Most probably locked. Every ECU ive had after 6/10/2020 could not be unlocked.
My ecu date is 6/6/2020. I need to have it checked out some day and see if it is able to be unlocked. It's so close to the 10th of June that it may be able to narrow down the dates for tuners even further.

I can use bimmer code on mine with out any issue 6/26/20 is my date. I've turned off fake sound, auto start/stop a bunch of other stuff the warning sounds etc. Does it mean I can be tuned ?

Per what Visconti states, any ECU dated 6/1/2020 and after is unable to get tuned. I believe P2tuned stated the same thing when I listed my ECU date of 6/26/2020 . At this point we are sitting ducks unless you go with a JB4

Damn it lol all good. Then why are people stating they can't use bimmer code. I've had 0 issues using mine.

It's not all Bimmer Code, it's anything in the Body Domain Controller. You can access and make changes, but when it attempts to code them you get an error code.

What in the bdc do you usually change in it with bimmer code? The only reason why is because these guys say they can't do anything. While I haven't run into any issues is all im saying.

The two I was planning to change in there was always starting in Sport mode, and changing the angle of the passenger mirror in reverse.

I changed mine no problem and currently have my mirror set to 30 degrees and starts in sport mode with no errors for the flash when I did it

Are you sure your ecu is after 6/10/20? Everyone I have heard from has this issues with the BDC. Interesting
