Peugeot 206 ECU Relay Issue

My 2014 Peugeot 206 diesel is acting up. Reduced engine power and a stored error code. Diagnostics say it's a defective engine control unit, maybe the main relay. Anyone seen this? It's done 283800 km.

Ugh, sounds familiar. I had similar issues with my Peugeot 206. Is it constantly in limp mode?

Yeah, pretty much stuck in limp mode. Did you sort it yourself, or did you take it to a shop?

Honestly, I messed around with it for a bit, but eventually took it in. A workshop is probably the best bet.

It was exactly that – main relay in the ECU. Cost 120€ to fix. Thanks for confirming my suspicions!
