The code library is limited to generic OBD2 (P-codes) plus some manufacturer-specific codes up to ~2013. It will not help you with U-codes (network) on modern cars.
Score: 6.5/10
Autodata 45 Free (v3.45) is a brilliant piece of software for its era, but it is not a modern solution. If you own a 2005 Honda Civic or a 2012 VW Golf and you need torque specs and belt diagrams without paying $50 for a manual, this is fantastic – provided you can install it safely without infecting your PC.
However, if you work on anything newer than 2015, or you value your cybersecurity, avoid it. Modern alternatives like ALLDATAdiy ($20/month), eManualOnline ($30 one-time for a specific car), or even YouTube (ChrisFix, ScannerDanner) are safer, legal, and more accurate.
Final advice: Use the free cracked version only as a nostalgic tool on a disposable, offline laptop. For real work in 2026, pay for a legitimate service. Your computer (and your customer’s car) will thank you.

If your budget is zero, use these:
Autodata has a cheaper version specifically for non-professionals. It offers repair times, scheduled maintenance, and technical specs for a fraction of the professional price. No crack needed.

If a new technical service bulletin (TSB) is released or a wiring diagram changes, you will be working with incorrect information. That leads to misdiagnosis, angry customers, and re-dos.
