Received OBDSTAR X300M package for a few days and discussed a lot about it on forums. Sounds an interesting topic. Here share something what i did on this obdstar x300M for OBDII unit yesterday.
I used X300M for my Audi Q5 2010 to change km. Very easy; all i did was to follow the screen instruction only.
The km before change: 22850km
And this is the item for mileage adjustment; it‘s OBDSTAR Scanner obdstar x300m
Connect X300m to the OBD port on Q5
Then, follow to screen
Select the models:
Select software AUDI/VW/SKODA/SEAT V31.11 for ready use:
Loading software …
Select AUDI A5 2010
Then go to MILEAGE ADJUSTMENT
The X300M first read the original km (my Q5: 22850km) after communication
Next, to setup the new mileage; i input 105312
X300m change km by itself (about 10-25 min)
The dash also displays the same mileage.
So, it’s successful.
