luck
Bob.

Like the hair dryer idea know a few farmers that do that :)
Only a delay of 5 seconds or so for glow plugs yesterday and it was minus 3. Starts up straight away with a bit of smoke. Modern slim plugs don't need the 10-15s that the old Peugeots needed. Faulty glow plugs flag up a fault code usually on these but I would still check they are getting power. Not sure of it's location but there must be a control box with a temperature sensor that could have gone haywire...
