I had a similar issue with my last XF and it is more than likely not an ABS sensor, but a wheel speed sensor that is going out. It is an easy fix and the part cost me about $75 (if you are a DIYer). The hard part is figuring out which wheel it is, and the ONLY person who has the equipment to read the correct module to tell you is the chrysler dealer (not even benz has the XF module for their STAR DAS system). Hopefully the guys at your dealership are cool, mine charged me $100 for the 5 minutes it took them to plug in the system....
Good luck
the problem is your abs module you have 3 options to fix
1. replace at dealership around $1,900
2. order an new abs module on a mopar web site around $800
3. replace with a used abs module $ 250
I replaced with a used one and it works fine you can buy at a local junk yard or on ebay
