Peugeot 5008 bumper antenna fault

Interesting problem. I had very similar symptoms in my 5008, although I didn't check the error memory. Remote key stopped working, and I had to use the key in the ignition. Did you check the antenna mount? Is it corroded? Is there any physical damage?

Can you tell me where and how you checked the antenna mount for corrosion or damage? Did you have to remove the bumper?

I didn't do any repair myself. I'm not an expert, so I just checked the bumper visually for any damage, and then took it to the workshop. They told me that the bumper antenna and its connector were faulty and had to replace it. So yes, I think they removed the bumper.

Looks like a workshop visit is needed. The repair cost 95€, and the issue was a defective cable connection. Thanks for the help.
