Worked fine for about two weeks after purchase

Then began to work erratically (one day fine, next couple of days no focusing at all, then fine, etc...) for some months
Now does not work at all, must focus manually all the time.
Cleaning contacts: no effect

Used on a K20D body, the body has recently been sent to Pentax (for other reasons), and checked, so no problem from the body
All my other lenses work perfectly fine.
