Another Detect Protocol failed post
So I have an E92 ECM I bought off ebay that is supposed to be an 2018-2019 model. Sticker on the back is gone so I cannot verify.
Trying to read it with my bench harness but is getting Detect Protocol failed. I have two more E92's in my shop (2014 and 2017) and both reads fine on the same harness.
MVPI1 if it matters.
ECU will not connect to a generic OBD2 reader either.
Is it possible that the ECU is somehow broken internally so I am getting this message? I have read both 2018 and 2019 ECU's before with the same interface.
Thanks for any insight.
