The 2001 BMW 318 typically has a timing chain rather than a cam belt. Timing chains generally require less frequent replacement than cam belts, as they are designed to last the lifetime of the engine under normal driving conditions. However, it's always a good idea to check the owner's manual or consult a mechanic for specific maintenance recommendations.
