milage reset
bikecarbfred - 19/5/19 at 11:03 AM

does anyone know how to reset the milage back to zero on a polo 6n 1997 16v
i know the milage relates to the car it self and not engine but ive changed.

suspention, doors, bonnets, wings, brakes, rebuilt engine, alternator, wiring, apart from inside wiring.

and im keeping the car for my self and would be nice to set it to zero, thanks,

Regardless of what you’re changing, it’s still regarded as illegal to reset the clocks against that particular chassis number.

I don't believe it is illegal, but illegal to sell the car on without disclosing the fact.

Yes. I won't be selling it.
Just thought i'd zero it for my self. not for financial gain.

1997 maybe too old, but if not a VW dealer (or suitably equipped person) may be able to plug in a diagnostic type computer and reset it for you (at a cost no doubt).

As above though be careful of the legality of doing this, most certainly if you come to sell the vehicle.

At that era it's reasonably likely to have a 93c46 eeprom on the pcb in the speedo head. If your reasonably handy with a bit of soldering/programming then fitting the chip on a socket and changing the mileage to anything your want isn't so hard.

I am fairly certain the polo 6n's had this arrangement, certainly the mileage was recorded within the dash, (I had to replace a dash, and the new one had 15K greater mileage, never bothered changing the mileage on the replacement dash though)

edit replacement dash, not new

Basically yes. Not all dashs store the mileage in the same format/locations in the eeprom memory as that page shows (some store specific digits separately as pairs of hex values (eg - FC DE is an 8) and not always inverse hex). The last one i did was converting a dash from a mechanical speedo/mileage to a later digital version and i wanted the mileage to match the original so everything was correct.

It's not rocket science to work it out with some lateral thinking.

yup just time consuming
