upto now he isnt sure what the problem is but he suspects it may be a abs sensor on one of the wheels, hopefully it will be a nice easy fix as i dont want to take it to dealership to be ripped off. i will post results when i find out what was wrong with it.
i have a 2004 coupe, manual, rhd
Welcome aboard. Batteries can cause all sorts of issues, but...
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
