Didn't get a chance to do any more investigating so took it to the CT for a minor fail to get another couple of legal months to sort it.
Kept pressing the button all the way to the test centre just in case, but no joy - nothing at all, right up until parked outside.
Heard a faint beep from somewhere deep inside the test hall but just assumed it was another car. Tester returns 30 minutes later, 'All OK, nice car' and prints out the report...
I didn't dare say anything just in case he'd forgotten to test the horn, but once safely out of earshot the horn is definately working - and has done all the way home!
Thanks everyone for their input, at least I've watched so many videos about the clockspring and the MFU that I could probably do it in my sleep now if I have to
I know that MGs have their idiosyncrasies but this is ridiculous!
Is there not a sound argument for a special Cobber’s guide to Life, The Universe, Motorised things & everything else.
I would create a computer short cut for that without a moment’s hesitation.

That’s interesting their having had problems with their equipment. My chum who does my MOT tests & who had done since the abolition of the man with the red flag, Dave’s kit does a self test against an internal standard & will not allow a test to proceed if there is deviation of more than a few points.
I’m sure most of us, or at least those who brave the test by close observation will be conscious of time gaps in between tests.
I believe these periods are part of the self test & resetting to datum in preparation for the next disappointment.
