Kuga Auxiliary Heater Issue

Sounds familiar! I have a Kuga as well. Had similar symptoms with my parking heater last winter. Did you check the glow plugs? That was the culprit in my case.

Glow plugs, huh? Where are they located, and are they easy to get to? I'm not exactly a master mechanic, but I'm willing to give it a shot before taking it to a shop.

Okay, so I had the exact same issue last year. My local workshop confirmed that the glow plug was defective. They replaced it, and it cost me around 440€. If you are not confident doing it yourself, I'd recommend a workshop.

Thanks a lot! I suspected it might be something like that. I'll book it in with a workshop and mention the glow plug. Hopefully, that'll sort it. Cheers for the help!
