The button in the trunk lfor raising the hood when it is in the trunk to improve access to storage in the trunk doesn't work.
I was told that the pulse sensor needs to be replaced; part number 1385262.
I can't determine its location from any diagram searches.
I tried replacing one that looked the same but that caused new issues so I guessed wrong. Please let me know where that part is located. Thanks

 

I have the same problem and Volvo assistance said to me that the faulted sensor is above the left rear wheel, but I don't advise to change by yourself, there are more than 10 sensors for the roof and can be diagnosed and repaired only through a complex procedure.
