Yes your car is very likely AGM. My 2007 ML is even AGM! However stop-start is a good indicator of an AGM battery. Don't use the regeneration mode on an AGM battery though, even though it will let you.I've just received my CTEK MXS 5.0 from Amazon. It's charging my car battery right now. The instructions are a bit vague - I couldn't decide whether to set it to "normal battery programme" (for use with a wide range of batteries, including "many AGM batteries") or the "AGM option" (for "charging most AGM batteries"). I've assumed I have an AGM battery because I have start/stop and it's too bloomin cold to stand outside fiddling with taking the battery cover off to have a look. I've set the charger to AGM mode and all appears ok for now.
BTW, I haven't noticed whether or not the start/stop is working lately. All my journeys in the last couple of months have been too short to expect it.
I'm not a battery expert but CTEK told me that regenerating an AGM - or using the normal battery programme - once or twice won't damage the battery but you shouldn't do it repeatedly. Using a Lithium battery charger on a normal or AGM battery (and vice-versa) is a definite no-no though, or so CTEK told me.
