Astra Rear Window Heating Issue

Afternoon, I'm having trouble with my 2019 Vauxhall Astra diesel. The rear window heating isn't working. I've got an error stored, and the windshield heating seems less effective too. Could a heavily discharged battery be the cause? Mileage is at 191414 km.

I had a similar issue with my Astra, though it was a while back. I'd start by checking the voltage of your battery, especially after it's been sitting overnight. Are you experiencing any other electrical issues, like the headlights dimming or the starter motor struggling?

Thanks for the quick response! No other electrical issues that I've noticed, just the window heating. When you say similar issue, do you mean the rear window heater specifically, or something else?

Yes, specifically the rear window heater. I spent ages trying to diagnose it myself. In the end, it turned out to be related to the battery management system. It might be best to get it checked out at a workshop.

Appreciate the insights. Sounds like I'm best off getting it professionally diagnosed. I took it to a local garage, and as you suggested, the battery was heavily discharged. After replacing the battery and clearing the error codes, the rear window heater is now working. Final repair cost was 290€. Thanks again for your help!
