Bought a X5 M50i. Corporate owned before me and for some reason they broke the valve flap connector on both exhausts. Odd but ok. Anyway when I come to flash it it fails at 2%. I have tried chaeging and everything fails.

What year and have the DME's been bench unlocked?

It’s a 2020 built 12/19 but seems that my 3 recent updates just locked me out of doing any tuning for now.

You should still be able to pull the DME's and send them off to get bench unlocked. There are tons of places that do it ... Kies, Cedars, etc. The other much easier and comparable alternative is a piggyback like JB4 or Racechip.

I am told only one vendor can unlock and it takes days / weeks to send to Finland to unlock.

That's true for 2021 model year and newer. Your 2020 should be fine based on the build date. From Kies website:

NOTE 1: If you vehicle has had any software updates recently, it is possible that BMW could have locked your DME, which would require bench unlocking to install a BootMod3 tune.
NOTE 2: If your DME has a production date after 6/2020, then you will not be able to have your DME unlocked for tuning. The only way to view your DME's production date is to find the label printed on your DME, not by checking the production date of your vehicle chassis.


If you have a post 06/2020 build date on the DME, then it has to go to Finland.

The last time i ran into this it meant that your DME was locked. Kies can do this for you and have it back to you the next day.
