You will not need any codes when swapping battery, if I remember correctly all you will have to do is reset the date as it defaults to 2009 and reset the electric windows "one touch operation" easy enough, also the sunroof if you have one. As far as the BMS is concerned reset it if you have a diag. tool, if not apparently they do periodically do a self calibration test so not a real issue, I think I would just make sure the new battery is fully charged before fitting it. I replaced my Lead Acid with a AGM and never changed any setting on the car to say it had been changed to AGM, different rating or anything else, that was three years ago and have never had any battery issues at all.

Forgot to say - thanks Col

Battery arrived today. Jeebus it's heavy, it's going to be double hernia time getting it in there!  2014 BMW 530d Touring, 2006 BMW 650i, 2018 Mini Cooper S

Its always worth getting a second pair of hands on the job to push the cables out of the way and give you space to manoeuvre the new one into place. They are big beasts. Kev
