DIY: Z3 Non-M gauge cluster to Z3M S54 Conversion

[JBanzhaf]

JMH083,

Welcome! If I understand what you’re saying, that should work. You need to read the dump from both the internal EEPROM and the coding plug EEPROM from your original cluster. Then write both of those onto your new one. As long as you have successful reads and writes, you’ll have a clone of your original cluster, with mileage and vin transferred.

Thanks,
Joel

Hi Joel

Thanks for your prompt reply, really appreciate.

So I will try, there are two option to copy dump from coding plug and internal eeprom : remove eeprom by hot air gun or to use special plug to get contact with pin
