I had to go thru the same issue and I have a few suggestions for you. What I did is separate the blue hose from the white tip. They where too easy to separate and used silicon RTV when I put them back together for a better seal. One thing you need to remember is you NEED to do the same thing at the other end of the drain pipe. The same crappy two pieces that leaked on the roof will also leak at the other end. You can access the passenger side rear drain pretty easy by removing the rear panel and sticking your hand in there. The driver side rear drain is more involving because the jack holder is in the way. The front ones are not that bad to access by removing the trim part on each side of the dash. On my car the blue tube and the white tip separated in the bottom and flooded the driver side pretty bad. Do yourself a favor and check the other end also they where clogged way worse than the top one and the seal is pretty bad.

So everyone who is having this issue. We need to pressure Volkswagen. This is currently happening to mine and it’s been raining like crazy. I love my 2012 Tiguan Sel. I mean there was a river of water . My car has under 40,000 miles.why the hell would anyone else purchase a Tiguan if this is what’s going to happen ? So disappointing. Awesome content Alonzo and much appreciated . Thankfully you don’t live in the pacific west coast.

I'm a working tech (35yrs.) and this is a great video. Cheers!

Thank you so much!! Just bought a 2011 that we knew the timing chain was broke on, total nightmare fix but my husband is awesome. Also got all of the valves as well but for an $800 car, we were prepared for that. Taking it out for the first time in the rain to a leak, we werent so prepared for. I knew you tube would give me the answers! Thanks!!

Glad I stumbled on this! I just replaced the turbo today and now I know why my front windshield is frosting up inside. 2015 R-line that I love but now I have this to deal with. I'll need to temporarily seal up the sunroof or something to get through winter.

I really needed a step by step with this same problem.

Yea bro!! Thank you very much! Greetings from Serbia 🇷🇸

Can you attach a video of how you removed the headliners?

Hi! I've got this issue with my Tiguan in the UK and once it stops pouring with rain, I'll follow up your suggestions. I've ordered some 3mm strimmer line which I reckon will fit sown the tubes and be stiff enough not to fold with some force on it so that should clear things. Thank you for a very informative video!

Great vid 👍🏻 wish this was a recall ! 😩

Just looking up how to do this. I read somewhere that blowing air down the lines wasn't recommended, but it seemed to help you. My leak is so bad, I'm pretty sure the gas pedal (Accelerator Throttle Sensor - LOL) sat in water and froze. My 2013 Tig is now running in limp mode with a voltage mis-match between pedal and throttle body. Just got a new pedal - hope that was the right side to replace. Oh, and of course I was going to try and fix the leaks first before putting the replacement pedal in. :).

My 2010 tiguan leaks!! Thanks for the video

My 2012 tiguan was leaking into the interior and every time we had a storm it a small lake would form on the floors. Turns out that the drain tubes shrink over time and became disconneted at the ends leading out of the car, causing them to leak into the interior. I took some pieces off to reach the drivers side as well as the two in the back and ended up cutting a few long thin funnels in half and placed them into the drain holes, and then fed the drain tubes into those. That has ultimately solved the issue and my car is no longer a bog!

So I too am having the dame issue on my 2012 tiguan. I bought it used from a friend who is a broker. I have had it in to the mechanic. He said he cleaned clogged lines and I shouldn't have another issue.i took it thru the car wash and it was leaking from behind the hood release handle and onto the floor. Still an issue but the water just moved to a different spot. My friend replaced the headliner as it was damaged but didn't check to see where the leak was coming g from. I'll never have another car with a panoramic sunroof again! Lol

Would it be easier to pour some sort of drain cleaner into it to dissolve the gunk rather than going at a rubber tube with a piece of metal? Just thinking if you tear it, its pretty much game over for having a dry interior

Thanks for the tips!!! I did think about getting a thin fibre glass rod to rod them through but the compressed air seems a great idea & might not disturb the pipes as well!! Good work & could you please let us know if it was successful.

The drain are clogged on firewall behind front tires remove weel well to access, rear drains are behind rear wheels

My backs are leaking. 3 months ago it was the fronts. Get under bonnet a pull the spider traps off. It sorted it

I have a 2015 tiguan ,that I also have to clean the drain hose, did you take the hose off and blow air from the sun roof to the open drain to unclog it, or did you just use water. Not white and blue hose , the drain on the sunroof, at the 4location, your video is pretty good but I liked to see how the panels and liner came off, but your video still gives a lot of information .thk you

Thanks!

Would that be the same when I have my passenger side carpet wet?

You could use garden strimmer line to clean out those hoses maybe?

How super simple were those front panel clips?

Update? Did it fix the issue completely? Thanks for the video though! I think this will help us!

Awesomeness homie!!! I own a VW rabbit that leaks like crazy without a sunroof. It’s a total nightmare!!! Looking to buy a 2015 sportwagen tdi with pano roof. I’m so scared it might leak as well. From the looks of it, many are having problems like yourself. I might pass on the sportwagen now 😢. Did your problem resolve after you did this? Great video btw!

Wish you showed how to lower headliner

Are there can you get to the upper portion of the drains through the sunroof ? Or you have to pull the headliner?

I have a question. Is the same with car without panoramic roof?

So how did you remove the trim? Isn't this a main factor in the video?

The worst part of this is these Tiguans still with those problems of leaking water 😔😭. I bought in September a Tiguan 2022 and guess what???? RIGHT NOW is in the dealer with the same issue. Idk I feel so sad and I’m thinking about to change it for a Atlas without panoramic sunroof 😵‍💫😞😭

Could I just plug up these lines in general? I don’t want water running through my vehicle

How long did the whole process take from taking off the head liner

Why did not post how to take off the liners??

Great bid except you missed showing us how to detach the roof lining :/

You skipped the headliner removal and just had a hose in your hand. Not sure how to do it.

had this blockage on my Passat B8 GTE, water then ran into my PHEV wiring loom at the bottom of the A-Pilar, resulting in up tot 2000€ worth of damage. because of this stupid plug and the lack of checking this at the dealership each time the car has to go in for routine check-ups. VW and AUDI know of this problem, the internet is FILLED with sunroof drain issues but the like the €€€ it provides i guess. I'm having my car repaired, the sold of. No VW for me anymore.

What year is her car

Common problem with a Panoramas sunroof everybody thinks it’s a seal, but it’s the drain

just chane all those tubes are the best solution rather than use glue.....

Strange, drain behind the liner. Why not have the car waterproof from outside?

If I can’t do this myself, who would do this kind of work? The VW dealership is not an option.

You don't have to drop the headliner. There are drain holes at the top of the sunroof.

Tiguan may be the worst car ever made by VW. -timing failure -oil leaks -power steering issues -low oil pressure issues -roof leaks

The problem could be fixed with 10 minutes easy job cleaning the small conduit rubbers gum at the front/back. Take a look to this videos kzfaq.info/get/bejne/aK1yZNZeqtfJcX0.html - kzfaq.info/get/bejne/h96Xi86n2d65eZs.html

This issue is still present in most Gen 2 MK2 owners as well. Super disappointing to know they engineers did not address this on the Gen 2 Tiguan after seeing all the numerous report of this issue on the 1st gens. Once again German over engineering failing in real life.
