Peugeot 4008 Fault Code Reduced Power

My 2015 Peugeot 4008 diesel is throwing a fault code and the engine power is seriously reduced. I've got nearly 287529 km on the clock. Feels like it's limping. The error's stored in the error memory. Any ideas? Could this be related to some chip tuning I had done?

Summary of the thread

A 2015 Peugeot 4008 diesel is experiencing reduced engine power and a fault code, possibly linked to aftermarket chip tuning. The issue is likely due to interference with the engine control unit. The recommended solution is to consult a reputable automotive workshop for advanced diagnostics and resolution.

I drive a Peugeot 4008 as well, and I encountered a similar problem not too long ago. My scan tool revealed a diagnostic code indicating an issue with the car computer. It also impacted the engine power. Have you scanned the car for any diagnostic codes? That would be the first step.

Yeah, I scanned it, that's how I know there's a fault code stored. But the code itself is kinda vague. What exactly was the error code you got on your 4008?

While I do not recall the exact alphanumeric sequence of the diagnostic code, I can confirm that the technician at the workshop indicated it was most likely due to the third-party chip tuning interfering with the engine control unit. Given that your symptoms and vehicle model align with my prior experience, I would strongly suggest consulting with a reputable automotive workshop equipped with advanced car diagnostic capabilities.

Cheers for the advice! Took it to a shop, and you were spot on. The aftermarket chip tuning was messing things up. Cost me 180€ to get it sorted. Lesson learned!
