VW Passat 1998 1,6 KM adjust

Hi

What do i need to change km on this car?
VAG-Tacho cant do it, and it cant read out the EEprom either with VAG-Tacho.
The Speedo is a Magnetti Marelli MM4 EU according to VAG-Tacho.
I have succesfully read out the login key, and programmed a new key for the car.
The reason for asking, is that one of my friends just got a used speedometer replacement for his car, and he asked me if i could get the km to fit a bit better.
The car has run just over 200.000km, but the speedo has 460101km on the clock.

Best Regards

pretty sure a tacho universal can see attached pdf

Not sure but find out if immobiliser is in instrument cluster, mileage might be the least of your worries after swap the car may not run

Do you know if it can be done with the VAG-Tacho cable?
