RCZ Diesel Power Loss

My 2013 Peugeot RCZ diesel is giving me grief. Engine's lost power, feels like a slug, and the computer throws an error code. Anyone seen this before? Mileage is at 215223 km. Could it be the engine control?

I had something similar with my RCZ, also diesel, some time ago. Was it a main relay issue perhaps?

A main relay? Hmmm, interesting. What were your symptoms, exactly? And what did you do to fix it?

Pretty much what you described: reduced power, error code... I went to a mechanic, and yep, the problem was caused by the main relay. He replaced the ECU, and it solved the issue.

Cheers! That's super helpful! Went to the workshop, they swapped the main relay - cost me about 120€ - and now she's purring like a kitten again!
