Changing a fan belt on an Audi A3 typically takes about 1 to 2 hours, depending on the technician's experience and whether any additional components need to be removed for access. The process involves removing the old belt, inspecting the pulleys and tensioners, and installing the new belt. If complications arise, such as rusted bolts or other repairs, it may take longer. Always consult the vehicle's service manual for specific instructions.
