    Question Astra H speedometer error (ıpc) help me

    Good day to everyone.I have a 2012 astra h 1.6 vehicle.I bought an opc speedometer.kilometers high. I went to eepromcu to reduce the mileage of my own vehicle.The eeprom maker deleted some of the information in the eeprom while changing the mileage. the rpm on the speedometer and the needle on the speed section go down directly to the bottom.While reading the eeprom, it could not fully read the device, I guess, most of them see the data as FF.I have to throw its own software on the speedometer to figure it out.How do I reinstall the original software installed on the speedometer?opc speedometer version: 0.502 49/04

      You need a eeprom dump from IPC number 13216707 QF (OPC instrument Cluster) to restore your eeprom.

      to reset the kilometers to 0 change the first 16 positions to 0
      00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

      and
      Position 17: 01
      Position 19: 00
      Example:

      After restore the dump, you should be able to program your kilometers with opcom without problems.

      Carpass is in positions 234 to 237

      The best way to restore the eeprom is to desolder, program and solder the eeprom on the instrument panel.

      If you no desolder the eeprom, you so many troubles to read and write the eeprom.

      No. You can use a gasoline (or find a newer opc instrument cluster(more difficult and expensive)) instrument from 2007-8 (SW7.655, change the leds to white and enable the scan OPC in the eeprom) Be carefuly, some instruments dont work sport button, ParkPilot, ids... Sould be a Sport instrument from a car whit any optional extra, like Parkpilot.

      Its a possible solution.
