I did wonder about the alternator in general when I started doing the tests last year, but testing with the voltmeter seemed to indicate it's OK.
I think the slight hesitation might be a bit of a red herring as I've not got a 100% tight fit between the front pipe and mid section, need to sort that.

It's really odd that clearing the learnt values seems to have stopped it happening again, at least so far. I've made a note of the mileage when I reset it and the date, so I can keep tabs on when it reappears. You'd think that whatever is causing this weird alleged low voltage error (below 8 volts according to one list of fault codes I found), would happen regardless. It's as if once it's re-learnt my driving something is wrong, but with a blank slate starting from defaults it's OK. Maybe it's just trying to tell me it doesn't like my driving style!
