I swiftly ordered an MHD Super license, and VRSF downpipe to wake her up a bit. upon receiving my MHD Black Adapter i went ahead and tried to Tune my car to stg1. To no avail only a "progressed stopped" message, onto a message that reads that my DME is currently Locked and requires a bench unlock. Okay fine, I know the dealers update the software's sometimes, considering I had purchased my car Certified Pre Owned, I figured they probably had updated it before selling it to me.
I call my local "repeatable" (my first time using them) tuner shop (VAST Performance in Ferndale Michigan) and they say bring her in we should be able to unlock that AND tune it for you. After explaining to them, I just wanted it unlocked and not a tune, the shop rep kept pushing that MHD is trash and to let them tune it.
6 hours goes by and now they are letting me know that they can "Bench Flash" the DME ONLY and cannot unlock the capabilities of "Port Flashing" during the "Bench Unlock" but can flash tune it while on the bench. My question is, has anyone else ran into an issue like this or is this unheard of on the B58 platform cars before 2020? To my understanding if the ECU is unlocked it is unlocked of both "Port tuning" and or "Bench Flashing the ECU" capabilities.
I don't want anyone to think I'm shaming the shop as I know BMW throws new software's out there and has tricks up their sleeves. Please chime in on your DME unlocking experience that was recent. THANK YOU ( ALSO I STILL NEED MY DME UNLCOKED I GUESS PLEASE HELP, AS I TOLD THEM NOT TO TUNE MY CAR) What should I do?

Simonespeed. I also have a 19 g20 330i which i was able to get the dme unlocked at a local shop for $200 and did my own port flash tune at home which works perfectly. might want to check with another shop and get a second opinion.
