I'm after some advice as to where to look for a leak in my Missus C3.
I've had to rip out the majority of the interior and throw away all the underlay as it's all soaking wet.
I've replaced both front seats but left the rest out to try help the car dry.
I'm also concerned about rust as it's started to bubble. Luckily at the moment it's only surface rust so I will wire brush it all back and spray it all before I replace the interior. I also sprayed all the seams with WD40 to try displace any water.

So...
Passengers side front was soaking from the floor all the way up to the top of the bulkhead. I've not managed to remove the underlay up the bulkhead as it requires removal of the dash.
Drivers side front was soaking on the floor but the bulkhead was totally dry.

Anyone have any idea what may be causing it?
Is there anything common to leak on these? It's a 5 door hatch and not a pluriel.


Any advice welcomed.
Sam.

Not really a common problem with the C3 as it is for the pluriel.

What state is the windscreen lower seal in? There is one that stops water runoff from the windcreen from pouring into the bulkhead area.

The seal below the windscreen has a few gaps in it and isn't tight to the screen. There is however another seal underneath?
My next step was to remove the scuttle all together but I need a puller to remove the wiper blades.

How vital is it that the seal sits tight to the windscreen?

Is there supposed to be gromets on both of the wiper spindles?

Yes, its a tightly fully clipped in one that provides the real water seal.

Its the hidden one that does the work, but if the one you can see is not flush with the windscreen, the one under it may not be clipped in properly.

Are you sure? Have you tried lifting the arm to the up position and after removing the nut, just pull of the wiper arm from the shaft by hand (mine were easy to pull off without much effort at all).

Sealing of the wiper spindles is provided by some custom rubber parts 8 and 9 in the diagram below.

8 is missing.
I can't see that causing the amount of water that's ended up in the car though!
I think I'll have to strip the scuttle off and see what the seal underneath is like.

Does citreon have a service box like Peugeot where you can see all the part prices?

Hello i hope you find the full cause to the leak you have got. When my wife bought her c3 the drivers foot well was like a lake and the reason for this was the wiring grommet going out of the cabin through the a pillar exiting behind the front wing the wiring grommet wasn't pushed into the hole allowing road water to enter the cabin also the wheel arch liner was missing. hope this gives something else to cross off your list.

yes there is a website you can use to find out prices but id advise trying to keep as much as possible the four foot well sound panels are £33.46 for my wifes car and the carpet is £208.30.
the website is https://service.citroen.com/pages/index.jsp you will need to sign up with a valid email etc.

Hi Bailes1992

Do you have a sunroof? Blocked or disconnected drains is a problem in many cars.

I would recommend taking off the plastic covers over the plenum as you plan to do. Any blocked drain holes can soon allow water to build up where it shouldn't.
If at first you don't succeed, destroy all the evidence and pretend you never tried :lol:
