Purpose and Function of the DME/CAS Controller

The DME CAS Computer for BMW E87 LCI and E90 116i N43 is responsible for precise control of the gasoline engine's operation, including monitoring the combustion process and cooperating with other electronic vehicle systems. The integrated CAS module plays a key role in start authorization, communicating with the vehicle's electrical system and other controllers on the network.

Combining these functions in one set allows for consistency in the electronics configuration, which is particularly important when replacing components in modern BMW models. This solution minimizes the risk of software conflicts and communication problems on the vehicle's bus.

Benefits of Using an Original BMW Module

Choosing an original module from the Electronic Control Units and Controllers group ensures:

• factory fit to the electrical system and architecture of BMW systems,
• maintenance of engine operating parameters as intended by the manufacturer,
• consistency with other controllers in the vehicle,
• possibility of professional adaptation and coding using dedicated diagnostic tools.

An additional advantage is the presence of dedicated replacement part numbers, which facilitates the selection of the appropriate controller for a specific vehicle configuration, including comparison of hardware and software versions.

Condition, Verification, and Installation

The module is offered as a used OEM part, allowing for a reasonable cost while maintaining factory quality. These types of controllers are often chosen for BMW electronics repairs, as they enable the restoration of full control system functionality without the need to invest in a new unit.

Before installation, it is recommended to:

• verify compatibility by OEM number and reference numbers,
• check compatibility with the specific N43 engine version in E87 LCI / E90 116i models,
• plan for adaptation, coding, or potential immobilizer matching according to BMW service procedures.

Professional installation and configuration allow for full utilization of the controller's potential and reduce the risk of communication errors in the vehicle network.

Selection by OEM Numbers and Technical Support

Due to the wide variety of electronic versions in BMW vehicles, matching the module by part number and replacement part numbers is crucial. Correct selection guarantees proper cooperation with the vehicle's electrical system, sensors, and other controllers.
