now that i have fitted an mx6 speedo reading in mph & mile's it's going to throw the mot station computer when i next get an mot, has anyone got any idea as to what happens in a case like this, do i have to contact DVLA or just tell the mot station / tester when i next take it in for test, cheers, lee.

take the old one with you and explain,

It can't be a problem

The speedometer and odometer do not form part of the MOT test so the tester will not care what it reads.
