Many users ignore ASRA, focusing only on WIS diagrams. This is a mistake. The ability to calculate Standard Labor Units allows independent shops to price jobs competitively. For example, ASRA will tell you that replacing a W212 steering rack is 380 labor units (38 minutes). Without ASRA, you might underbid the job by 50%.
When you search for a Mercedes Benz WIS ASRA download new link, ensure the release notes explicitly state "ASRA full database." Many cracked releases omit ASRA because it requires a separate server emulation.
If you find a "new download link" claiming to be WIS/ASRA, run it through these checks:
If you cannot afford the XENTRY Portal and you accept the risks above, there is a safer middle-ground than a random "new link."

Note: If your "new link" does not include a detailed "READ ME" text file with these steps, it is likely a virus.
