Thanks for the tip. I ran a scan and got error code P0670 - Glow Plug Control Circuit/Open. Does this confirm my suspicion of a defective glow plug, or could it be something else entirely, like a wiring issue?

Error code P0670 indeed indicates an issue within the glow plug control circuit, lending further credence to your initial assessment of a defective glow plug. While a wiring fault cannot be entirely dismissed without thorough inspection, the error code, in conjunction with the symptoms, does point towards a failing glow plug. Given your vehicle's mileage (165864 km), it would be prudent to have the glow plugs inspected and potentially replaced by a qualified technician. The repair cost is likely to be around 440€.

Based on the information, the persistence of the preheating lamp and the error code strongly suggest a malfunction within the glow plug system. Before disassembly, I recommend a diagnostic check using an OBD-II scanner to ascertain the specific error code. This will provide more insight. Could you share the error code?
