well today i figured why this happened, driving along minding my own business in the driving rain and hey the lights went out on the 206, pulled over and waited a few seconds then tried again, all was well. got home lifted bonnet to figure whats going on, errr i forgot to attach the wheel arch liner after i changed the front wing after hitting a deer. ooppps water going everywhere, it was peeing down on my way to Totnes toosuppose that would depend on weather my mrs brings her car to you, had to drive it all the way back from totnes to evesham earlier this week in limp mode with engine light on and showing a pollution fault (155 miles, not including the 30 miles i had to do first in limp to get to totnes to collect the mother in law) , though luckily it cleared up just 10 miles from home, now fine, maybe it didnt want to go down there
now funny that, i did think at the time it was water related.
