At the beginning, I was hesitant to buy Launch X431 CRP909 or Autel MK808, I heard someone feedback that Autel MK808 only touch screen, CRP909 comes with touch screen and button which will be more convenient to use. By chance, I borrowed a friend’s CRP909 and used one time, I was very happy with it for what it did, then I decided to buy one X431 CRP909, now I used several times and love it, highly recommend it.
BMW E90 for example, I share my experience with Launch X431 CRP909, I will mention the aspects that I particularly like.
- Cover vehicles from 1996 to 2020 yearand like the “AutoDetect”.
Tap “Diagnose”, then “AutoDetect”, I will have vehicle information, I really like this icon when I am lazy.
If you are not sure if your model is covered or not, you can check on the official site: http://qcar.x431.com/crp/index.html#/
- Display live data in text, graph & analog for easy data
Tap “Read Live Data (Mode $01), slide down to view data, then tap “Select All”.
Tap “Record data”.
- I love X431 CRP909mainly because it can access to all control systems to diagnose.

- I thumb up for the “Code search” option which allows me to check DTC online
After reading out the fault code, tap “Code search”, the screen will indirect you to the google to search the code meaning and how to do next.
- Share the “diagnostic Report”.
After reading out the diagnostic codes, tap “Report”, then “Share” to the Launch Company to solve directly.
- 15 special functions
It’s the trend to have special functions as a diagnostic tablet. X431 CRP909 is no exception, I counted it has 15 special functions for choose.
Such as: Oil Reset Service, Electronic Parking Brake Reset, Steering Angle Calibration, ABS Bleeding, TPMS (Tire Pressure Monitor System) Reset, Gear Learning, IMMO Service, Injector Coding, Battery Maintenance System, Diesel Particulate Filter (DPF) Regeneration, Electronic Throttle Position Reset, Gearbox Matching, AFS (Adaptive Front-lighting System) Reset, Sunroof Initialization and Suspension Calibration.
Conclusion:
The X431 CRP909 produced by Launch really is of ingenuity quality, not only meets the main needs of the repairman (full system diagnosis and special functions), but also handles the details in a very user-friendly way, including a clear screen, responsive buttons, auto detect VIN, online check DTC, online transmission of diagnostic reports, etc.
