Yaris diesel glow plug issue

Hey, I've got a 2003 Toyota Yaris diesel with only 25261 km on it. The preheating lamp won't switch off, and there's an error stored. Sounds like a glow plug issue. Anyone seen this before?

I have a Yaris too. Sounds super familiar. If the preheating lamp stays on and you're getting a fault in the error memory, it's probably a glow plug. They're key for combustion, especially in cold weather for diesels.

Thanks! Do you remember the specific error codes you got? What symptoms did you notice before you knew it was the glow plugs?

Can't recall the exact error code, but the symptoms were just like yours. I'd get it checked by a workshop to avoid more problems. I had them replace all the glow plugs, and that fixed it.

Thanks for the help. Took it to a shop, and they agreed. Cost me 440€ to replace all the glow plugs. Appreciate the insight!
