<p>Thought I would add my 2c just in case somebody stumbles across this old thread in the future...<br>
I recently had an issue with my old Canon 400D no longer Auto-focusing with any lens. I first got err99's immediately after I had trouble removing my nifty fifty (jammed on, used force to remove it cracking the crappy plastic mount). After a while the errors stopped, so did the AF...<br>
In my case it was the very left pin in the body lens mount (AF pin) had jammed down (possibly slightly bent from using force to remove the 50?)<br>
What I did was apply a little Isopropyl Alcohol with a cotton tip and worked it up with a sewing needle carefully. After it came up enough to grab it with tweezers I applied more alcohol and worked it carefully up and down until it was springy like the two next to it.<br>
Have not had an issue since, but am also not using that 50 anymore either...</p>
