I am in the middle of this search too, and need a scanner that can do ABS. I just bought the Innova 3160 because it specifically says on their website to work on the Crossfire. It does NOT work for ABS or any enhanced codes, and I am returning it.

Do any of these Actron work for ABS on your Crossfire? On their website they say the CP9580A does not work for ABS or enhanced for the Crossfire.

Amazon has an icarsoft brand specifically for Mercedez I'm thinking of trying. Also there is an Autel A619 that looks promising.

In the past I tried BlueDriver for iOS and it does not work for enhanced codes on Crossfire. (Adding this in for future documentation).
