Update: I had some issues after the EDC removal. What that coding did was to update the Vehicle Order (VO) to pretend the car came out of the factory without the EDC option.
A couple of years ago, I needed to replace a part (Fuel Control Pump Unit P/N 16147411596) which required to be coded into the car. My mechanic had a lot of trouble to make this work.
His notes say "Unable to code EKPM3 with standard BMW ISTA+. Found vehicle order has been modified which caused the ISTA+ programming issues. The EKPM3 is now coded successfully (the only way to code this vehicle is E-SYS only)."
He also said any new part that requires coding will have similar issues.
