Bricked ECU 540I e39

Postby mapkrk » Thu Feb 22, 2018 3:05 am

Hi guys,

I was trying to chip my e39 540i 2002. I got a file from a German website. I have Galletto 4 and FG Tech for flashing ECU. However when was writing a modified file I got a message that "Checksum is not supported". At that point I didn't now that I shouldn't have kept on writing it on. I messed up and bricked my ECU. I've sent original and modified files for checksum correction and I got corrected file back. I've tried flash the ecu with my new file but I'm getting same error that checksum is not supported. Is there any way I can upload old original file or modified one somehow? Is there any other software which would work with galletto 4 (clone) properly ? Any help would be appreciate ! Thank You !

Get an original BDM read and flash on the bench, BDM/Boot-Mode is the only way now.
Then put the ECU back in the car and flash your new file..

ECU is ME5.2 or ME7.2?(engine 448S1 or 448S2?)

Minis never die.They just get faster
If you speed up on curves instead of slowing down you probably own a MINI Cooper.

DME is ME7.2. VIN GN88085 09/2002

Can I boot mode with ecu on the car ? Is it pin 24 to ground ? I have looked at my fg tech boot mode and I've got a few selection.

Simens-infineo c167 1- bosh me7-1 mirco - flash 400 boot mode
2- bosh me7-1 micro - flash 800 boot mode

I've never done a boot mode before, can please some one guide me through this ?

Also once I'll be sucesfull with boot mode can I flash it with WinKFP to original ?

Thank you for your responds !
