Hey everyone, I'm having a few issues reading the ECU in my car. I swapped a VR6 into my Golf, the ECU comes from an '01 Jetta. The immobilizer is defeated, car runs amazing, I'm just trying to code out my engine light for emissions related stuff. I run into some weird problems when I try to read or write flash to the ECU. The same errors come up no matter what I try. I can see that its reporting security access is not supported and from what I've read that has to do with the immo still being on when trying to bench flash but my immo is completely defeated already. Here is the log from my recent session. Hopefully I can be steered in the right direction! Thanks!

As far as I know, yes. I only had someone defeat the immo on it when I bought the ECU.

i can't find it but there is a topic on here about the pin 121 issue
i believe you apply +12v to pin 121 on the bench and read and write all you want
at least thats how it is with my vr ecu (018M)

Ok awesome, I wasn't sure if that applied to my ECU, I assumed it was a ME7.5 issue only.

actually don't take my word for it
i tried it again and it didn't work for me on my me7.1 018M vr ecu
have to search again on how or if the vr me7.1 can be obd bench read. i may have seen something about it only being able to boot mode. but i am not 100% sure
someone who knows exactly may chime in for you
