Volvo V70 diesel preheating lamp issue

Alright Volvo gurus, I'm pulling my hair out! My 2007 Volvo V70 diesel (with only 57398 km on the clock!) is throwing some weirdness my way. The preheating lamp on the dash just won't switch off, and I've got an error code stored. I'm guessing it's a glow plug issue, but wanted to check if anyone else has seen this before I start tearing things apart. Is it safe to drive or am I risking further damage? Help!

A 2007 Volvo V70 diesel is experiencing an issue where the preheating lamp on the dashboard won't switch off, accompanied by an error code. The problem is likely related to faulty glow plugs, as indicated by rough cold starts and extended cranking times. It is advised to have the glow plugs checked and potentially replaced to prevent further issues, such as damage to the starter motor.

Sounds familiar. I had similar symptoms on my V70 a while back - the constant preheating light is super annoying. Does it struggle to start, especially when cold? If so, it's almost certainly the glow plugs. Have you noticed any rough idling or engine misfires?

Thanks for the quick reply! Yeah, the cold starts are definitely rougher than usual. It cranks a bit longer, and there's a slight stumble for a few seconds after it finally fires up. Misfires, no, I haven't noticed anything specific. So you really think it's just glow plugs then? Any chance it could be something else related to the fuel system?

Based on my experience, that rough cold start is the giveaway. While other things could be contributing, the glow plugs are the most likely culprit with those symptoms. I'd suggest getting it checked at a workshop to confirm which one(s) are faulty. I ended up replacing all of mine when one went bad to avoid future headaches. It's probably best to get it sorted sooner rather than later to prevent any potential damage to the starter motor.

Okay, brilliant, I appreciate the insight! Glow plugs it is then. I'll book it in at the shop. Just had the quote through - 440€ including parts and labour. Ouch! Thanks again for your help – knowing it's probably 'just' the glow plugs makes me feel a lot better!
