Problem:
Failed to read VW Bosch ME17.5 ECM with OBDSTAR DC706. I can only read the VIN number, but I can't connect to read the flash and EPROM. I used a 120-ohm resistor with 14 volts.
Solution:
There are 3 versions of pinouts for this ECU. Use the 3rd pinout.
PIN 87 should preferably be a 12v one, not the ignition that it marks.
Use this pinout.
Both CG CG70 and OBDSTAR P50 will do Audi A6 A8 Q5 hybrid high voltage battery BMS crash reset. Which device is better or faster?
Here is the clue.
CG70 will repair Audi BMS module by CAN Mode.
Part number: 8R0915233, 8R0915591
Processor: D76F0192
Here is an example.
Repair problems: Engine don’t start. Hybrid system is locked.
Select part number 8R0915233 and check wiring diagram.
Connect BMS module with CG70, connect CG70 with main cable and 12v power supply.
Connect with the BMS unit and read the fault code P1609.
The B1609 fault code in an Audi indicates an “Illuminated entry input circuit short to battery”. This means the circuit related to the car’s illuminated entry feature (e.g., door light, interior light) is shorted to the battery, causing a fault.
Click One-click repair.
Repairing BMS in process.
Read module again and you will see that fault P1609 has been erased.
Pros:
Repair by CAN. Easier connection.
Built-in algorithms. Supports one-click BMS Repair.
Cons:
Less BMS part number coverage.
P50 will erase Audi BMS module on bench.
OBDSTAR P50 Audi BMS Support List
| Brand | System | Part No. | Memory | Method | Function |
| AUDI | BMS | 5C6915182A | D76F0192 | BENCH | Check ECU info, read & erase DTC, read EEPROM |
| AUDI | BMS | 5C6915182B | D76F0192 | BENCH | Check ECU info, read & erase DTC, read EEPROM |
| AUDI | BMS | 8R0915233 | D76F0192 | BENCH | Check ECU info, read & erase DTC, read EEPROM, erase crash |
| AUDI | BMS | 8R0915591 | D76F0192 | BENCH | Check ECU info, read & erase DTC, read EEPROM, erase crash |
You need to connect with P004 adapter on bench, read eeprom and erase BMS crash data.
Here is a video guide of P50
Pros:
Support more part numbers than CG70
Cons:
Not one-click repair. Have to read eeprom first.
OBDSTAR released new ECU software V31.90 in May 2025.

How does OBDSTAR X300 Classic G3 display to screen and use it for teaching?
There is an HDMI port on the top of the G3 unit.
What is the purpose of the HDMI port on the OBDSTAR G3?
The HDMI port supports screen casting, allowing you to use it for demonstrations and training sessions.
Connect the device to the HDMI port using an HDMI cable to display the screen.
Mirror the device screen to the computer (or a larger display like a TV) via the HDMI interface.
Possible to cast screen of DC706/P50?
DC706/P50/Odomaster devices don’t have an HDMI port. You cannot make a USB to HMDI converter to work with them.
OBDSTAR OdoMaster and G3 released new odometer correction software in May 2025.

How to reset Mercedes Benz 48V mild hybrid battery BMS using OBDSTAR X300 Classic G3 or P003 programmer?
Tools used:
OBDSTAR X300 Classic G3 or P50 (p50 also requires Bench-A V3 and Bench-B V2 adapter)
Network connection.
If the battery itself is not damaged and the voltage is above 45V, there is no need to disassemble the battery module for resetting.
If the battery voltage is below 45V, disassemble the battery case, disconnect the BMS module, and charge the battery until the voltage reaches 45V–47V. Battery voltage exceeding 48V may cause malfunctions.
Reset BMS Module with OBDSTAR:
Select BMS Reset function- Benz BMS (48V)- ECU Unlock.
Connect T003 adapter battery cable and DCDC cable to the battery module.
Then connect T003 adapter with P004 adapter.
Also connect 12V power supply to the OBDSTAR device.
Unlock BMS successfully.
Go to Test Platform Function-48V BMS- Benz W166 W205 W213 48V battery module.
Hi Start and measure BMS voltage with a multimeter.
It shows the current voltage is 47V. It does not exceed 48V, which indicates the BMS reset is done successfully.
