C&D Pillar

Hi looking for some help. I have been getting a lot of water coming into the passenger side foot well & having looked at this post went to check the pollen filter & front sunroof drainage pipes both of which were ok after I tested with the hose. What I did discover was that the leak was coming from the pillar just behind the 2nd row of seats of the left (someone mentioned C or D pillar but not sure what they are called. Water only appears to be coming in there but does the fixed middle & rear sunroofs have their own drainage pipes or when I removed the panel is the one I could see the rear drainage from the front sunroof?

Any guidance would be appreciated.

That would be the C post. Only the opening sunroof has any drains, so it the rear front roof drain. They are same type as fronts. May have perished or pipe come adrift.

Given the age of your car, unless the fronts have been done by a previous owner at best you are on borrowed time before they perish.

C pillar

Thanks for the response. Agree given age of car its a matter of time. As I never open the sunroof & don't want water inside the car could I just use black sealant on the sunroof ?

Hi all,

Thanks for all the wealth of knowledge here, just getting through it has taken a while but very worthwhile.

So, here's my issue.

I've had water coming in from passenger side, have put sealant there for now and whilst it's not properly fixed it will do for now.

My biggest issues is water in the drivers footwell. I followed Gareth's post (very helpful) re drainage pipe, disconnected them, poured water directly into them and it is not blocked. Water ran near front wheel where it should. I then connected the pipe back up and poured water in the sunroof section you mentioned and water misses the pipe completely and comes directly in through the roof. Seems as though there should be a plug or sealant in the sunroof to stop water being able to escape so freely.

Having done all this the drivers footwell seems to still be very wet, I'm not sure it is coming from the sunroof now but don't know where it can be coming from. It feels as though it is from under the carpet. Would the best thing be to pull the drivers carpet back and check out?

Is this nasty to do, always worried when I pull things apart that they won't go back properly.

Any help is welcomed, pictures always a bonus too.


Cheers
Dan

Any tips on getting the rear connecters seated properly when reinstalling the CJB? I just spent a few hours trying to get them connected. My neighbors will probably be hiding their children as I'm sure they learned a few new words today.

I just can't seem to get the rear connectors to seat properly.

Thanks.

Iced up Sunroof drains

After reading the 15 pages of great advice and experience, I decided to tackle my intermittent leaky roof.

As I have the D4, fortunately the passenger side has the dummy air intake grille, so both front pipe outlets are easily accessible Smile

Dealer looked to have been there before me as there was no X shaped valve on either side, and the foam insert was trimmed/butchered.

Armed with a small bore silicone rubber tube fed into a sports drink bottle with one of those 'cat's bum' type valves, I proceeded to blast some water down the drain pipes.

Nothing came out of the drivers side, so I tried the others, including the rear drains which both drained great. I then tackled the blocked Drivers one from the outlet end, and to my surprise, loads of Ice came out ! after which I blasted hot water from the top for a few time and all clear !

It then dawned on me that the intermittent problem only happened in winter after a cold night that turned into a rainy morning, when I started the car for the first time. A few inches of the exit pipe must freeze up and even if the top end is liquid, it takes time for the lower end to thaw. I hear the water sloshing around and get drips down the A pillars/Map reading lights, after a while it stops, even if it carries on raining.

What happened to LR testing in cold climates ? or maybe its just the British Freeze/Thaw cycle in winter.

Happy I now know Smile
