These vehicles need to be driven until the engine computer can perform a check of the entire emissions system (called a "Drive Cycle"). Some cars can achieve this in a short time, other take much longer. I suggest you take this to a Volvo shop, they will be able to perform this test drive in a much more efficient manner than you can.
