This error is caused by a faulty lens motor, contaminated transmission, or mechanical damage from dropping. Unfortunately, there is no easy fix for this and it requires service from Canon or other repair facility.

Hey louboyens,
According to the manufacturer error code 18 is a lens error code. What that means is something is obstructing the movement of the lens. I would make sure that your hands or anything else is not preventing the lens from moving correctly when your powering the camera on, and make sure the camera is powered off and not powering on while in your camera bag. Try turning it off and back on and after this the camera still displays the error code you should probably have it looked at by an authorized service technician.

Sincerely,
Allan
