The Solution: Dealership Encoding




THE SOLUTION: Dealership Encoding







Starting with DME M1.X systems, BMW implemented an improved method of creating the variations of the control modules known as control module encoding.

Codable control modules contain all available programs for an application. However no specific functions are available until activated through coding.

Advantages to dealership encoding:
- Fewer variants of the same basic control module in parts departments
- Cost of storing control modules is reduced
- Reduced inventory management and order expenditure for the parts department
- Shorter vehicle repair times due to immediate availability
- Lower repair costs

Codable control modules allow the Parts Department to stock fewer control modules while still meeting the demand for an ever widening variety of control modules.
