Most BMW cars in Europe, even 90%, have an outdated software version in the controllers.
What does it mean? During the production of a car, the manufacturer uploads to it the most up-to-date software for all drivers.
In today’s vehicles, there are from 20 to even 50 controllers that manage the whole car. Modules/controllers are simply microcomputers with their own flash memory, i.e. data that control components of the whole vehicle, such as engine, gearbox, air conditioning, electrical voltage, suspension, traction control (abs, esp, VDM), airbags (passive safety), navigation and entertainment, etc.
When our car has outdated software, its operation is not optimal and significantly accelerates the wear and tear of components of the whole vehicle and directly affects the comfort of travelling.
Very often the update solves problems such as:
- Lack of flexibility in the work of the bruise while driving
- High combustion
- Sticking EGR valve
- Cogged particulate filter
- Turbine with low efficiency
- Gearbox does not run smoothly enough
These problems, apart from user errors and physical failures, are very easy to solve just by updating the drivers in the vehicle. In order to eliminate to a minimum the frequently occurring faults, it is absolutely necessary to update the drivers. After such a procedure we have a guarantee that the car has no errors generated by its errors in older versions, which in the long run contribute to failures.
After the update, the power of the drive unit increases very often, because the map of the engine controller (ECU) itself is optimized by the manufacturer, and thanks to that the car simply drives better.
Inexperience, the difference between the factory engine software and the updated one is several hp/Nm.
