Partner bumper antenna electrical issues

Sounds familiar. I had similar symptoms on my Partner. Radio signal was terrible, and the remote key fob became unreliable. Check the antenna base where it connects to the bumper. Water ingress can cause corrosion and disrupt the signal. Also, inspect the wiring harness leading to the antenna; a damaged wire could be the culprit.

Thanks for the tip! When you say antenna base, do you mean where the antenna screws into the bumper, or is there something more to it? And did you eventually manage to fix it yourself, or did you end up taking it to a shop?

Yes, where the antenna screws into the bumper is what I meant. The connector there is exposed to the elements. Honestly, I fiddled with it for a while, cleaned the contacts, but it was a temporary fix. The problem kept coming back, so I eventually took it to a workshop to get it sorted properly. Best to avoid damaging anything. They ran a diagnostic test and confirmed it was a faulty antenna connection.

Okay, thanks a lot for sharing your experience! Sounds like I'm heading for a similar outcome. I'll check the connection point as you suggested, but I think a trip to the shop is probably inevitable. I got a quote for around 95€, so it looks like I will go there.
