Territory Electrical Issues Antenna Suspected

I had a similar, though not identical, antenna issue with my 2012 Opel Astra. Have you checked the antenna connections for corrosion or damage? It might be a simple fix.

I've checked the connections closely and found no obvious corrosion or damage. Can you elaborate on your Opel Astra experience? Were there specific diagnostic codes, and did you need a full antenna replacement or just adjustments?

In my case, a broken wire was inside the antenna base. We found it after close inspection. Given your symptoms and that you've checked the connections, it might be worth having a workshop take a look. It was easier for me to go to professionals than try everything myself.

A professional assessment is warranted. I'll tell the technician to check for cable or plug defects. I will report the outcome. The estimated repair cost is 95€.
