Good afternoon all,

 

Long time lurker - first time poster!

 

I have noticed a damp and musty boot for a few weeks that has now got progressively worse. After heavy rain it drips (a lot) from inside the boot lid through the driver's side knob (see picture).

 

What I know so far (from ruling out things from other threads and the internet)

 

• It isn't the rear wiper as I took the boot trim off, sprayed it and there were no leaks.
• Only the right side carpet gets damp for some reason.
• I don't think it is the light cluster as the carpet around the rear lights are dry.
• I saw that the rubber seal on the inside of the rear window was slightly perish so I have put some silicon sealant there (no improvement).
• All the other boot seals are fine.
• rain channels on the boot frame are all clear and appear to be working fine.

 

So that is where I am at. 

 

Any and all help would be greatly appreciated as I really have no clue now.

 

Thanks in advance, 

 

Rob

Here is a picture of it dripping too. I think that is a clue as to where it could be leaking into the car from.

Three initial questions:

1. Have you checked the spare wheel well for water?

2. Have you checked the bungs at the bottom of the well for seal?

3. Do you park your car in sunlight or a heated area between uses?

Hi Mike,

 

Yes, the bungs had perished so I taped them up, new ones on order. There was a tiny bit of water but not much, I patched them up, dried it and it was still damp a few days later.

 

Yes I do park in sunlight, in an open carpark all the time.

 

 

I was wondering if you had water in the wheel well that could evaporate when the car was parked somewhere warm and would then conbdense on the rear window and run down and into the bodywork.  It may sound a bit fanciful but it does happen.  A good clue would be if your rear window especially gets fogged up when the car is left.

 

We had a leak on our Fabia at o e stage a bit like that and I eventually narrowed it down to the rear screen to rear hatch met work bond failing.  I taped it up with electrical tape between the two along the top and sides as a temporary cure and to check that was it before resealing it with tigerseal. 

 

A few years later we had a simar issue with our old octavia on both front and back screens.

Did you ever resolve the issue on the Octavia?

To be honest not completely.  I did the same and taped up the glass to the frame which pretty much sorted it and then cut a slot in the rubber stops at each corner of the hatch so that any collected water could drain out of the hatch frame outside of the seal onto the bumper.

 

It was on my list to do but we traded it for the Kodiaq...   Which in turn also had a hatch leak that was from the glass to wiper grommet. (sorted now with some sealant under the grommet)
