Could the vehicle's KM be reversed? Help

Friends, hello everyone. I am Mert, I am 25 years old living in Istanbul. I myself own the Astra J 1.4T vehicle. A few days ago we bought a second hand 2006 model 1.4 diesel 206 for a very close friend. The vehicle's interior and exterior condition was in good condition. When the friend went to see the vehicle, the ones who came before him came with his own masters and did not show the vehicle to the master by relying on their control knowledge. But when I got behind the wheel to try the car, I saw such a situation on the km indicator. As you can see in the video, at first, it seems to be 160.000 km, then when it makes half contact, it goes to 500.000 odd and then it gets back to its former form as you can see in the video. What is it? What is this, does anyone have any information?

Thanks in advance, guys.

Now, my teacher, that is the km that comes out at first, you press the button on the indicator and it continues until I press the button again. If I aim to see the km done, I use it like this during the day or weekly. Obviously, I couldn't make a point of forgetting to reset the km counter and drop the km of the vehicle.

Sir, the first km should be the normal km, the last one should be the daily km, but there is an inconsistency here, obviously played. Under normal conditions, daily km reset itself at 1000 km. But there is an inconsistency here

[QUOTE = KILIÇ] Sir, the first mileage should be the remaining oil change, the last daily mileage should be, but there is a discrepancy here, obviously played obviously. Under normal conditions, daily km reset itself at 1000 km. However, there is an inconsistency here [/ QUOTE]

As if they made the dropping wrong, the vehicle is likely to give maintenance warning to 548,000 km, 10 thousand km afterwards. stand on the subject, thoroughly investigate before going back to the selling person, learn the exact truth of this event, if necessary go to the authority of the opel.

The km remaining is the normal km after the first maintenance.

70 thousand km per year has not done so much, you have to look at the worn condition of the vehicle.

I think it looks like they haven't assigned the software that is likely to be played km :)

Stay away from this vehicle, I think.

Friends, this data corresponds to 70,000 km per year. Obviously, this is not possible for me, that is 70,000 km of roads per year. There may also be a mistake in the indicator, but I still could not unravel it.

engine oil level. Didn't you make an inquiry

In the query we made from tramer, km information did not come. The friend who came before with his master came to trust him.

The oil level is in the form of oooooo, which shows the fullness. ooo___ also means _ the amount of fat deficiency. But I think the km has been reduced.

[QUOTE = pusutr] oil level is oooooo already, which shows fullness. ooo___ also means _ the amount of fat deficiency. But I think the km has been reduced.

The first mileage is the distance left, but it should not be like that !! It counts down from 20000 and burns steadily ... the second level of oil .. 3. the normal km information. you have to press the button on the screen for daily mileage ...

How do I reset the maintenance km of friends?

If my friend has been dropped, they say go ask about it.
