Kit Purpose and Configuration

BMW E81 E87 LCI N43 116i 2.0 122HP ECU Control Unit Kit DME CAS3 + Key is a control kit prepared to work with the N43 gasoline engine in the 116i version with 122 HP, for E81 and E87 facelift (LCI) body types. In one package, you receive the DME control unit, the CAS3 module, and a matching key, which maintains the integrity of the security and powertrain control system.

A kit configured this way is particularly useful for:

• replacing a damaged engine control unit after an electrical or mechanical failure,
• post-accident repairs where electronic components have been damaged,
• communication problems between the DME control unit and the CAS3 module.

Benefits of Using a Complete DME + CAS3 + Key Kit

Using a complete control kit for the BMW 1 Series with an N43 engine offers a range of practical service benefits:

• Powertrain Electronics Consistency – the DME control unit, CAS3 module, and key come from a single system, minimizing the need for deep software intervention.
• Simplified Diagnostics – a unified kit simplifies diagnostic work using factory BMW tools, allowing for quicker resolution of immobilizer-related errors.
• Time Savings in the Workshop – a ready-made kit reduces the number of programming and adaptation steps compared to replacing individual modules.
• Economical Repair Option – a used OEM kit allows for restoring vehicle functionality at a lower cost than purchasing new components.

Technical Characteristics and Vehicle Integration

The kit belongs to the Electronic Control Units and Controllers group, meaning it is responsible for key engine management functions and start authorization. The DME control unit works with engine sensors, the ignition system, and the injection system, while the CAS3 module handles key identification and communication with other comfort and security systems.

When selecting a kit, it is worth paying attention to:

• compatibility with the engine type (N43 116i 2.0 122 HP),
• body generation (E81/E87 LCI),
• appropriate software matching for the vehicle's equipment.

The availability of OEM part numbers and interchangeable numbers presented in the technical specifications facilitates compatibility verification by VIN or factory markings.

Condition, Service Application, and Selection of Used Electronics

The product is offered as a used BMW OEM set, making it an attractive solution for workshops specializing in the brand and for informed users seeking reliable electronics at a reasonable price. Used control modules are often chosen for repairs of vehicles several to over a decade old, where a balance between cost and functionality is crucial.
