I recently sold my 2007 XC90 and had done the LED tail light swap upgrade. I ordered the full LED replacement kit that included the resistors which I attempted to install but still had issues with the Position Bulb warning light. I got used to clearing the warning light...
I have a weird, but not serious problem on my S80.
My car's tail lights are always on when the car is on, no matter what headlight setting I am using. (0, I, II)
I went to the local junkyard to test another headlight switch module, but same problem.
Was wondering if anyone else...
