XC90 diesel glow plug issue

Hi there! I have an XC90 as well and had a similar issue last year. The check engine light stayed on, and I noticed a drop in fuel efficiency. Turns out it was a faulty glow plug. Did you notice any difference in your fuel consumption or engine combustion?

Thank you for your reply. I appreciate the information. I have not specifically monitored fuel consumption, but I will pay closer attention. Could you elaborate on the symptoms you observed besides the check engine light? Any other performance issues?

No problem! Besides the check engine light and the fuel consumption, the engine was a bit rougher when starting, especially in cold weather. Given your symptoms and the error code, it's highly likely a glow plug issue. I'd recommend getting it checked at a workshop to confirm. Mine ended up costing around 440€ to repair all glow plugs.

Understood. I appreciate your advice and sharing your experience. I will schedule a visit to the workshop for a diagnosis and repair. Thank you for the help.
