odometer show wrong km number why ?
So I bought a car about 2 months ago, and when a bought the car it has driven
35609 km. So I been driving around with it for almost 2 mounths now, and
about 2 weeks ago I went on vacation so i just parked the car outside in a
week. A few days after I got home I noticed that the odometer now says that
the car has driven 29654 km, so it has been set back ! how is this possible? is
it because it was very cold so it has messed up the odometer ? or how can
this be ? and should i change the odometer ?
