I have a Mercedes A-Class CVT with error codes 0722/0793—what should I do? My A-Class CVT transmission isn’t working—can you repair the ECU? Can you remove my Mercedes A-Class ECU for repair?
The most common issue with the W169 Mercedes A-Class CVT (Continuously Variable Transmission) is a loss of the engine speed signal to the gearbox ECU. This often results in error codes 0722 and 0793 (RPM Signal Lost).
What Can Be Done?
In these cases, the ECU needs to be removed and sent for testing and repair. While we do not carry out the repair itself, we can remove and refit the ECU once it has been returned.
•Since we cannot engage third-party repair services on your behalf, the component would be handed to you to arrange shipment for testing.
•Repairs typically take 5-10 days, and your vehicle will be off the road during this time.
• We can offer guidance on where to send the ECU for repair.
