when i used to be a peugeot tech mate we had quite a few different models with these problems, 206's where the worse in fact we had a recall on them to drill the lower air inlet pipe.
replaced a few 206 and 106 engines due to them hydrolocked and wrecking pistons,lower ends etc.
we used to think it was maybe because the french being french designed the cars to drive on the other side of the road so the puddles wasnt as bad on that side!!
hope you get away with yours pal but if you was at speed and it sucked it up might not be good
