What can I do

Answer
They probably can check the instruments panel communication, with the body electrical control module which stores the true value.
Or they can check the BECM (see prev.) functionality, and the instrument pack functionality.
Or maybe the faul cased by the miles-kilometres changing.
(the BECM stores market and locale specific datas which can be reprogrammed)

I't all what I can tell you.
