To the OP.
My experience with Shimano motors are X3.
My first Shimano was a e7000, I sold the bike to my Fiancée's son with 2500 faultless miles (it's still going strong).
My second & third bikes have e8000 motors.
One came up with e010 code the other week. Turned out to be a battery connection problem & not the motor as it was originally thought. This motor has just over 3500 miles.
My second e8000 has nearly faultless 3000 miles. I had it serviced just the oher week & had new drive bearings fitted as a matter of precaution, because they told me one was a little dry.
I personally cannot fault these motors. I have zero experience of Shimano's CS so I cannot comment.
May I ask where you got your E8000 serviced Monkey Dog?
I also live in Derbyshire so wondered if it was done locally/
