Hi,

i tried to immo off a 018A ecu from a TT. I did this many times before.
The file looked very clean after read via the me_95040 tool in boot mode.
There is no login and vin in the file.

I changed 12 and 22 to 2 for the immo and calculated checksums with a tool.
After i wrote the file back i checked the adaption channel 91 as always but it wasnt 1, it was 4. huh

So my immo off didnt work. I read out the file again, it is the immo off.... so my write worked.
hmmmm.....
I wrote a older immo off file from 018J but nothing changed. Channel 91 is still 4, not 1. Adaptions and WSC stayed the same. VIN is emptry in vcds.
I tried to change the adaptions and workshopcode with vcds but nothing happened.

I can write it and I can read it but the VCDS screen didnt change

Whats wrong with thi ecu?
