Hello I think about getting one of the two diagnostic devices listed. Does anyone have experience ? I just want to work with the SL. Can the CR max do everything the MB3 can….or more? Does the MB3 go deeper and better into the diagnosis only for Mercedes? The CR Max can probably be a complete diagnosis and then displays all the ECUs. The errors are then marked red. With the MB3 you must probably look into every ECU whether there are errors, or? Please for experiences and advice. Thank you
