Purpose and function in the powertrain

The presented fuel pump control module is dedicated to the hybrid Range Extender system in the BMW i3 I01, where it is responsible for the electronic control of the pump in the petrol circuit. As an original BMW part, it has been designed to work with the vehicle's factory installation, ensuring proper fuel pressure and stable communication with other control units.

Thanks to its integration with the powertrain management system, the module supports:

• fuel pump operation control depending on load and driving mode,
• proper fuel supply to the combustion unit in the hybrid system,
• communication with the network of controllers responsible for safety and diagnostics.

Benefits of using an original BMW module

Using an original electronic control module in the BMW i3 I01 Hybrid Rex allows for maintaining consistency of operating parameters with the manufacturer's factory settings. This is particularly important in vehicles with hybrid drive, where the petrol system works in conjunction with the electric drive and energy recovery systems.

Key advantages include:

• precise fit to the vehicle's electrical system,
• preservation of the factory fuel pump control logic,
• easier diagnostics within the BMW system,
• consistency with the software of other control units.

Technical and fuel characteristics

The module has been designed to work with a fuel system based on petrol, which is crucial for the proper operation of the combustion unit in the Hybrid Rex version. The control electronics are responsible for regulating the pump's operating parameters depending on operating conditions, which affects engine refinement and power supply stability.

As an item from the Electronic control modules and controllers category, the product integrates with the vehicle's communication bus, enabling the reading of errors and operating parameters during service diagnostics.

Condition, installation, and service application

The offered module is a used part, which is an attractive service solution for users looking for original components at a reasonable price. Replacing the fuel pump controller is recommended in situations where there are problems with starting the combustion unit, unstable operation of the fuel system, or errors related to the fuel pump circuit.

Before installation, it is worth verifying compatibility with the vehicle based on the part number and the configuration of the specific BMW i3 I01 Hybrid Rex unit, and entrusting the installation itself to a workshop with experience in BMW electronics.
