Laguna Alarm System Error

Interesting. I also drive a Laguna. Did you notice if your indicators were flashing erratically, or staying illuminated when the car was locked or unlocked? Sounds similar to what I experienced. Have you checked the battery's condition recently?

Thanks. No, I haven't seen any erratic indicator behavior. The battery's been checked, and it seems fine. Could you explain the symptoms you had?

The indicators flashing upon locking/unlocking was the main thing. It turned out the alarm system was coded to activate the optical locking confirmation, which was causing the malfunction. Since your symptoms are different, it might be something else. Maybe a faulty alarm sensor? I'd recommend a workshop. They diagnosed and fixed it quickly for me. Good luck!

Thanks for the info. You were right. The alarm system was coded for optical locking, which caused the error. Repair cost was 45€. Thanks again.
