XC70 Incorrect Vehicle Coding Error

I had something similar happen on my XC70. The engine light came on too. It was a weird situation. I'm no expert, but have you tried using a scan tool to read the fault code? That might give you a better idea of what's going on.

Thanks for the quick reply. I did use my scanner and got the fault code. Was your fault code also about a coding problem, or something else? Any details would help.

Yes, the fault code I got pointed to a coding issue as well. If I remember correctly, it's best to have the control module checked out by a workshop. It is a tricky thing to fix.

Just to let you know, I took the XC70 to my mechanic. It was incorrect vehicle coding, like we thought. Cost 360€. Thanks for sharing your experiences; your advice helped a lot.
