Any suggestions what I should look at to find the cause?
I get that code on my XC70. I was told by the dealer its the evap canister solenoid or the hose that goes to it. Most likely the hose. It gets hard and brittle and cracks. Its a pain to get to on the XC70. About $160 to fix the hose and $400 is its the solenoid. This is a vent system from the gas tank. It routes vapor to the canister. Its all under the car.
I tried changing the gas cap but it did not work. Their is a rubber gasket that breaks on that too. So you can try the cap first.
