Water leaking in the boot
« on: July 24, 2011, 09:22:56 am »
I've got water leaking in the boot, seems it only happens when I wash it?
I've had a good look round but can't seem to find where it's coming in, the only place I can think of is the seal for the boot, there was abit of water sitting on the plastic on the other side of it.
Has anyone else had this problem??

When seeing your topic I thought, rear washer pipes leaking?

Maybe the foam seal between the tail light and bootlid?

Mmm I've had a look at the seal and the light, I've put some extra sealant around there.

Well I've had a look on google seems there could quite a few reasons, I've done the rear light, there's seems that there's no grommets out of place, so it was out with the spare wheel and the side carpet and I got the hose out.
I notice water coming in from some sort of vent that sits behind the bumper, so back out with the sealant, hopefully it will sort it.  :smiley:

There's two umbilicals that go from the vehicle body to the bootlid near the top, one on each side. These can fail and allow water ingress into the spare wheel well (this is what happened on mine). Remove or seal with silicone sealant and clean up the boot and cover in POR-15.

I had the very same problem, traced it to the drivers side rear quarter body vent.

Removed rear bumper, removed vent, initially, I applied a bead of silicone grease, worked for while then still let some water in. In the end got a new vent, comes complete with new seal, I  coated this with silicone grease, to try and give it some protection.

Silly Germans used a seal that absorbes water :stupid: so over time it perishes and fails.

Did the other side also. Got the hose pipe out then drenched the area in water. :happy2:

Regards.

I had water coming in through one of these. Luckily just reseating it cured my problem.

It had already been in to VW to have the vent behind the bumper replaced as that is where I saw the water coming from, but it was actually coming in through the rubber umbilical and running down on to the vent.

I had water getting in the boot took me a while to find where it was coming from but found it after a little scrolling on the Internet. It was getting in the vent behind the rear bumper it's there to let air out when you shut the boot. It's located on the drivers side conner of the bumper. You will need to take off the bumper but it's fairly easy only a 20 min job. I'll try finding a picture of it tomorrow

Thanks guys for all this info, managed to do the vent from the inside of the car, I put loads of sealant around it hopefully that's the end of it.

Could you get to this vent by removing the rear wheel arch liner?

The vent is tucked right up behind the bumper, removing the arch liner would only improve access to the front side of the vent.  Easier to just take the bumper off to seal all the way around the vent.

Plus if the seal has failed on one side I would be sealing the other side vent at the same time.
