im not to sure of that one because when i broke down in the middle of a flood (the water was lapping a few inches up the side skirts), and some people helped me push my car out of the water, there was loads of waer coming out, as one of the ladies explained to me:-
'its pissing water out all over the place'
my car started again though, with the aid of a battery 'boost'
it just had the engine warning light on for 20 miles or so on the way home, and it felt like i was driving without any turbo (no power at all)
