no sounds daft but it is ur break light switch above the pedel u wont have any break lights when it is flashing just push the pedel with ur hand in front of pedel at the top just fiddle with it till it pops out if no joy with that it will need changing hope this helps

most time when glow plug light come on your glow plugs not working.check fuse if fuse is good problem is in glow plug relay.

when the glow plug light keeps flashing.Thats telling you that you have a fault with one of the sensors.Take it to a garage and get it checked out with a diagnostic scan.

Sounds like it is telling you that you need to get a glow plug replaced that is not functioning properly. Have a reputable shop let you know which one it is.

obviously there's a problem with the system... your best SOLUTION is take it in for proper DIAGNOSIS.. ya think?

brake light switch is very common problem mounts on brake pedal linkage under dash

faulty brake switch at foot petal

Check the glow plug thermo sensor...found in the cylinder head.
Unlightly anything wrong with injector pump.
Good luck

they are giving you bad advice... that light is basically normal ... your glow plug light... if the motor starts ok ... it's nothing to worry about .... unless i've missed something and you are saying the light stays on... basically with a diesel you turn the key on... wait for the glow plug light to go out ... then start it.
