Even some Foxwell readers may not be able to read the O2 sensors correctly. Ensure you have a good reader that can read all 4 sensors correctly. You have to display all 4 sensors to see if it is possibly reading them correctly.

In fact I tried the same on our other 2010 XC90 and here the values seem perfectly fine. So I guess the reader works.

Oh nice you verified it. So, either O2 sensors, cats, something else, etc.

What do your spark plugs look like and how is your oil consumption today?
