A properly functioning pump allows for the quick removal of dirt from the windshield, which improves visibility and driving comfort. Using an original BMW solution reduces the risk of leaks, performance drops, and electrical compatibility issues.

Construction and fitment for BMW E36 / E39

The component has been designed specifically for the architecture of the washer system in the BMW E36 and E39, taking into account the factory mounting method as well as hydraulic and electrical connections. As a result, installation is close to plug-and-play, without the need for installation modifications or the use of additional adapters. The appropriate shaping of the nozzles and the pump body facilitates the correct routing of fluid lines and minimizes the risk of air entering the system.
