A small evap leak in a 2001 Volvo S80 is typically caused by issues within the evaporative emission control system. Common culprits include a loose or damaged gas cap, cracked or broken vacuum hoses, or a malfunctioning fuel tank pressure sensor. Additionally, a faulty charcoal canister or leaks in the EVAP system components can also contribute to this problem. It's important to perform a thorough inspection to identify the specific source of the leak.
