Hi to all.
I need a help to program a replacement ECU for my 99 Mercedes CLK320. Mercedes part # A0245455932, Bosch part # 0261204918. Inside I found two chips that I think are EEPROMs. Both made by TI. One is B57678 and the other B57943. I think the first one is the immobilizer chip. I just couldn't find any data that would allow me to read and program the EEPROM. To recode the replacement ECU I used Carsoft software but I guess that didn't copy the immobilizer info. So now, after installing the replacement ECU my original problem with throttle not working is fixed but the starter doesn't want to crank. I do not have the STAR or access to it except maybe towing the car to a Mercedes dealer and paying for it. I appreciate your help.
