Generally speaking, computer programming of Mercedes-Benz cars can be carried out. Mercedes-Benz's computer system is usually called electronic control unit (ECU), which is responsible for managing various electronic functions of vehicles, such as engine control, braking system and air conditioning control. Programming operation can be realized by special diagnostic tools, such as Mercedes-Benz's Star diagnostic tool or Xentry diagnostic tool.

Through computer programming, the owner or technician can diagnose, configure and adjust the ECU of Mercedes-Benz. It can help solve some faults, optimize vehicle performance and even upgrade the system.

However, it should be noted that computer programming is not a common operation of ordinary car owners. Usually, only specially trained and certified technicians or authorized maintenance stations can carry out diagnosis and programming. In addition, incorrect programming operation may lead to vehicle problems, so when computer programming is needed, it is recommended to find experienced professionals to operate.

To sum up, the computer system of Mercedes-Benz can be programmed, but it needs to be operated by experienced technicians or maintenance stations to ensure safety and correctness.
