this is probably a silly question but would the speed sensor on the diff affect the speed on the obc

i dont know, but I have a related questions....
whats the speed on the OBC ment 2 show? cos mine always shows 32km/h

any help?

hi garry. the speed on the obc should read the same as the dash speed. but say i am doing 40 the obc reads around 15 thats why i think my sensor might be knackered. plus if i set my limit to 30 i will be doing around 45 before the gong goes off to tell me i am speeding. have you tried resetting your obc
