Purpose and Function of the Water Drain

The presented water drain has been specifically designed for BMW E90, E91, E92, and E93 body types, located on the right side of the vehicle. Its purpose is to control water drainage from a selected body area, helping to limit moisture accumulation around sheet metal parts, electrical installations, and seals. A properly functioning drain supports maintaining watertightness and improves the long-term durability of adjacent components.

Construction, Color, and Fitment

The part is made in a black color, which facilitates aesthetic integration with factory covers and plastics in the vehicle's compartment. The neutral color promotes discreet installation while allowing for quick identification of the drain during service inspections. The construction is adapted for the right side of the body, ensuring proper water flow according to the factory drainage channel layout.

The drain belongs to the Other category, meaning it is a specialized body part, precisely fitted to the specific BMW E9x platform. Using an original solution allows for compliance with factory geometry and mounting points, which simplifies installation and minimizes the risk of leaks.

Product Characteristics and Service Application

The right-side water drain is applicable for both standard replacement of worn parts and for repairs after collisions, bodywork interventions, or clearing blockages in drainage channels. In practice, this is particularly important in vehicles operated in urban conditions, where dirt, leaves, and mud can gradually restrict the flow in factory drains.

The main benefits of using this part include:

• maintaining the correct water flow direction on the right side of the body,
• reducing the risk of localized corrosion spots in adjacent areas,
• better protection of electrical components and connectors located nearby,
• preserving the factory layout of drainage channels in E90–E93 models.

Condition, Origin, and Technical Aspects

The offered water drain is a used part, originating from original BMW production. Thanks to this, it retains factory fitment to the body and compatibility with the E9x series construction. A used component offers a cost-effective solution for users seeking parts with proven mounting geometry while maintaining reasonable repair costs.

It is worth noting:

• dedicated placement on the right side of the vehicle,
• compatibility with the BMW E90, E91, E92, E93 platform,
• black color that aids in aesthetic installation.
