Great tutorial. The airbag error probably was caused because after you fitted your new aux battery you have turned ignition on the check if the error message dissappeared but you had the seat airgbag disconnected. Did the same procedure on my w166 to replace parking sensor module and when testing new part plugged in the airbag wire and had no errors appearing.
