jagwit Posted December 28, 2010 Share Posted December 28, 2010 I'm trying to find out where these drain pipes end? There are many threads on the topic of leaking sunroofs but the info I look for seems to be elusive. My plan is to run wires up the pipes to make sure they are not blocked before stripping out the roof lining to get to the sunroof drains.

oldsscool Posted December 28, 2010 Share Posted December 28, 2010 I think youd do more damage then good tbh , if youve got leaky roofs then the drain tubes are quite likely already broken , if not theyre ever so fragile at the point they join the roof tray - just whip your headlining out its not so bad a job , did mine a few months ago and dry ever since INSTRUCTIONS Quote Link to comment Share on other sites More sharing options...
bear Posted December 28, 2010 Share Posted December 28, 2010 Good idea Jagwit. I'm following this post for replies. I wonder if you can blow them through with an airline from a compressor without unseating anything? Regards Quote Link to comment Share on other sites More sharing options...
jagwit Posted December 28, 2010 Author Share Posted December 28, 2010 Another forum has reported cleaning the drain pipes with compressed air but still did not tell me where those drain pipes terminate, so I'm still hoping that someone will share this with us in great detail.

jagwit Posted December 28, 2010 Author Share Posted December 28, 2010 I still want to know where those pipes terminate please? I'm on holiday at present and can not do the full roof lining thing now. Thats why I'm hoping for a quick fix. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted December 28, 2010 Share Posted December 28, 2010 I don't know for sure, but *MOST* vehicles have 4 drains, and they run down the A pillar, and either the B or C pillar down to the wheel well, to drip down onto the ground. I think if you looked hard enough you would find them TBH, in fact, a google seems to give quite a few pictures on D2 sunroof fixes. Quote Link to comment Share on other sites More sharing options...

I found the rear ends when i had bulb failures in my rear upper lights, taking out the light unit reveals the pipes, one of which emptied directly over an electrical connector (way to go LR ) The front ones emtpy at the bottom of the a pillar although i havent found the ends, the pipes are viewable if you remove the A pillar covers internally. Do what i did, cover the sunroofs in vaseline and around the joint with the car roof and wait until the waether is good enough to take the roff liner out Quote Link to comment Share on other sites More sharing options...
teabag Posted December 30, 2010 Share Posted December 30, 2010 Deal with the cause of the sunroof leaks and you won't need the drain tubes. Unless you open the sunroof when there's water on it so as it tilts the water runs off and into the drains each side, helped by the black plastic moulding stuck on the leading edge of the glass, that's why they are only drains at the front corners and not all four. Front tubes drop are in the (A) pillar but don't exit, the pillar has a hole at the base to allow water to drain, the rear tubes exit can be seen behind the rear mudflap/valance just look up to see the tube end.

Are you saying that when the sunroofs are closed, the drain pipes should not be needed at all? IE, that no water should find its way past the rubber seals when closed?

LR issued a fix sheet to change the glass seal to a redesigned one on the early D1s but only if customers complained about water ingress. If your sunroof is leaking and the the vehicle is facing up hill drains at the front won't work very well Quote Link to comment Share on other sites More sharing options...

I looked at the seals and could not see how water could get past them but I thought that there might be something I did not see or understand. This then also leads me to conclude that the water on my cars carpets could not be coming from the sunroofs - too much water, and also no signs of water coming from above the roof lining. Will have to take another look ant the AC drains... Quote Link to comment Share on other sites More sharing options...

Will have to take another look ant the AC drains... There is a seal between the sunroof and the vehicles body that can fail but that will require the removal of the sunroof to reseal, removal will distroy the thin seal anyway. The only leak I have had was when water was coming through a welded seam on the inside of the (A) post. I had to remove the front passengers kick panel to see it with a bright torch and I could see a drip, only one a minute but that's all that's required, it was just where a bracket is bolted to hold the lower dash support rail (4 bolts to remove) so there may have been some stress on the metal at that point, anyway a dab of body sealent over the seam fix the leak but it took nearly a week to fully dry the soundproofing underlay.

dooroy Posted December 31, 2010 Share Posted December 31, 2010 I have a 2001 Td5 and both sunroofs leaked - but intermittently . Having read a lot of posts I reckoned the headlining had to come out for a proper look/fix . When I removed the headlining I found all 4 drain tubes in perfect condition and the the boxes to which they are attached also well sealed to the frame . Blew through them and they were all clear .( A good few posters had said that the drain tubes rarely get blocked - and as pointed out they don't help if car is facing uphill as they exit from the front corners ). So I removed both sunroof frames and found the 'gasket' between each frame and roof to be paper thin and obviously not doing much sealing . I put a good bead of Tiger Seal under each frame and refitted them . Not a drop has come in since ( did the job last June ). It would appear that most leaks are caused by the seal between sunroof frame and vehicle roof failing . You could run a bead of sealant all around each roof if you didn't want to remove them ; or you could try sealing around them with tape and see if it helps . The drains cause problems mostly it seems when either (a) the part they are attached to breaks off or (b) when the box they are attached to detaches from the frame .

teabag Posted January 1, 2011 Share Posted January 1, 2011 This is what the underside of a sunroof looks like for those of us that were unsure Quote Link to comment Share on other sites More sharing options...

bear Posted January 4, 2011 Share Posted January 4, 2011 Hi Jagwit, For my information (and I'm sure for others too) where do they come out? and how did you clear them? Regards Quote Link to comment Share on other sites More sharing options...
dooroy Posted January 4, 2011 Share Posted January 4, 2011 As far as I remember they come down one each side of the gearbox . From underneath you will see 2 rubber pipes coming down one either side of the gearbox. The ends are plugged with a simple type of valve - which can become blocked . The ' valve ' will pull out easily - you may get a dash of water following which can go up your sleeve etc . Just clean off the valve and replace - takes longer to describe than to do Quote Link to comment Share on other sites More sharing options...
jagwit Posted January 4, 2011 Author Share Posted January 4, 2011 As far as I remember they come down one each side of the gearbox . Yep, about where the engine meets the 'box. But they are high up on the transmission tunnel and they dont stick out far either, so dont look for any kind of pipe. They are more of a protrusion than a pipe.

IanS Posted January 5, 2011 Share Posted January 5, 2011 I just took the valves off mine after the carpets kept getting soaked on holiday. I did fit a pipe to the N/S one to divert any water away from the XYZ switch on the gearbox. Quote Link to comment Share on other sites More sharing options...
dickiboy Posted January 7, 2016 Share Posted January 7, 2016 the front sunroof drain pipes run down the front door pillars but do not come out the bottom the bottom of the pillar is full of grease which blocks the exit hole, the pillar fills up with water it then comes through the hole into the foot well where the wiring loom from the door comes through, if you take the kick panel of you will see where the wires are, what I have done on both of my d2s is to drill a hole on the outside right at the bottom of the door pillar you will have to do this with the door open and you need a long drill bit so you don't hit the door with the drill, when you have done this pock around inside the hole with a wire coat hanger and you will find it full of grease and water all you have to do then is dry your carpet and keep your new holes clear as grit gets washed down and mixes with the grease and clogs it up Quote Link to comment Share on other sites More sharing options...
