for those of you who knew sorry to bring this up if you didnt then.........
i have recently taken a 2003 micra with 17110 miles yes 17k and the mot tester accidently put the milage of the last vehicle tested ...39400 miles
i didnt see it till the next day he then corrected the original milage but it stayed ion dvla 's mot check site ..
i emailed dvla who told nme to email motreplacment@dvsa.gov.uk with evidence of milage prior to the orig mot , luckily i had a service the day before at a workshop 4 door up i sent in a pic of the service and a pic of the service book .. they replied @5 days to say the evidence given is sufficientto change the detail.. back to 17110 ... days
just incase you have this issue as we are all only human !
