Seat Tarraco Hybrid Anti Theft Alarm Problem

My 2023 Seat Tarraco hybrid has an anti-theft alarm malfunction. The error is stored in the error memory, and the alarm system isn't working. I suspect it might be the alarm system coded to activate optical locking (indicators). Has anyone seen this before?

Summary of the thread

A 2023 Seat Tarraco hybrid experienced a malfunction with its anti-theft alarm, which was stored as an error in the system. The issue was suspected to be related to the alarm system being coded to activate optical locking. The problem was resolved by recoding the system at a workshop, which fixed the malfunction.

Hmm, that's odd. I had something similar happen with my Seat Ateca. I thought it was a battery issue at first because the security alarm kept going off randomly. Did you check the alarm sensor connections? Maybe it's a loose wire somewhere, or perhaps the immobilizer is acting up? Not sure though, just throwing out ideas.

Alarm sensor connections, you say? Where exactly are those located? And did your Ateca throw any error codes, or was it just the alarm going crazy?

Mine didn't show any specific error codes, just weird alarm behavior. As for the sensor connections, I'm no expert, but I think there are some under the hood and maybe near the doors. Honestly, it might be best to take it to a workshop. They can diagnose it properly. I ended up doing that, and it saved me a headache.

Turns out the anti-theft system was coded to activate optical locking, which caused the issue. Recoding it at the workshop fixed it. Cost me 45€ Thanks for the input.
