Okay so I'm in a bit of a situation here. My 2014 X5 has been cranking slower for a couple weeks and I know these cars are ridiculously sensitive about battery registration. I don't want to pay the dealer 1500+ for something simple, but I also don't want to fry my alternator by skipping the registration step. Been looking at the Expert BMW Battery Installation Service at Battery Zone UAE and from what I can tell they claim to handle the coding, but has anyone here actually used them and verified that they register it properly? Like did your start stop and voltage behave normally afterward? I'm in Dubai Marina and really don't want to risk someone messing up the IBS sensor or causing parasitic drain issues. Also do they bring an AGM battery or just a standard flooded one? Any BMW owner feedback would be amazing before I pull the trigger. Really don't want to learn this lesson the hard way.
