Hello,

I was wondering if anyone has any advice.

I am working on a 2014 F30 - 320i

It comes with HU_ENTRY L7

The car's idrive was stuck in the BMW boot logo and constantly re-starting.

This would indicate hardware issue.

We got a used replacement unit.

Car originally came with 6NH but was coded to 6NK

Now on this replacement head unit, 6NK won't code on the HU_ENTRY.

log file attachedn

I was able to put it back to original with 6NH, but when trying to code it to 6NK or 6NS it fails the coding process.

Any idea why a used HU_ENTRY have issue coding enhanced BT option?
