Transmission visit Workshop

[oakin98]

Hi everyone,
Please I need your help. My 2007 B200 suddenly started showing Transmission visit workshop. It has never for once happened to me. I did a scan through my own diagnostic CPU and attached below is what I got from my diagnostic. What's the next thing to do? Is it the ECU that needs reprogramming or what?

Before panicking, get your battery fully charged with a trickle charger. You can do it in situ without removing the battery if its more convenient.

The first fault refers to under voltage, and that could be the cause of the other codes as well.
So fully charge the battery, clear the codes and start the car and see what , if any codes return.

Thanks AMGeed. I bought new batteries yesterday, but still the code 0793 and 0722 was still showing after clearing all codes. What else can I do please?

MB specialist time ? Looks like a gearbox fault as you suspected

+1 unfortunately.

Don't assume new batteries are fully charged, especially if they've been sat around on a shelf for some time. Low battery voltage plays havoc with Mercedes' systems.

Speed sensors failing on the gearbox ecu.

Either repair the ecu, or replace and program, code.
