I changed both front and rear window regulators sometimes ago. I bought new BMW parts and found that there is only a little bit of grease on the pulley and wire.
Definitely the pulley or related parts failed after losing lubrication. Therefore, my two cents is to lubricate well on your new pulley and drive system with grease before installation.
