I have heard about the same problems in other 700's. The bis culprit was due to water getting into the unit via the vent line and freezing. Another problem I have heard of is contaminates in the CV boot area.
Out of all the complaints I have heard when someone thinks the EPS is acting up it has ended up being an issue with the CV boot / joint.Bandit said:My EPS light has never came on. And being i ripped a boot a rode the rest of the day, i think that might be my problem.
