My ekpm3 module in the trunk, has gone off the sh*ts lol and keeps overheating i guess.. & I just actually replaced the fuel pump itself and all its connectors/housing etc… but ekpm3 module still spazzing and prob even dead at this point tbh.. so I need to take my ekp2 module I have from a 535 e60 that’s actually two years older than my 535.. I flashed the “ZBE” and thought I even programmed it all right.. but inpa or any other app, seems to still say that it’s an ekp3 module when I run any scans etc. So I clearly skipped a step or did sum wrong a litre advice or help, to point me in the right direction would be greatly appreciated
