Peugeot 2008 Turn Signal Defect

Interesting. I had a similar issue on my old Renault Megane, a 2016 diesel. I was getting a weird error message and the indicator was flashing erratically. Did you check the bulb housing itself for any signs of corrosion or damage? Sometimes water gets in there and messes things up. Also, have you tried simply wiggling the connector to see if the error goes away? It could be a loose connection.

Thanks. I checked the bulb housing and it looks fine. When you say 'wiggling the connector,' do you mean at the bulb itself, or further up the wiring?

Yes, I meant the connector at the bulb itself. Give it a gentle wiggle while the indicator is on, or trying to be on. If that doesn't work, and given the error messages you're seeing, it might be best to get it checked by a workshop. Sounds like it could be more than just a simple bulb replacement.

I took it to a workshop, and they confirmed a defective connection, as suspected. The repair was 95€.
