Focus Electric power loss ECU fault

I'm having a serious issue with my 2011 Ford Focus Electric. It's got 129123 km on it. I've noticed a significant reduction in engine power. My auto scanner shows a fault code. I'm suspecting it might be related to some chip tuning I had done. Has anyone experienced something similar? Any advice?

I had a similar issue with my Focus, not the electric one but the regular engine model. Same symptoms: power loss and error codes popping up. What codes are you seeing?

I'm pulling code P0606, which seems to point towards the car computer. Did you have the same code? What exactly was the issue in your case?

Yep, P0606 was the one. I'd suggest getting it checked out by a workshop. It's probably beyond a DIY fix, especially if it involves the ECU.

Alright, I appreciate the advice! Took it to the workshop, and you were spot on. Turns out the chip tuning fried something in the ECU. Cost me 180€ to get it sorted. Thanks again for the help!
