Mini Cooper rear window heating malfunction

I am writing to report a problem I have encountered with my 2006 Mini Cooper. The vehicle has approximately 104337 kilometers. The rear window heating is not functioning as expected. I have observed that there is an error stored in the error memory. Furthermore, the windshield heating does not perform as usual. From my initial assessment, it appears that the battery is heavily discharged or defective, which is a likely cause. I wanted to solicit opinions before proceeding with a defroster repair or thermal window replacement. Has anyone experienced similar window demister problems?

A 2006 Mini Cooper owner reported a malfunction with the rear window heating, suspecting a heavily discharged or defective battery as the cause. The issue was confirmed by another individual who experienced a similar problem, attributing it to the car's sensitive electrical system and voltage drops caused by a weak battery. The owner took the vehicle to a workshop, where the battery was identified as the culprit and replaced, resolving the heating issue.

Did this summary help you solve your problem?

I had a similar issue with my Mini Cooper some time ago. The rear window heating was not working, and it turned out that the battery was the cause. The electrical system in these cars can be quite sensitive. Have you checked the battery's voltage? Is it the original battery or has it been replaced?

Thank you for sharing your experience. I appreciate the insight. You mentioned a sensitive electrical system. Could you elaborate on how a discharged or defective battery directly impacts the functionality of the rear window heating specifically? I am trying to understand the underlying mechanism.

Certainly. Think of it like a chain reaction. A weak battery can cause voltage drops, which can then affect various components, including the rear window heating. In my case, after confirming the battery issue, I opted to visit a workshop to avoid further complications. They were able to diagnose the problem quickly and recommend a replacement. I suggest you do the same.

I appreciate the insights you provided. I took the Mini to a workshop, and they confirmed the battery was indeed the culprit, as suspected. The error memory also indicated the same. After replacing it, the rear window heating is now functioning correctly. The total cost amounted to 290€. Thank you again for your assistance.
