For some reason, i cant get the two screens to even display any digits. All iv done is read the data. Digiprog read 0 and so did smelecom, so i soldered back on and now i have this problem. Dash lights and fuel guage work but its just the screens. As far as im aware only the dash km is needed to be changed. Has anyone got a good file as i think mine has corrupt just from reading the data for some strange reason. Iv loaded a 89k file which i found on here but no joy. Worst case is second hand dash. Car starts without dash so i assume no coding needed. But is there any ezs coding needed? Will mileage display properly and not ———— like some mercedes when you change dash. Thanks in advance
