Megane Siren Communication Fault
Summary of the thread
A 2022 Renault Megane electric vehicle displayed a 'siren communication fault' error, rendering the alarm system inoperative. The issue was suspected to be due to a faulty cable or connector, likely caused by high mileage. After consulting with others who experienced similar problems, it was resolved by addressing a corroded connector, costing 95€.

Nah, everything else seems fine. Just the alarm. Did yours throw the same error code?

Can't say for sure about the exact code, but symptoms were similar. Alarm was dead as a doornail. Honestly, I fiddled with it for an afternoon and then gave up. Took it to a shop and they sorted it pretty quick. Probably best to get it checked out, especially with modern car electronics.

Cheers. Appreciate the insight. I took it in. Turns out it was indeed a corroded connector. 95€ later and all good. Thanks again!

MEGANE

Hmm, sounds familiar. I've got a Megane too, though a bit older. Had some weird alarm issues a while back. Was anything else acting up at the same time? Like central locking or anything?
