Akshually, a bent damper rod may not compromise the function of the unit unless the bend is so severe that it affects the piston rod seal. The flip side is, you may not be able to find a proper replacement damper fluid. BMW has not been particularly forthcoming with viscosity specs (surprise!). If you do get a viscosity rating, know that there are several viscosity rating systems in use and they are neither equivalent nor easily inter-translateable.
