well.... i switched off the ignition twice on the way home, still didnt work. But after leaving it over night, I turned it on just now and its all come back to life
So its working again...... no need to reject this one just yet
oh and yes, its a 3 week old 16MY.
The only thing i did differently to normal, is i tried to switch the TC off before i started the engine and moved off, as i had a curb to jump. obviously that didn't work and froze the whole thing... I suppose given the tech, you have to treat it like a computer. switch it off and switch it back on again
