Mini One heating issue

Alright, I'm having a heating issue with my 2011 Mini One. The rear window heating isn't working at all. I scanned for errors, and there's one stored, but I'm not sure if it's related. Also, the windshield heating doesn't seem to be as effective as it used to be. I've read that a heavily discharged or defective battery can cause this. Anyone experienced something similar?

Sounds familiar. I had a similar heating issue with my Mini One, though I didn't check the error memory myself. The rear window demister was completely dead, and the windshield heating was acting up too. How old is your battery? I'd start there.

The battery is probably around 5 years old. You mentioned a similar issue was it definitely the battery in your case? And did you also have an error stored?

Yep, pretty sure it was the battery. I didn't check the error codes myself back then, but the symptoms were identical. I was getting weird electrical issues too, like the start/stop system acting flaky. If your battery is that old, I'd say get it checked out by a shop. Could save a lot of headaches.

Just wanted to give an update. You were spot on! Took it to a workshop, and the battery was indeed the culprit. Replaced it, and everything's working perfectly now, rear window heating and all. Cost me 290€ all in. Thanks again for your help!
