2005 jetta tdi water leak.

[Anthrax91]

My gf's 05 jetta has a water leak. Whenever it rains all the carpet ( passenger, driver, front and back ) become very wet. The car will also idle really rough but will stop after driving it for a couple minutes. I'm not sure where the water is coming in at but the floors are soaked and water is getting somewhere to cause the engine to run rough. I know the clogged sunroof drains are a common problem on these cars but those all seem to be fine. Any ideas?

Thanks.

Jetta leaks

I had an issue where the sunroof drain would overflow and leak down the A Piller on the driver side. It would drip all over the fuse box. I would suggest opening the sunroof, remove driver side end cap and pour water slowly down the drain and look for a leak. I ran weed wacker line thru mine which helped unclog them.

I tried that and they weren't clogged at all. Still have the same problem. Im not familiar with these cars so I have no clue where to go from here

The problem most likely is the drain line which runs from the sunroof to your wheel well. This is a known issue and you can search this forum.

Basically you need to get into your headliner and locate where the sunroof drains attach to the sunroof. It will be a white grommet attached to a tannish hose. What happens is the bond between the grommet and hose breaks down and allows water to drip into the headliner/pillar area. Which uses gravity to run down and eventually soak the carpet.

What I did was to use clear silicon and basically re-glued the hose to the grommet. I had to do all four (4) connections.


(VW lost a class action lawsuit for this exact issue)

interesting, yours is in the years.
but it wasn't about the tubes coming undone, just the clogging.

mine, 2006, also leaked from the tubes, and once those were glued back it stopped doing it.
