BMW Z3 2001 km adjustment

[JohnMarston]

The cluster is a VDO HW 0.3 SW 10


I want to try to adjust the mileage, and I understand it needs to be adjusted in the coding plug (93c46) and internal EEPROM (93S56) to be able to work.
On this cluster I've successfully changed the 93c46 with my CH341A, but I'm trying to do the internal EEPROM which is a 93S56 but when I try to find the mileage (should be 395.333), I can't find it. I can find it when I read the 93c46.

I've desoldered and read the 93S56 with UPA and attached the dump.

Where do I go from here? How can I find the mileage in the dump?

Hello Friend
too nice friend you are testing with a rather particular car on 93S56
You will never find the current mileage
Program plug code 93S56
Save the Bed File
5) Upload the saved file again
Note the Programmed Mileage Example i (km15012)
Now you can take the internal CIP 93C46
5) Programming It With The Mileage Bed (km15012)
If the programmed value has a difference of 16 km
I would have mistaken about the dash
I'll tell you that the dash you have in your hands is 41 weeks from the year 1999

Hi,

Thanks for your reply!
You're indeed right, the dash is from a similar car with the same hw and sw number. I assumed the procedure would be the same for the same clusters (both 93C46 and 93S56).
What do you mean with
"after the value you have displayed you will have to type it exactly on the
93s56 if not the value has a change of 16 kms"
I have powered on the dash and I know the km is 395.333, I just don't know where to find and change the value in the 93S56 dump.

[JohnMarston]

Willing to pay for a solution. I can't get it working.

[perukeyservice]

you real ml is 379343?

[JohnMarston]

No, it reads 395.333 when powered on.

[JohnMarston]

Attached are both the 93c46 and the 93s56. Does anyone know the algorithm to calculate a desired mileage for the 93s56? The 93c46 I can get with Tachosoft.
