Application – BMW E81/E87 LCI 116i N43 with Automatic Transmission

The presented ECU DME set with CAS3 module and key is dedicated to the facelifted (LCI) BMW 1 Series, specifically the 116i version with the N43 gasoline engine, paired with an automatic transmission. This complete set ensures consistency between the engine control unit, immobilizer module, and key, significantly simplifying the installation and vehicle startup process after repair.

Combining the DME control unit, CAS3 module, and key in a single package reduces the need for lengthy programming and matching of individual components, which is particularly important when repairing electronics in modern BMW models.

Technical Characteristics of the ECU DME + CAS3 + Key Set

This set belongs to the group of electronic control units and controllers responsible for managing gasoline engine operation and authorizing startup. The DME control unit works in conjunction with the CAS3 module, which handles immobilizer functions and key communication, ensuring proper engine startup.

The set is configured for a gasoline engine and an automatic transmission, which is crucial for the correct operation of the powertrain, gear shifting logic, and engine control strategies. This solution allows for the restoration of full vehicle functionality after a control unit failure or CAS module damage.

Benefits of Using a Complete ECU Set for BMW

Choosing a complete ECU DME + CAS3 + key package offers a range of practical advantages, especially in the context of servicing and diagnosing the BMW 1 Series:

• Consistency of electronic components responsible for startup and engine control,
• Reduced risk of issues with immobilizer and key matching,
• Simplified workflow for workshops when replacing the engine control unit,
• Faster restoration of vehicle operability after an electronic failure.

For professional service centers and independent workshops, this translates to a more predictable repair process, and for the end-user, it means quicker vehicle startup and stable powertrain operation.
