BMW E84 23d 6AT, EDC17CP02, Checksum Error.Help!

[Asmir75]

Hello everybody,

I bought X1 E84 Biturbo with 204HP for 2 Months.
I decide to buy Close Kess V2 with newest 2.47 Ksuite.
ID OK, READ no Errors but at the end it shows Checksum Error and Program will start again.

I think the car is already Remaped by preowner but not shure. And i have no original file of this car !
No problem with car.

How can i fix this and at least i would make EGR off.

Thank you very much.

ID and ECU file are attached.
Sorry for my bad english , my native is german :-)

i dont have full file only something about 100KB?

Why become Checksum fault? How can i fix this or its about already remap.
I can Recovery if something goes wrong with my original full file .Right?

I have only Kess V2 no KTAG you mean Tricore Mode to Backup ECU?

You need open ecu and read bootmode... or, better for you and your poket, let a tuner done what you want!
Clone tool and EDC17 + no Knowledge eieiei.
