What did you flash onto the car afterwards? MHD/BM3? If so, what tool did you use to flash?I used the M-link to bench unlock my early 21 with pre-june 2020 DME.
I wonder if the price will be same for the post june DME license.
I believe I paid around $400 for the M-link, which came with a lifetime license for 1 car.
So if car gets relocked (which it did during a dealership visit years back), got home, and bench unlocked again.
At time, I was told for any additional DME, license would be $180.
