Laguna glow plug issue

Hi, I've got a 2014 Renault Laguna diesel with 122823 km on the clock. The preheating lamp won't switch off, and the error memory shows a fault. Seems like a glow plug issue. Anyone experienced this?

A 2014 Renault Laguna diesel is experiencing a persistent preheating lamp issue, indicating a potential glow plug fault. The problem is associated with rough idling and decreased fuel efficiency. The suggested solution is to have the glow plugs checked and possibly replaced at a workshop, as faulty glow plugs are common in diesel vehicles and can lead to these symptoms.

Did this summary help you solve your problem?

Sounds familiar. I had a similar issue with my Laguna. If the engine light is on, could be a faulty glow plug. Rough idle perhaps?

Rough idle occasionally, yes. And fuel efficiency seems a bit off. So you're thinking glow plugs too? What was the repair like?

Could be. Glow plugs are like the spark plugs of diesel cars, if they're gone, they're gone. Better get it checked at a workshop. I ended up paying 440€ for mine.

Thanks for the info. Appreciate the tip. I'll get it checked out at the workshop. Seems like the glow plugs are indeed the culprit.
