I had my 2018 LCI get its software updated this past March (I'm not sure of the istep version other than it was the most current the dealership had access to at that time) and my DME wasn't locked (I'm currently going through tuning with ECUTEK and there were no issues).

ECUTEK? Yes, it's done via OBD. As for the dealer, OBD as well, and they charged me for 2 hours labour!

Have a '17 pre-LCI also so I'm wondering why you need to update to the latest ISTEP?

Exactly. If it's not broken, don't try and fix it.

My '17 runs perfectly well on whatever software it came with.

I no longer have warranty due to the age of the car but still have free servicing up until December when it will be five years old. I happily told the service advisor I am running BM3 and not to touch any software on the car. They still do the oil and other mechanical services but no "updates".

His response..."awesome, how do you like it?"

The new istep includes better steering and diff calibrations. Thats why a lot of owners like to update to the new istep. Theres a whole thread dedicated to this exact topic.

I have a very old istep mine m2 is one of the first and i read of many improvements in dsc eps steering erc and furthermore i have some issue in nbt navigation.
as i have laptop ready to flash it i think is better to put all the car to latest istep here attached the step proposed to Dme, is several step forward looking to numbers, same for Dsc and others modules

I didn’t notice much difference in steering when I had the dealer update mine, but the difference in traction control behavior alone was worth it. Prior to the update the car was quick to pull power even in Sport+, now it allows for much more wheelspin.

I felt the on center feel of the car was a tad better but yes most of the difference i also felt on the dsc behavior. Made the car much more fun!

Is that the same version referenced in first post?

Correct

You can update individual modules and leave the DME on the original update level, without risking locking up OBD flashing.

Hi,

So what are the results?

Does F020-21-03-545 i-step DME Update lock DME?

[Notaligned2]

If I understood this thread correctly if I'm buying a used M2 and the dealership applied an update for the previous owner it could be encrypted like the modern ones and unable to be tuned?

I want to have the option of tuning for this dreaded issue https://f87.bimmerpost.com/forums/sh....php?t=1699999

To get a manual transmission I will have to travel to Germany and import one. If I'm there with limited resources and barely knowing the language how could I determine this. Can you possibly get the version from the iDrive, and compare against some known list?

Any update?
