Finally i changed my side marker lights.
I made plastic tools to get behind the reflectors and pressed the plastic grips together so the markers came loose.
So no need to take the wheel off and did not have to take the inside wheel cover off.
I saw they were not even connected!
I bought new light bulbs, but was not nessesary.
Could it be that in europe these side marker lights are not allowed?
And that they disconnected them to pass the control?
