Skoda Superb Hybrid Keyless Entry Problem

I've got a bit of a head-scratcher with my 2020 Skoda Superb hybrid. I'm getting an error stored, and the keyless entry is acting up, locking and unlocking is all over the place. To top it off, I can't even start the thing without sticking the key in the ignition anymore. From what I've gathered, it might be related to the bumper antenna, maybe a bad connection somewhere with the car radio? Thinking it's something to do with the vehicle antenna or the antenna mount. Any ideas?

Sounds like a similar issue I had with my BMW a while back. Same symptoms: keyless entry acting up and the car radio was basically dead. Did you check the diversity antenna amplifier? It's often the culprit when you have problems with the vehicle antenna.

Diversity antenna amplifier? Where exactly is that usually located? And how would I test it?

Yeah, that's the one. On the BMW, it was in the C-pillar, but on your Superb, it's probably near the rear bumper, since you suspect the bumper antenna. Testing it requires a multimeter and some wiring diagrams, honestly, it's probably best left to a workshop unless you're comfortable with that sort of thing. Just tell them you suspect the diversity antenna amplifier or a break in the FM antenna wiring. It sounds very familiar.

Thanks for the confirmation. I had it checked out. Turns out it was indeed a defective cable/plug connection to the bumper antenna. 95€ later and everything is working as it should.
