Please forgive me if this has already been discussed in exhaustion. I have tried to search the posts but never really found the complete answer. My 2014 XF Would randomly flash a code so quickly that I could not even see what it was and occasionally my power steering would feel stiff. This happened just a couple times over the past few months but no other real issues. When I got in the other day I had what seems like every possible fault code display when I started the car. Of note the eco start stop had not been working of late so I presumed that may have something to do with it. The car seems to run and drive fine. I had the batteries replaced and the fault codes reset by my mechanic..The eco start / stop is now working normally again. But a day later I had multiple fault codes display again. Everything from gearbox fault to tps fault to edc fault to abs fault...etcetera. Again, The car again seems to be running fine but the check engine light is on. I am not sure what could be causing this. I have reviewed multiple posts that mention fuse boxes, grounding wires, alternator, etc. I just wondered if a definitive fix was ever discovered to this problem? Thanks in advance!
