Repeated minor fuel evaporation leak code occurred (P0442) & failed to be corrected with sealing gas cap with plastic bag, thus making a hose leak the likely culprit. The next most frequent source of this code is a fractured and leaking charcoal canister "J" tube. Because of a weak design by Volvo, the tube cracks due to aging/heat, vertical vibration, and lack of any support bracket near where it is crimped to the canister. The canister and tube are viewable by removing back driver's side wheel. Look for an approximate 5/8 inch black rubber hose about 12 inches inside the conical black rubber bumper, and tucked directly up under floor pan. From directly below, you can look up and see and feel longitudinal cracks that form just distal to the metal clamp. Mine was cracked on top and bottom, and makes sense because of the up and down vibration with road bumps.
Rather than drop the exhaust pipe/muffler and then heat shield to expose the canister, I simply smeared silicone sealer into the cracks and around the tube. Then, I placed two zip ties around the tube at the crack locations and tightened sufficient to close the cracks but not deform the hose.
After resetting the trouble code, I have had no more P0442 alerts, and saved a sizable dealer bill fixing this common problem.
