Many other parts available. Check out our other items!


This Mercedes A Class CVT (Continuously Variable Transmission) ECU is an extremely common problem for the 722.8 transmission.

 

The root cause of this A Class gearbox problem is internal component breakdown of the ECU, commonly causing fault codes including: "0793 - The RPM Signal From Component Y3/9B4 CVT Secondary RPM Sensor Is Not Available" and "0722 - The RPM Sensor From Component Y3/9B5 CVT Output RPM Sensor Is Not Available", among others to be stored in the gearbox ECU. Faults with the output and secondary transmission speed sensor are also very common.

 

When the gearbox ECU fails, the vehicle will experience a loss of power, limp home mode and poor to limited gear selection. A warning message will also be displayed across the dash: Transmission Visit Workshop.
