Hello there.

Looking for a little assistance in tracking down a wet rear footwell in my 2014 golf cabriolet. I will also share what I have done to try to help any others as I cannot find a single thread anywhere specifically relating to the convertible.

A couple of weeks ago I went to hoover out the car and noticed the rear passenger ( right hand drive ) was soaked. The removable floor mats was dripping wet when I removed it. I got out the wet and dry vac , about the size of a henry and sucked up what it could. It filled the machine. I had driven through some small floods and presumed that was the cause. I put a towel in the footwell and some kitchen towel on top to see if the roof itself was leaking from the awful rain we have all been having. The kitchen towel was dry next morning so I presumed the roof was not obviously leaking.

Next day I had another wet vac session and got loads more water out, I thought I would have a look and see what the front passenger footwell was like, this was also soaked like a sponge. Again I used to vac and pulled the carpet back as far as I could and lifted the rubber sponge membrane right at the front. All this was soaked. I dried it out as much as possible with full heat on everywhere I went and then a dehumidifier when at home. Eventually it appeared dry so I put it back together.

At this point I tried to clean out the plenum? chamber at the bottom of the windscreen which was full of pines and leaves etc. I presumed this was the problem and poured a bucket of water down the screen and could see the water coming out nicely from behind the engine. My pollen filter was bone dry and I presumed the problem was either this , or the floods from the week before.

Unfortunately for me I have just been out again and the rear footwell is getting wet again. It seems to start from the middle of the rear footwell( perhaps slightly more towards the door and slightly more towards the rear seats) as the front is bone dry at the moment. I cant see any obvious trickles around the door seals and the carpet directly beneath the door feels dry. I am not sure if the water is coming in from the road when driven ( although the water that's removed always looks clean) or from the rain. Im not using the car tomorrow so if it rains I will hopefully find out , if the wetness is worse. I am also going to remove the rear seats and peel back the rear carpet. But I would really appreciate any suggestions on where this could be coming from please?

Hello.

I have some possible fixes to help. I have tried numerous forums all over the UK , read many German forums and created one hoping for help on a German forum. I received no answers unfortunately.

One of the German forums posters even said that they visited a major dealership and 10 out of 12 golf cabs had water ingress.

I have taken loads of pictures with the intention of making this thread a possible fix page.

Do you have any water in your tyre spare wheel well ?

If you don't have one already getting a cheap wet and dry vac will really help sort the problem out. Some of the prices people paid at dealerships for part fixes is scary.

The first thing to do start getting this fixed is get your rear seat bench out and get the carpet up as much as you can to dry it out everywhere. Before any mould starts growing.

I used the wet and dry vac everywhere I could and shoved it right under the front seats, then get a powerful hair dryer or warm air blaster and get it all dry. Mine is now bone dry with no smells and I managed doing it without the removing the front seats.

Place some towels in the footwell near That green wire clip to stop the carpets getting wet again and prevent more water getting to the control systems under the rear passenger seat.

Leak had spread spread right to the front of the passenger side in mine and behind the carpet right at the front of the front footwell is rubber membrane with foam underneath. Without being lifted up and dried underneath it would never have dried on its own and soaked up water better than any sponge .

With the rear carpets pulled up a bit and the front seat forward you can see the green passenger wire clip from the drivers seat. If you get up to speed and then do a hard stop you can see where the water pours in next to the clip. Like in the next photo.

Hi
Thanks for taking the time to reply. We first noticed the carpet was damp in the rear passenger footwell in early autumn. We didn't do anything about it and after a period of really heavy rain we had a swimming pool along the length of the passenger side. Braking would cause water an inch or so deep to rush up under the glove box area.
I bought a wet and dry vac from screwfix and removed 10 litres of water. Over the following days I removed more by taking out the back seat and pulling the carpet up along with pulling back the carpet and rubber at the front. As we park the car under trees I guessed it was coming in from the front and worked to the back but due to the rubber insulation at the front we hadn't noticed. I took off the wipers and the plastic and cleared out the drainage area below screen. It was full of leaves and muck and I thought I'd sorted it. However the rain has returned and with it our soggy carpet. It seems to be starting from the rear passenger side.the front still feels as it was.the back is soaking. My fear is the hood... Seals are £300 a corner I think. I have pulled the carpet back in the rear and have a towel down which I wringe out daily. This weekend I plan to take the passenger seat out and lift all the carpet up. Previously my partner sat in the car with the carpet pulled back and I pressure washed it and we could not find any water coming in. Maybe with all the carpet pulled back we will have more success. Unless it's coming in from below it must be around the rear passenger window??? I didn't take the spare wheel out but it felt dry around it......

