DMax Chip Tuning Error

I've got a 2023 Chevrolet DMax with a diesel engine that's throwing up some errors. It's done about 156930 km. I'm experiencing reduced engine power and the error memory is showing a fault code. I suspect it might be related to some chip tuning I had done by a third-party provider a while back. Has anyone else encountered similar issues?

A 2023 Chevrolet DMax with a diesel engine is experiencing reduced power and error codes, suspected to be caused by third-party chip tuning. The issue is confirmed by another owner who faced similar problems, attributing them to the chip tuning. The recommended solution is to have the ECU re-flashed to its original settings by a professional, which resolved the problem for both parties.

I had a similar experience with my DMax. Same symptoms: reduced power and a fault code. Are you sure about the chip tuning? It's often the culprit. What code is it throwing?

Thanks for the quick reply! I'm pretty sure it's the chip tuning, yes. The code is pointing towards the ECU, which is why I'm suspicious. What did you end up doing to fix yours?

Yep, sounds very familiar. I also initially suspected the chip. I ended up taking it to a workshop. They confirmed the chip tuning was causing the issue. They re-flashed the ECU to the original settings. Definitely get it checked out by a professional.

Thanks for confirming! I suspected as much. I took it to a trusted mechanic, and it turned out the chip tuning was indeed the issue. They re-flashed the ECU for 180€. Runs like a dream now!
