On-board diagnosis
By identifying the early signs of engine component malfunction, the on-board diagnosis helps to limit any further damage. It also reduces repair costs and makes it easier to identify the cause of the problem.
On-board diagnosis is one of the functions of Digital Motor Electronics (DME), which monitors and manages all core functions of your BMW. The on-board diagnosis system instantly recognises any deviation from normal component function and sends an alert message to the cockpit. You are immediately informed about any issues with the engine, and can take action to ensure that no further damage is caused.
All error messages (e.g. variations in emissions) are logged and can be used at your next BMW Service appointment to find the solution. Instead of needing to search for the problem, your BMW Service professional can immediately start work on eliminating it - saving you time and money.
