4 x BMW E63 E64 E93 Alarm System Module Sensor DWA Control Unit Set 6950525

4 x BMW E63 E64 E93 Alarm System Module Sensor DWA Control Unit Set is a set of original components from the Electronic control modules and controllers group, designed for the factory BMW alarm system. The set allows for the efficient replacement of several key components at once, which facilitates fault diagnostics, restores proper alarm operation, and maintains the consistency of the vehicle's electronics.

Specifications and technical data

Purpose and function of the set

The presented set includes four electronic components responsible for operating the DWA alarm function in selected BMW 6 Series (E63, E64) and 3 Series (E93) models. The modules and sensors work with the vehicle's electrical system, monitoring signals from body sensors, central locking, and comfort systems, and then transmitting them to the security system. This enables effective vehicle monitoring, siren activation, and integration with factory controls.

Benefits of using original BMW modules

Using original BMW controllers and sensors ensures full compatibility with the vehicle's electrical architecture. This means:

• proper communication with the data bus and other controllers,
• stable operation of the alarm system without unwanted errors in the fault memory,
• preservation of factory comfort and security functions.

The set of four elements facilitates service – in case of alarm problems, the entire set can be replaced, minimizing the risk of leaving a single, unstable module in the installation. This is a practical solution both for workshops specializing in BMW electronics and for users servicing their cars themselves.

Technical characteristics and vehicle integration

As elements from the Electronic control modules and controllers category, the DWA alarm modules are designed to work within the vehicle's controller network, taking into account requirements for interference resistance, power stability, and digital communication. The set is intended for installation in locations provided by the manufacturer, which facilitates service and limits the need for installation modifications.

Before installation, it is recommended to verify compatibility with the specific vehicle equipment version and to perform adaptation or coding using appropriate BMW diagnostic software so that the alarm system is correctly recognized by other controllers.

Condition of components and service application

The set comes from dismantling and is intended for users and services looking for proven, original components for repairing the factory alarm. This type of solution is particularly useful for:

• repairs after flooding or damage to the electrical installation,
• problems with incorrect arming or disarming of the alarm,
• random siren triggering or error messages related to the security system.

Replacing the set of modules and sensors often allows for shortening diagnostic time and reducing the number of trial repairs, which is important from the point of view of service costs.
