Can one device solve all vehicle and function requirements?

No. Automotive diagnostics, key programming, ECU/TCU read/write and tuning file processing are different professional areas. In many cases, several tools are required: Diagnostic tools: fault diagnosis, service reset, coding and programming; Key programming tools: key adding, all keys lost and immobilizer systems; ECU tools: ECU/TCU read/write, cloning and repair; File service software: file processing, such as DPF/EGR/AdBlue-related solutions where legally permitted; Adapters and cables: Bench, Boot or special module connections.
