Thanks for the quick reply! It's completely dead. No false alarms, no siren. Just the error code. Where is the alarm control located in your 407?

Okay, mine was giving false alarms before failing completely. Control unit location can vary, but honestly, I'd get it hooked up to diagnostics at a decent workshop. Could save you a lot of headaches tracing wiring looms.

You were right, took it to the shop. Turns out the alarm system coded to activate optical locking (indicators). 45€ and all sorted. Thanks!

I had a similar issue with my 407. Does it give you false alarms randomly? Or is it just completely dead? Could be a faulty alarm sensor or issues with the alarm control module. Have you checked the immobilizer?
