I think all the control pressure issues caught them by surprise, the problems weren't in all the machines and they seemed to be a little different in each machine that did give problems. Some of the updates increase capacity and some are for poor engineering or oversite. Your issues with your dealer are going to be hard to overcome, the 8010 shares very few parts and problems with the other combines( other than the 7010) that CIH sells. CIH relies on dealer mechanic repair schools to teach dealers how to trouble shoot and repair. They do have phone support for dealers but trying to figure out a problem and solution on the telephone isn't easy.
