impa 5.0.6 E84 file missing

[x1newby]

Hi all
i have just installed impa 5.0.6 in the quest to check and make sure battery is registered properly on the wifes x1 2012 ,as it has always said battery drain and shuts off radio when ignition is on ,and gets the car on ramp ,anyhow the battery looks new from when we got the car and i believe they changed it before selling and probably not registered ,anyway back to the missing ability to use the E84 option on impa can anyone tell me if this version will work if i can obtain the file ,many thanks.
