SGO or other ori file does not matter. Please read a little bit more about MED9.1. It´s all in this and other boards. You can use any other file with same number just copy 6C00-6CFF, you didnt recognize that while your tests? Which range is you tool flashing via OBD? Maybe not full flash?

Obviously you're not working with an original file.

For the 1K0907115L_0030 file you're talking about the read protection is located at 0xA59A0  Stock value will be [00 01 11 70] this comes from the read seed/key algorithm is key = seed + 0x11170, read protect will change that to anything else.

But another file will make the map i have for this sw ver not fit the ecu anymore right? So if i update the ecu now the program i just wrote by bdm doesn’t necessarily fit the new se version?

But you are right that solution would have been perfect from the start!

Immo data is no problem those I know how to change in the Ecu.

I’ve been reading quiet a few posts about med9.1 but unlike the ME7.1.1 there is not total write up so all the data is hidden in threads with other subject. So any reference is appreciated!

I would say you are probably right! I working with an Ecu purchased from German Ebay so most likely it is not standard or have been altered somehow.

However it doesn’t make my problem not exist. I think Lars was the helpful person that fixed the issue I just need testing now. So let’s see how this file works out.
