See post 80. Unsure, if that answers any of your questions. Your situation is indeed odd.
Strange your OEM BMW charger (CTEK) does not work on your MHT, yet on your non MHT cars. I have an older OEM BMW charger (Deltran) hooked under the open hood to my MHT , no clicking sound, solid green light. Car is new.
Keep us updated, as I am interested in your resolution. I can't find the 48V replacement cost (i will ask parts dept) , some BMW 48v are say $1500.
As a suggestion, try the other forum series, as many others will likely have your same or similar questions. Soon success, I am sure.

My 2012 X1 uses the 2012 OEM BMW trickle charger [deltran) and works fine.
I can also use the CTEK and the Noco 5 with the X1.
The 2021 X4 and the 2021 M340i don’t work with the CTEK. They are both MHT vehicles.
I believe that the X4 works with the Noco5 now..? Not sure, I need to try it again.
The M340i does not accept any of the chargers via under the hood, all of them induce the same behaviour with a small motor noise followed by a clicking noise on the 48V battery area. (Unfortunatley we can not post videos in this forum).
I believe that the small 48V battery is more than $1500 but I might be wrong.
As mentioned above, my shop foreman tried two other brand new 2021 M340i from the dealer’s lot and all behave absolutely identical with sam noise and same click.
They all charge however with the professional BMW shop charger via under the hood. The tech could not explain why this happens. All chargers are BMW oem except the Noco5 which I bought it as I thought it will do the job.
As my situation was desperate I disconnected my M340i trunk battery and charged it with Noco 5 directly with no issues.
Under the hood method however, doesn’t work. As you can read on my previous post, there is a link where other members whee in a same situation with MHT vehicles.
Is just that is annoying and not practical whatsoever.
I am still looking for the proper answer in regards with this.
