Power Steering Reservoir for CHF11S Fluid, URO - E30, E36, E46, E34, E39, E60, X3, X5, Z3

This is the complete power steering reservoir with filter and cap for ZF power steering units in many/most BMW models using Pentosin CHF 11S hydraulic fluid.

Why replace this reservoir? There is a filter inside that is not removable. To service the filter requires replacing the reservoir. Also the connections on the bottom of this fluid tank are highly prone to leaks. It's not uncommon for the power steering connections to be over-tightened and can cause leaks. If you are trying to solve power steering leaks (which are highly common on the E36 and E46 3 series, as well as other models which share the same power steering design) then changing this power steering reservoir will be one of your priorities. If you've recently replaced your PS pump or rack that is even more reason to install a fresh reservoir with all new, clean, power steering fluid.

This item includes both the reservoir, filter and cap (BMW part # 32416851332).
