water leaking into boot

[gillall]

2001 passat water collecting in right side next to 12v socket any idea how it gets there???

I had water collecting in the spare wheel well of my 1999 Golf. Tracked it down to a loose connection in the rear window washer fluid tube and a partially blocked washer jet. Smell the stuff in your car, if it smells of whatever you put in your washer bottle, then it could be this.

it could be a small break in the sealant around the edge of the car. open the boot and feel around the edges.

Water leaks are mechanics nightmares!

 

Do as Ralph said and check the smell of the fluid.  If it doesn't smell then it's more likely to be normal rain water.

 

Now, water can enter several ways.  It could enter via the boot seal; rear light seals; metal work seal (where metal is spot welded together, it has sealant to keep water going through - this can be any where, wheel arch, rear quarter, floor boot sill etc.); rear window seal/quarter light seals; the holes where they fitted the tow bar.

 

Remove any carpetting/side panelling and see if you can see any traces of water.  If you're unable to then it's a case of climbing into the boot with a good torch, closing the boot and getting a friend to jetwash the boot area!  It will work!
