I do not know if there are any options but thought i would try. I have a 2 1/2 year old AF-S NIKKOR 600mm f/4E FL ED VR that no longer autofocuses . I can manual focus perfectly fine. I have tried different cameras and nothing. Any ideas, or am I going to have to send in?

You could try cleaning the contacts with De-Oxit. If it is the power contacts that are dirty, it might not give an error as the error messages are about communication faults, not a power fault.

I have to say, I have had this problem with a couple of AF-S zooms. It’s bloody off-putting when a well looked after, fairly new lens suddenly decides it’s had enough. It always seems to be the AF motor and, apparently, some of the early AF-S focus motors are already no longer available!
You seem to have tried the usual steps and if the contacts are clean and their springs are operating properly, it’s probably off for a service.
My 50/1.4 did the same yesterday morning, when I was out. Tried changing settings, AF/MF switch, remounting lens, etc. Nothing. In desperation (okay, desperation might be too strong a word!) I took the battery and cards out, put them back in and, hey presto, works perfectly again. No idea what that was all, about but it’s fine now.

Recently, after a macro session with my D610 and 60mm f/2.8D Micro Nikkor, I decided to shoot some portraits using my AF-S 85mm f/1.8G. No AF! I was completely stumped for a couple of minutes... until I remembered that I always shoot macro with both the camera and lens set to manual focus. I know, totally dumb... but it happens.
So my first suggestion would be to go with Occam's Razor and make sure all your switches are set correctly. If they are then Peter's suggestion about cleaning contacts is a good idea. Also, since the 600mm is a fairly heavy lens, you might want to check the lens mount on your camera for looseness.

Good point - check that you haven’t set back button focus too!
