Opel mileage correction,Opcom or Digiprog 3?

How to  change km via OBD for Opel cars?

Here is the Carl Barte use use Opcom firmware v1.45 change opel cars mileage feedbcak 


opcom-fw-1.45-change-mileage (1) opcom-fw-1.45-change-mileage (2) opcom-fw-1.45-change-mileage (3) opcom-fw-1.45-change-mileage (4) opcom-fw-1.45-change-mileage (5) opcom-fw-1.45-change-mileage (6) opcom-fw-1.45-change-mileage (7) opcom-fw-1.45-change-mileage (8) opcom-fw-1.45-change-mileage (9) opcom-fw-1.45-change-mileage (10) opcom-fw-1.45-change-mileage (12) opcom-fw-1.45-change-mileage (13)

I just posted what Carl Barter did with his Opcom.

But i think it’s better to not try to modify km with op com because i try in a Agila and dash shows 000000, and i remove dashboard for repair.

Someone told me that Agila has nec processor,not possible diag with opscom but some mileage machines can do it. Probably!

But to change km to Opel, i prefer Digiprog 3 now. I did it on most Opel cars, almost without issues.
