Swooshing sound under car

[Yourownpersonaljesus]

Recently I've been hearing what sounds like water swooshing around under my car. I can really hear it when I pull up. My car is a VW Up. Has anyone else had this before? I can't get booked in at my garage for over a week.

Anyone?

My car collects water in the rear doors and does this occasionally. There are bungs which are supposed to open for it to drain out but sometimes they need opening.
It's not a VW though but might be similar.
Can you try each door and see if you can hear it?

Have a read of this. https://www.upownersclub.co.uk/threads/holding-water-sloshing-sound-at-rear.5583/

Looks like you may have grommets in your sills you can remove. They look the same as on my car. We remove them for water to drain and wash the muck off them before putting them back m
Don't know how easy they are to find on your car though.

Thanks Snozzlemaid I'll take a look.
