Water Trapped

[sarah.h]

Hi there,

for the last month or so, I can hear the sound of water moving around somewhere to the left of the driver side / front passenger doorway / gear stick area. 
I’ve had a mechanic look at it and he didn’t see any problems but it’s bugging the life out of. Has anyone else had this problem? Thank you Sarah x

Usually water collects in the scuttle panel area below the windscreen and accessed from the engine bay.
If you have a sunroof then sometimes the water can travel down into the area you describe where it should drain out but if the drains are blocked then this may be the reason
