I have finally replaced my rear light unit on my 2017 v90.

I have experienced an intermittent fault for the past 2 winters leading to the left hand side rear marker lights not working.
The unit I replaced is the long light unit (not the tailgate lights).
This involves sliding the rear bumper out and removing the interior trim.

There are two youtube videos which show this, search for:

'How to remove a 2018 v90 back bumper' and

'How to replace Volvo XC60 Taillight, 2018 and newer'

The process for the XC60 is pretty much the same except for the little plastic cover on top of the bumper. There is also 3 nuts holding the light unit , one at the top and one at the bottom behind the interior panels and one exterior nut behind the bumper.
I only unfastened one side of the bumper which allowed enough space to remove the nut holding the unit.

My unit was suffering from water ingress. I have since discovered on removing the old light unit that the top nut was missing!
