Lexus IS glow plug issue

Hey, my 2009 Lexus IS diesel is throwing me for a loop. The preheating lamp won't go off, and the error memory has a fault stored. Mileage is at 245337 km. Pretty sure it's a defective glow plug. Anyone else seen this?

Sounds familiar. I've got a Lexus IS too, though can't remember which year. Had similar symptoms a while back – engine light on, rough idle sometimes. Worth checking those glow plugs.

Rough idle too, huh? Was it definitely the glow plugs in your case? Any idea on the repair cost?

Yeah, turned out to be the glow plugs. Best get it checked at a workshop, as diagnosing without the proper tools is a pain. My bill was around 440€, including parts and labor.

Cheers for the insight. I'll get it booked in. Seems like I'm in for glow plugs too.
