SMAX Incorrect Coding Error

I own a 2021 Ford SMAX with a diesel engine and 142465 km. Recently, a fault code has been detected. I am receiving an error stored in the error memory. Furthermore, an error message is displayed within the infotainment system, and another in the speedometer. Could this be linked?

I have an SMAX and experienced something similar! Was the control module light on? My issue turned out to be incorrect coding. The malfunction indicator was driving me nuts! Did you check the engine diagnostics? I was about to lose it!

Yes, the engine light was indeed illuminated. Can you elaborate on the incorrect coding and what steps you took?

Well, I tried resetting the codes myself, but it didn't work. Apparently, some parameters were off after a software installation. I would advise you to take it to a workshop and have them check the control module. It's probably beyond DIY territory, but they'll sort it out quickly.

Thank you for the advice. I took it to a workshop, and it turned out to be an incorrect vehicle coding. The repair cost was 360€. The issue is now resolved.
