The system is designed to detect leaks as small a pin hole. BMW and Mini Cooper are equipped with a Leak Detection Pump (DMTL) for this purpose. The most common fault codes for EVAP leaks are a PO442- Small leak detected, and PO455- Large leak detected. The PO455 code is most often caused by a gas cap that was left loose after refueling. The PO442 can be a much harder one to diagnose as it virtually impossible to diagnose visually.
