Key Differences at a Glance
- D1 Max2: The most advanced model, supporting the widest range of online ECU coding (including BMW, Mini, Porsche, Nissan, Infiniti, Renault) and hidden functions. Also includes Pre & Post Scan.
- D1 ProS2: Similar hardware to Max2, but online coding for BMW/Mini is restricted to Traditional Chinese, and lacks Porsche, Nissan, Infiniti, and Renault coding.
- D1: A mid-range option with a smaller screen, less memory, and no support for BMW/Mini online coding. Supports Audi, VW, and Skoda/Seat coding and hidden functions.
- D1 Lite: The entry-level model. Special Functions and Active Test require a software upgrade (V1.88+). No online coding except for basic brands, and no MaxiVideo support.
Which OTOFIX D1 Should You Buy?
Go for the D1 Max2 if: You need the absolute best. It’s the only model with full, unrestricted online coding for BMW, Mini, Porsche, and Nissan. Essential for specialists.
Choose the D1 ProS2 if: You want high-end hardware but don’t need full BMW/Mini support. A powerful all-rounder if the language restriction isn’t a dealbreaker.
The D1 is for you if: Your work focuses on common brands (VW, Audi, etc.) and you need solid core diagnostics without the premium price tag.
Opt for the D1 Lite if: You’re a beginner or on a tight budget for basic code reading and live data.
Conclusion
The OTOFIX D1 series provides scalable options for every level of automotive repair – from the full-featured D1 Max2 for expert technicians to the affordable D1 Lite for entry-level use. Your choice should depend on the vehicle brands you service most and the level of functionality you need.
