Just made a hole in the bung on both sides that are in line with the middle of rear window... Very satisfying as water poured out of both for about five minutes. I think I'm making progress.Will do the others bits at the weekend. If you get a chance can you fill me in on the water collectors and liner removal. Thanks again. So grateful

That's great news ! Really happy to have helped. I'll pop everything I have done to the car down asap.

If yours is the same as mine I would think that water in sills will have fixed most of your problem. I didn't realise until the other day that water that gets on on the passenger windows eventually makes its way into the sills and if they are full it must overflow somewhere in the car.

I poured a cold kettle load slowly over the back passenger window and the hole I made in the sills started dripping again it must be related.

I would keep coming back to those holes and make sure they don't clog up. We had really heavy rain last night and i shoved the screwdriver in the hole again which got some clean looking water out. I need to properly drill out the bungs.

The wheel arch Liner was held in place by 10 or 11 of screws that fit that bit in the screwdriver.

To remove the wheel arch liner the wheel is going to have to come off.

I used the VW jack but I didn't go under the car until an axle stand was taking some of the weight so please be careful.

Some of the screws are a bit awkward to get to and hard to see. The little electric screwdriver with its light and compact size was perfect. I used it later to drill the bungs out as I couldn't get a larger drill to them.

There not much to it, find all the screws careful not to over tighten when you put them back. The liner just falls off when all the screws are out , it's just a big piece of thick felt or something.

Good luck.

The next thing I've looked at are the rear boot vents. In the boot there are two panels that unclip to get to the lights. Inside there is a rectangular ovalish vent. Some have had problems with those , but I think that usually fills the boot up.

Like this

The roof motor is on the left hand side of the cab.

All I have done with these is put some super absorbent cloth around the vents on both sides , they get a tiny bit moist but nothing like that video.

The white circle is the roof motor.

The red circle is where a bit of dirt and moisture seems to get in. Im not worried about this as all my boot dry.

I cleaned it out and put the cloth at the bottom of both the vents to be sure.

Your a legend. Not All Heroes Wear Capes 😁
Will let you know how it goes. I was getting near to taking it to vw £££ but thanks to your posts I can see light at the end of the tunnel. After the effort of buying a puller... Getting the wipers off and sorting the front area I was pretty gutted to find it still filling up but i feel positive about sorting it now especially with the water pouring out today.

Thanks again

Hi
Followed your guide today and hopefully sorted the worst of it. Took off the liner and rubber piece at the bottom of sill on passenger side. Looking inside sill it's damp but not holding water. None came out now that I have the large drain holes. However did find it was damp in the wheel well coming from the left side where the roof motor is. Sticking my hand in behind the motor into the rear wing it's a bit damp. Will have to keep an eye on it. I've put a cloth there for now. It wasn't terrible. Sucked carpets. Undid bolts of seat so I could tilt it back and forward to suck up the carpet beneath as there is slack on the cables. Think it's going to be much better.
not all good though.... Hood opened an inch yesterday and then fault light and stuck. Went through procedure to close manually. Pulled out fuse for hood to clear fault light and message and it worked again but stopped a few times mid way through going back up. Hopefully not connected to all the moisture that's been in the car. Will worry about that in April when it gets used again ??. Will concentrate on the leaks for now. If its fixed I have an odour bomb cannister to put in and set off with the a/c on... then a unibond 360 thing that traps moisture like a dehumidifier to leave in the car... Fingers crossed. Rain forecast tonight so will find out tomorrow

Hello.

I really hope the drain holes fix it for you. Your leak problems seem exact same as mine , perhaps worse.

There's a couple of other bits that I did to try to prevent any other leaks that I'll get to posting.

Sorry to hear of your roof issue. I don't know much about its operation other than the motor location. Something I would look at to help see if there is any water damage is trying your Bluetooth. When I started at this I was worried that the computer under the pass seat was going to be damaged. I think it's the Bluetooth module. So I presume if this is still working then hopefully your roof issue isn't water damage .

Some other vag have a comfort control module under there. I'm told it controls wipers window central locking etc. MaybeHave a check of all those things as someone said it also has something to do with the security immobilizer.

The those dehumidifiers is a good tool. They always worked well keeping the damp at bay in our caravan.