Sorry to hear of your troubles. I have tried three possible fixes on my car, which have largely worked it seems. It sounds to me like you are having the same problem exactly as mine.

A word of caution , if you remove the seat and disconnect the airbag don't turn on the ignition with it disconnected or it will throw up a fault code that will need clearing with bag com or similar computer.

I have also cleared out that area under the windscreen and thought it was fixed as I had an issue with that on my Skoda superb. Check your air filter is dry too at the back of the glove box .

The other areas I have worked on is water in the sills ( bad) , water collection trays and rear boot vents. I'll be writing a guide with pictures later today. Nick

Thanks again for reply. I was going to disconnect the battery before removing seat as extra precaution. I don't want a side airbag going off. However if it is coming down into the rear corner maybe I won't take the seat out... The carpet is always wettest in the corner by the green tag and looks a bit dirty underneath in just that corner. There was also speaks of dirt on the metal going up and under the plastic side panel as if water had been running down

Yes the battery disconnection would have been a wise move !

That sounds exactly like ours.

Water in the sills.

I'm not sure which of my fixes actually fixed or 95% fixed ours so I'll go through them all.

I had been doing loads of searching for fixes and apparently lots of VWs or similar have water in in the sills.

If you look under the outside door sills there are 3 or 4 oval shape rubber bungs. They are very hard to see as they are covered by some kind of coating and road grime. If you feel for them they are obviously softer than the rest of the sill.

The two I worked on are towards the back of the car. One that is exposed is below the centre of the rear window. Use small drill bradawl or pointed screwdriver to pierce the rubber bung. The water from this slowly poured out all day and was still dripping the next day.

The next bung is under a plastic cover that helps support the wheel arch liner. A couple of torx screws part hold this down , it's quite flexible to bend it back whilst another hole is pierced. I parked on a hill and let more water out. I made the holes slightly bigger the next day too and more came out , they must have got blocked.

The next fix ( water collection trays )involves removing the rear wheel arch liners anyway so you might want to do it all together.

The last photo with all the build up dirt seemed to be holding loads of water as when the cover was removed and cleared out my sills didn't collect the water that they did before.

Someone else in Germany posted this who had the same symptoms.

I also used the wet and dry vac inside the larger hole and sucked up loads of water and gunk from inside using this crude but effective suction device ( next photo ). It will be useful later on when I post about the water collection trays.

I used this to vac out the windscreen chamber too.

Water collection trays.

I found a VW TPI ( factory service instructions thing ) which helped locate and clean these out . Unfortunately it's in German but the diagrams were useful. I'll get it up in due course.

If you get your roof open half way like in the picture , and carefully move the roof to the side you will faintly see a plastic box with raised ridges and a hole in the middle. When water runs down the back of the roof it channels to these boxes which then drain through the top of rear wheel arches.

They get completely clogged with all sorts off debris. Mine was full of tree pines. I used the wet vac probe to vac it all out and shoved my finger through the drain at under the wheel arch.

After this I poured water all around the back of the roof and watched it drain through the hole as it should. Apparently if they are clogged they overflow and go somewhere inside the car , but not usually the boot.

Thanks so much. That's all brilliant. It's meant to be dry on Saturday so I'm going to have a go at all of this. Did you remove the back wheel? We moved house 18 months ago and the car is parked under trees so unfortunately we are going to revert to a regular car in the future. the sap and bird mess and leaves and a soft top are not a good combination. Once fixed we will use a car cover frequently particularly in autumn. Can't wait to try the fixes. Much appreciated

Also our collection trays are clear I think as I checked with the hood down. However I'm just talking about on top of the plastic grid. Did you somehow get into it below the grid
