18	Lower rear-wheel drive module carefully	When lowering, check for unobstructed movement of electrical lines and hoses in order to avoid causing any damage. For vehicles with code (I01) Air Conditioning Plus, ensure that refrigerant lines (14) are not bent since these must be replaced otherwise. For vehicles with code (I01) Air Conditioning Plus, ensure that the refrigerant lines (14) have unobstructed movement relative to each other and are not damaged due to impacts, chafing, bending or crushing. Ensure that torque strut is correctly introduced into the sleeve.
19	Remove mount on engine and main assembly lifting table with universal main assembly mount		AR01.10-P-2400-06MCU