I was looking for something similar but small to place in cupboards etc people said use silica cat litter in a sock lol. It's super absorbent it works good in various places.

When I was reassembling my car I cut out some of that foam underlay and replaced it with some absorbent cloth and Silica. So now if it starts to get damp again I can keep an eye on it and swap the cloths around by just pulling the top layer of carpet back from under the belt rail.

It hammered it down a couple of days ago when my was driving home and happily they were dry on both sides.

Another area I worked on , which turned out to have no problems was the rear speakers. Googling 'rear footwell wet VW golf' brought up 3 door golfs with leaky speaker seals. So I looked at mine.

Getting the the speaker cover off wasn't too hard. I started with the plastic grill bit and slightly broke it as it's not supposed to come off. Removing the larger leather covered segment was easy another though scary as it feels like your going to break it. I started from the bottom and it pulls off. The main reason for posting about this is that there are wires behind the panel at the bottom near where the seat would go. They had gotten a bit wet so I dried them out with the hair dryer and shoved a sock with silica in if down there. The drivers side one is easier to see as there is no storage compartment in the panel below the speaker.

I removed the speaker for a look at the seal , which was fine and dry. When the speaker is out you can see the window regulator , it all looked wet so I dried it out with the hair dryer and gave it some wd40.

Thanks for that. We have had two wet days and carpet seems fine. Before it would of been soaked. Computer under seat is a worry given the amount of water that was in it. Bluetooth is fine as its picking up our phones when we get in. I think the water ingress will cause problems in the long term and unfortunately we need to keep it until spring next year. Roll on summer when it can really dry out!

This is a screen shot from a video after I pierced the rubber bung on the sill. Poured out for ages

I hope that it's staying dry for you. That screenshot looks satisfying and disappointing in equal measure. Disappointing that this should happen to our cars.

Hopefully if your Bluetooth , central locking and windows etc are working water hasn't got in to the unit.

I wonder if it might be worth disconnecting the wires to the roof motor and cleaning the contacts?

Hi both, fantastic info, my wife’s 2012 has the same issues, guess what I will be doing tomorrow with the help of this post. By the way when I was trawling through the websites and couldn’t find anything for the convertible I did pick up in using nappies under the carpet and underlay to suck the water up, they work fantastically but does look weird that I have a pack of 20 nappies wedges both sides of the underlay. And they are cheap! Will let you know I get on with the waterfall in the sills (hopefully)!

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.
Did you ever find the FSI to post up here? I would be interested to see. Many thanks
Mike

Hello.

Yes I have the TPI. It's 10 pages long and a pdf so I'm not certain how to post it.

Easy way is to search for this in Google.

2033888/4

It's the first result on the motor-talk.de website.

Hope the information is useful.

This may also help owners of the A3 cabriolet with water ingress and water leaks.

My left sill was also full of water:

I translated the above vw bulletin and it states water ingress into just the left or right trunk area and not into the passenger area.
So far before I found this forum post I had already checked my pollen filter, cleaned the front left and right plenum drains (cannot see the middle one) , checked the hood drains and removed rear wheel arch liners, and discounted the ac drain as it goes into the drivers side of the gearbox central tunnel. I also had already had the passenger door card and rear quarter card off and sat in the car with a hose on it, couldn’t see any leaks, but resealed the rear speaker.
Still at a bit of a loss unless my only thought is that somehow the sills fill with water and when my wife drives to work up a really steep hill the water in silk was running to either the front and back and managing to make its way up into the floor pan???
It’s currently still full of nappies trying to suck the water out of the sound dampening/underlay. By the way the worst holder of moisture appears to be the rubber/foam panel in the front angle footwell to the bulkhead

My other 2 areas to revisit are check the central plenum drain, if there is one? I have borrowed a puller from work to remove the wiper arms so I can lift the cover and check. And understand why with the air con on I have no evap drain water showing on the drive under the car (blocked and running into car), still not holding hope with this as the drain is drivers side into central console next to the foot rest, and that’s dry!

Could I pass on my thanks to all the above posts. I have been having problems with wet carpet behind the driver seat on my 12 reg convertible. This morning I simple pushed a small screwdriver into the end of the cill where the arch liner ends. Twenty minutes later water was still running out, may explain the sound of water sloshing around I could hear at times. Once again thanks for pointing me in the right direction.
