If recode will not help, how is it possible to get dump from the dash ?any universal cables or solder ?

Uh, is it very risky to remove arrows ? i will need to push the arrows on the gauge side ?

just follow pic and use solder point or remove pointer and go direct to eep

You may read EEPROM also from rear side without removing pointers. I can't read what is printed on your processor, but you may connect your serial EEPROM reader here, connect RESET pin to ground, power up cluster and read out EEPROM. The layout posted by gogalv is not correct. Your cluster is different. In case you have 25640 serial protocol is SPI, but it could be I2C as well. Check what your processor supports, or post what's printed on it.

Needles are no problem to remove. Just turn anticlockwise and lift/pull at same time. They will come straight off.
Just be careful when refitting not to push needles on to far.

:coffin:
My drawing is correct, that's another modification, but such points. You can not Deconstructing or clip if you remove the arrows.

Sorry, should have used different words: Your picture with pinout is different because of different PCBs. Junction points should also to be found on the other PCB on different location. But to identify I would like to know what is the processor on board.

once read put required dustance in dash and write in eis 1234etc , however this may have a delphi ecu if so then you will have a flashing enigine light on , due to mileage being different in dpf values in ecu, as they changed the dash board slightly same time as they changed from bosch to delphi, either way star or vas5054 will regen it.

ps how are you going to do eis/ezs etc ?? as cas3 programmer wont do these

This car have bosch.

No , EZS is your ignition switch. There is a miles/km store in it.

If i will leave it unchanged , what will it be ?
Is there any possibility to correct it ?

You have to do ezs,

This isn't well thought through

Moddder I thought you needed to modify dump in cluster so it would show the mileage as you removed a tachometer from the vehicle? Or do you also want a mileage correction?
If you want mod of file no need to do ezs but if you want mileage correction then you'll need a 9s12 secure micro reader/programmer rosfar etc
