807 Turn Signal Issue
Summary of the thread
The right turn signal on a 2004 Peugeot 807 diesel was malfunctioning, displaying an error and warning despite the bulb appearing fine. A similar issue was resolved by checking the wiring and plug connection to the light unit, where corrosion was found. The problem was confirmed to be a bad connection, which was fixed at a workshop for 95€.

Thanks for the tip! Where exactly should I be looking for the wiring issue? Any specific spots that are known to be problematic?

For me, it was right at the plug where it connects to the light assembly. The wires were corroded. Honestly, it's fiddly work. Unless you're confident with electrics, I'd say get a workshop to take a look.

Thanks! I took it to the shop; turned out to be a bad connection like you said. Cost me 95€ to fix. Appreciate the help!

Yep, sounds familiar! I had a similar issue on my 807. Have you checked the wiring and the plug connection to the light unit itself? That's where my problem was.
