Leaking rear “Citroen” styling trim or the rear boot.

If you need help with your C3 Pluriel, that seems specific to the Pluriel (like the roof), ask here. Engine and Transmission problem must be asked in the relevant topic for the problem. The Pluriel shares the same Engine, Gearbox, Brakes and Transmission as the other C3 models (see above for the correct section).

Questions about the Pluriel Roof system can be asked here
No engine, gearbox or running gear questions
Think: Pluriel roof and rear window jobs
Did you know the Pluriel shares the engines, gearboxes, electrical, audio system, suspension, steering and running gear with the early C3?

If you attach some of your own photos (from your own car) showing where you have identified the point at which it leaks it may be possible for someone to use the link you provided and help with a solution.

The Pluriel can leak from many places. It would be a good idea to identify the source of the leak before proceeding.

Hi C3CAR.

Here's a pic of the right side of the rear boot window:

I put sealant all around the window (arrow number one) but there's still a leak from the right side.
What I am wondering about is whether the leak is coming from the arrows number two or from the big opening with arrow number three.

Thanks.

Hello again.

I changed the duct tape on the openings of the bottom of the trim shown by arrow number one on the following pic, on number 1A we may see an opening without a tape covering it.

Arrow number two covers the nuts (2, 2A etc) where go the trim assembly screws.
I put duct tape on them in order to male a better seal.
In my specific case only the opening of nut 2A is where the water came from.

These openings (one of each side) seem to be drains for the accumulated water that is normally supposed to evacuate through the drains shown by the arrow on the next picture.
Tried to clean that one as it seems not to flow OK.

I can see that the hole looks a bit blocked with dirt, and possibly some corrosion?

Thank you for sharing your pictures and thoughts :)

Hi C3driver52.

No corrosion there as the trim is made of plastic.
That must be dirt but I am sure it does not block the flow of water.
There is black sealant that is visible on the pic.
I cleaned the opening where the arrow is using metal wire.

Another thing I noticed is that after spraying the rear boot window with a power washer for three minutes there was no leakage BUT after I opened the window in order to check for a leakage there was a small one.
I have a feeling that was because I didn't wait for the water to evacuate through the drain openings and forced it to run from the bottom by opening the window.

So next time I will only spray with water under pressure but won't open right away to see if there's going to be a leakage at all.

I went today to the car wash and sprayed the rear boot window for three minutes with water under a lot of pressure.

After 12 minutes there was this much water inside:

AND probably because I opened the upper door to take the picture above there was that much water afterwards:
Leaking rear “Citroen” styling trim or the rear boot water dripping

Next time I'll see how much water there will be if I don't open the door.
Just let the water flow through the drain openings WITHOUT lifting the door and therefore directing it through the openings above that i had shown in my previous posts.

Thinking of it I believe the water accumulates inside the styling trim and evacuates through the drain openings VERY SLOWLY no matter how hard is the rain falling.

The amount of accumulated water is time dependent and not flow dependent.
