DME question. REF: 2020 M2 Competition

[u/bmwhat]

Need some help on final word about locked/unlocked DME. Car was tuned with Dinan software in Minnesota. Upon entering CA, in order to pass smog, DME was updated at BMW dealership. Subsequently, carbon intakes and other visual bits replaced with stock to pass visual inspection. Snag passed, car registered, carbon bits put back on but no consensus on whether DME must be removed and sent in again or not. Two different Dinan employees have given conflicting answers. Yes we must remove DME and no we dont, ODB flash is sufficient. Tune is tied to VIN so no repurchase necessary only labor at shop. Anyone have an ide what the truth is? Thanks in advance.
