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 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 x300m

Connect X300m to the OBD port on Q5

 

Then, follow to screen

Select the models:

VEHICLES->MILEAGE ADJUSTMENT->AUDI/VW/SKODA/SEAT

 

Select software AUDI/VW/SKODA/SEAT V31.11 for ready use:

Loading software …

Initializing…

Authorizing…

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.
