Welcome to the forum.

1 or more of your glow plugs has failed.

What's the engine size and model of car?

 

[nortac44]

Take the connector off the relay in the engine bay and measure the resistance to the individual plugs. Replace accordingly.

As its on your own car and the relative cost of glow plugs, I would replace them all as a set.
