Problem:
It is a 2021 BMW X1 2.8i engine with B46D DME.
Can’t read Isn with Yanhua Acdp with B48 adapter, no matter what option I try.
Keep getting an entering safe mode error.
What could be wrong or this DME is not supported? (I’ve done many of these usually.)


After 2020/06 the DME is locked.
ACDP cannot read ISN for the locked DME.
