There are different ways to calculate the covered distance by your car, but car manufacturers don't give this information.
To estimate the distance displayed on your app, we use a calculation which can be a little bit different from the car manufacturers ones.
So, it's not surprising finding a tiny difference between the information from your app, and the one from your dashboard.
That's why you can update the mileage in your app.
Why do I need to update regularly my mileage?
The maintenance work is based on the mileage indicated by your car. Updating frequently this mileage helps us deliver the best maintenance advice.
