Seat Arona Anti Theft System Problem

I'm having some grief with the anti-theft system on my 2019 Seat Arona diesel. Error memory's showing an anti-theft alarm system malfunction, and the alarm system is just not working. I'm guessing it could be a power failure, maybe a battery issue related to the alarm system. Has anyone seen this before?

That's a strange one. I've got a Seat Arona too, and I had some weird electrical issues last year. Was anything else acting up, like the central locking? Or did you notice any other error messages?

Central locking seems fine. No other errors that I've noticed. You mentioned electrical issues. Was it related to the alarm control or anything similar?

Yeah, mine was behaving oddly after a flat battery incident. The alarm system seemed to go haywire after that. I'd suggest taking it to a workshop and get the alarm control checked. Could be a coding issue after a power failure.

It turns out the anti-theft alarm system was coded to activate the optical locking, indicators flashing when locking or unlocking. The error was related to this. I had it recoded and it's sorted now. Cost me 45€. Thanks for your help.
