Hi guys,

i despair with my r270.

I want to change vin and odometer from an e90 kombi, i open the dashboard, desolder the 080D0WQ-EEPROM and put it in IC-Socket from my R270.

Then i will start R270 software 1.20, "select mcu" -> "080D0WQ" -> "OK" -> "Read" sometimes it comes an read error, sometimes it reads with 1/1024, sometimes with 300/1024 but not more...

I think i bought the good edition from r270, black plastic case?
An 0L01Y from my CAS3 there can read and write without problems.


Already tried;
Put external 5V from an USB-Cable to the R270 eeprom board (see picture)
Clean the 080D0WQ with braid (in german Entlötlitze)
Feels like 1000 times put eeprom out of IC-socket, restart r270 and so one...

I would appreciate about any help !
