411 sprinter with tacho

[Techhead]

Hi,

I'm doing a mileage correction on a 2003 merc sprinter with a tacho, will i need to adjust the tacho as well as the instrument cluster?

I have gone in the back of the cluster and the chip is a 93c66wp, does this store the mileage? on my digi II i can not see this chip.

Thanks for any help.

Car type: Mercedes Sprinter VDO - 93c66 - 2000-2001 years
The mileage is stored in the next lines:
0000: F1 34 F1 34 F1 34 F1 34 F1 34 F1 34 F1 34
0010: F1 34 F1 34 F1 34 F1 34 F1 34 F1 34 F1 34
where the next bytes:
F1 34 - is a mileage

Is the 93c66wp the same as the 93c66?

I tried with the 93c66 setting on my digi II and no read possible.

Yes your right it is a VDO.

By a tacho i mean it has a kenzile tacho chart writer that also displays the mileage.

Just remembered i didn't join the chrysal terminals, could this be the reason do you think?
