Does You use BDM to calc checksum?

If yes use Winols to calculate checksum.

Hi
Yes rigth.
Probably problem with checksum in flash or eeprom.
That year are the cars that you have had the problem?

Mate flash again with the original dump . try the car and after 2 days read again by bdm , and mode the file . Program the ecu with mod file and read again and check the dumps.Maybe in that 2 days maybe someone try to read the file or change it .

checksum was calculated with winols , and no one read the car surely , should i calc it with bdm ?

when you make diagnosis are all of modules instaled on this car reachable?
strange that you are not able to write on obd.
best regards

solution
1.check the errors in ECU,and dash
or
2.use good power adapter and write original file (minimum 12,5v and up and 5a)
