Hi Andy.
Any brake squeel ... even minor ?
I get Amigoes sometimes, and it's usually brake squeel driven ... all clears on a re-start, just like yours, but may not come back for months, weeks, or may come back later same day 
Generally, if I check for faults with the Nanocom, there's none ... what's wrong with that ! ? 
Occaisionally there will be a fault, as you have described ... "intermittant" ... clear it and all is good.
Just to add insult to the confussion, in the 2 yrs I've owned the D2, the "intermittant" fault has progressivley moved from the front left hand wheel, to the front right hand wheel, to the back right hand wheel ....

I'm over worrying about it as a genuine problem ... it's a bug in the software/logic/system that drives the SLABS ECU ... in the music business, we call that an "undocumented Feature" 
Brake squeel !! .... or, the only other thing I have read online that's a distinct possibility is a break of the copper conductor inside its insulation. The two ends of the break generally make a connection, but vibrations can make the contacting ends rub, sending a dirty/intermittant signal to the SLABS ECU.
... and that's all I've got.
Kev..
