Hi,

I have an insignia with delco E98 ecu.
Someone Flash the ecu for me with stage 1,egr and adblue out.
But now i have a adblue dtc, it says i have 900km left bevor engine doesnt Start.

I bought a io prog and want to roll back to original Software.
When i read Flash an save it the file size is 4.096kb
My original file that was created from the tuner is 4.128kb

Ioterminal says file size must be 0x400000

What can i do? I read this via obd2.

Thanks in advance.
