REM-8F10 Error

[Metallo]

Hi all,

My car is an XC70 AWD 2005 -> without 4C

I get the following two errors in VIDA:

REM-8F10 Position xenon lamp Signal too high
REM-8F13 Position xenon lam Calibration fault

First, I adjusted the two plastic headlamp regulators to a 'middle' position and then I did the Calibration process through the REM module.
The calibration turned green but it did not resolve the problem as the above errors are still there

What are the next steps I should take?
I read the fuses should be checked, which fuse box are they located? Is it the one on the back in the trunk?

Any help is appreciated.

Thank you!
Alex

Has the car been turned off and left lone for a few hours and rechecked? some of the calibrations will continue to show the fault until the car goes into off line mode (goes to sleep). on the next key on cycle the fault codes will be gone.
