I have been using autodetect successfully for some time.  My thought is that 
perhaps the forward voltage drop of the diodes is slightly different and this is 
confusing the K2.  You can check this by measuring forward resistance with your 
DVM (some actually measure voltage drop, but if not you want to match the 
measured resistances).  I used a pair of low-drop schottky diodes -- I don't 
know whether this is necesary, but I haven't had this problem.
