Software updates
The operation of mechanisms in modern cars depends on the serviceability of electronics, so updating Mercedes-Benz software is an essential part of car maintenance. This service is only performed at modern car centres with special computer equipment. To check the current status of the software and find out if there is a new version available, the system must be connected to the car manufacturer’s server.
When software updates are necessary
Regular software updates are necessary for the correct operation of Mercedes-Benz electronic control units. Programming specialists are constantly updating programmes and fixing bugs. Therefore, each new version works more efficiently.
Malfunctions may occur in the Mercedes-Benz electronic control unit software itself. An update allows you to fix the problem, and the mechanism will work correctly again. The need for this procedure can be determined by the results of electronic system diagnostics.
Which control units require software updates
Mercedes-Benz cars with modern equipment are fitted with electronic control units. These are necessary to monitor the operation of mechanisms and record errors that occur during operation. For the stable operation of the entire car, it is necessary to update the ECU programs for:
- The engine;
- The gearbox;
- Climate control system;
- Fuel pump;
- Headlights;
- Steering rack;
- Fuse box;
- Brake system;
- Parking sensors;
- Other mechanisms.
When servicing Mercedes-Benz electronic equipment, it is possible to change the operating parameters of various systems. Locked functions are also unlocked, new navigation maps are loaded, and audible signals are disabled or enabled. Specialists can adjust system modes, such as the Start/Stop function.
Software update stages
To update Mercedes-Benz software, a service centre technician connects the vehicle to a diagnostic system. The computer checks for new software versions. If there are errors that need to be fixed and improved programmes are available, they are installed.
This process can take less than an hour, but sometimes it takes several hours to fully diagnose and fix errors in Mercedes-Benz electronic control units. The duration depends on how different the new version is from the old one and how many control units need to be updated. The technician may recommend updating related mechanisms, such as the engine and gearbox, to ensure their stable operation.
Advantages of servicing at our workshop
Mercedes-Benz cars are equipped with complex and expensive electronic systems that require the latest software versions to function properly. A full and correct update of the control units can only be carried out at our workshop with original computer equipment and tools. The technicians are highly qualified, so the service is performed as quickly as possible and without the errors that may be made by employees of non-certified service centres.
