What is the reason for the temporary unavailability of the 4matic display in Mercedes-Benz?
2 Answers
Mercedes-Benz displaying the temporary unavailability of 4matic is due to a malfunction in the related system control program, such as issues with the transmission program or the 4ETS system program. However, one of the most notable issues here is the problem with the battery voltage. A damaged battery or low voltage can prevent certain programs from running, and 4matic is one of them. Relevant information about the transmission is as follows: Introduction: A device that changes the speed ratio and direction of motion. It is used to alter the torque, speed, and direction of motion transmitted from the driving shaft to the driven shaft under different working conditions. A gear-driven transmission generally consists of a housing and several gear pairs. Function: During vehicle operation, to adapt to different working conditions, the driving force and speed of the car need to vary within a certain range. However, the existing engine's torque and speed variation range cannot meet this requirement, hence the installation of a transmission.
I've encountered the issue of '4MATIC temporarily unavailable' on my Mercedes several times, mainly due to minor problems with the wheel speed sensors or the electronic control system. Sometimes the sensors get covered with mud or dirt, preventing accurate wheel speed data from being read, which causes the system to automatically enter protection mode. Another common cause is a software glitch in the ABS or transfer case module, requiring an update or reset. This system relies on multiple sensors and controllers in the vehicle, and any unstable signal can trigger an alert. Driving on slippery roads or rough terrain is more likely to activate this issue. It's recommended to visit a professional repair shop as soon as possible. They'll use diagnostic tools to read the fault codes and determine whether it's a dirty sensor or a poor circuit connection. Avoid tampering with it yourself to prevent further damage to components. Safety first!
