When I look at my PC screen I can see a reply by me which gives an easy way to know more about your problem but you haven't mentioned it at all. Can you see it?
Sorry i didn't mean to leave you out. I actually don't have any other lenses or know anyone else who owns an slr. :(. I'm getting ready to go to the shop right now.
I have had an error like that when my aperture lock disengages. Pull the battery for 30-40 minutes (after all the electricity disperses away), clean contacts and that is all you can do. That may fix it.
If that doesn't work you may have to send it in. I had this happen to an old D80 and had to send it in to have something done. Nikon wouldn't say much except that it had to be taken apart and have the electricity discharged manually. When asked they told me the buffer reference is for when it is working correctly and is a generic code when it is stuck. Manuals don't always help fix items.
Yeah, i looked in the manual, but didn't find any info on the matter at the time.
The AF failed again yesterday night and hasn't come back, unlike last time. I have a feeling that something has happened in the af motor in the body. I was shooting an event so used af quite a lot and noticed a slight change as the week progressed.
I do have one one suspicion that my 50mm 1.8 never actually clicks in once its mounted properly. Do all lenses click? Its fully locked in though, i cant screw it any tighter and im definitely mounting it the right way.
