Mileage reading Correction!

Thank you for the help nitros :-)

I was told 10 days, but may be wrong by the 7 day reply! Is this correct?

If the link refers to the correct part of the current Guide, see section B4 documentation 

www.motinfo.gov.uk/htdocs/tgs0h000104.htm

The current Guide says a replacement can only be issued up to 7 days for mileage corrections

Taken from the testing guide section " H"

Documentation :

A replacement can only be issued at the issuing VTS for a change in vehicle colour or a change to the current odometer reading. The odometer reading can only be changed within seven calendar days of the test completion, the new reading must be that seen on the day the replacement is issued. If other changes are required, then the local VOSA Office should be contacted. E.g. Local VOSA Offices issue replacement test certificates when the original AE is no longer authorised. Local VOSA Offices can also issue duplicate certificates.

Calender days include Saturdays and Sundays
