I found on internet few different "Diagnosis Tool" for Mercedes Benz but I am not 100% sure if they work efficiently on Mercedes Benz cars.
I lately found on Amazon.com this one: "
Thinkcar Thinscan OBD2 For Mercedes"
It is in this link:

https://www.amazon.com/gp/product/B088YRN5B5/ref=ask_ql_qh_dp_hza

Reading all functions described by the seller it seems to be a great tool.
I would like to know if there are someone familiar with this specific tool.
Thanks
