You should not have mixed the BMW fluid that was left in the trans with the total fluid...the ONLY fluid that is speciifed by BMW is ZF. Period.

Meeting m1375.4 is not a full and adequate spec. In other words, they lied to you about having BMW fluid, then lied to you that the shell spec is adeaute.

You should reset the adaptations. This is what ZF says. I dont trust 'a guy' at a 'zf approved shop'

(WTF is a 'ZF approved' shop anyway????????? Where can we see this listing?)

The 'tech' recommnened a BMW reprogramming?!? lol. What is he even saying?

Basically they said they can do the fluid, then they did a crap job, wrong fluid and didnt reset adaptations...now they are doing (saying) whatver they can to get you out of their life.
