Had this on a 2006 A6. It was down to some wells being blocked which acted to take away rain. May be similar.

Also seen reports of leaking sunroofs being an issue - although not on the Mk2 Tiguan..

 

Not sure where the water matrix is or even if they have them on new cars but had this once and thatwas the problem it had gone and all the water leaked into the floor of the car. But no matter what it's a trip to the dealers for sure, hope you get it sorted, and keep us all informed as to there finds pls

 

I would take it to dealer ASAP regardless. The problem with the amount of water you are describing is that it will have soaked the sound-deadening material that lies under the carpet. This usually has a rubber backing and so will never fully dry without taking the carpet out of the car. While the actual carpet may eventually feel dry, the underlay will remain wet along with the floor pan underneath that. After not too long you will have mildew and the car will smell.

I speak from long experience of the very leaky mk4 golf that sprang leaks from blocked sunroof drains, door ancillary carrier seals, pollen filter cover and more.

Sorry to not have better news, but suggest make this your dealer's problem

 

Hi Tigger, I had the same problem on my rejected first Mk2 car, it was the sunroof. Car had to have a new frame apparently. Water was running down the inside of the pilars either side of the screen and filling up my front foot wells. Feel your pain mate. Another sign I found which identified the roof problem was when you open the roof, the pop up wind deflector was soaked. Hope they get it sorted, my dealer did, but rejected car as wasn't first issue with it.

 

I had water in my front footwell on my Fpace i owned, I found it was due to the way they rain the washer bootle pipe to the rear windscreen, there was many small pieces held together by cheap clips, have you checked your washer bottle to see if this has emptied?

How long did you have the car before the final rejection. Always good to know.

 

This is common on all the VAG group cars! This is caused sometimes by freezing. behind the door cards there's a baffle that caries all the window winder equipment ect, this has a seal around and it is to the door, this what leaks as I said in most cases caused by water freezing in the seal and expanding spoiling the seal, much like a frozen pipe it's a easy fix albeit fiddly as it's easy to break the door card clips and these are something like a £1 each sugest let the garage do the job if it's a new car but if it's out of warranty a very small amount of silicon sealant does the job

 

Wow, lots of interesting answers to this - thanks all!

I will be having a look at the sunroof again, as suggested, and interesting one about the washer bottle, although I don't think it's this as the water has no smell, which I'd have expected the washer bottle contents to have as it's a fairly strong solution of antifreeze following our beastly winter.

The freezing window seal idea could very well be the cause, especially as it's the driver side window which I often have to wind down even when it has a bit of ice still on it, to exit the secure car-park at work. I'll mention that to the technicians at the dealership when I take it in.

I have today had a quick look and noticed a bit of white mould present under the driver's seat, so it's certainly not a very recent issue, must have been developing over time.

Anyway I've booked it in for next Thursday and they've got it for all of Friday too, so let's hope it can be traced.

If you open the door you think may be the problem and spray water on that door window you will see some water coming from some holes in the bottom of the door, this is good if you see water coming from between the door and door card (inner covering) that is bad

 

Tigger, have a look at bonnet release handle, I found water was finding an exit route via this.

 

Stanleycats, bought car in March, was replaced by dealer in July (would have been sooner but wife in hospital so car last thing on my mind).Had also broken down on day one of ownership, new fuel pump required. Then had my new 3rd tig in October, I must hold some sort of record!! New one is faultless after 5000 miles thankfully!

 

Ok, just a quick update after carrying out some hosepipe tests:

Water on door windows runs away as it should, outside the sill and not into the car, so that seems to rule that one out (sadly, as it would have been an easy fix).
Water on front windscreen and bonnet area seems to cause no ingress round bonnet release handle area or anywhere else visible.
Water on sunroof again *seems* to cause nothing - but if it's a small amount and it takes a while to work its way down a pillar to the floor, then perhaps it could be that.

The other thought is whether it's actually driving on waterlogged roads and through puddles which is causing some splash into an area up front causing problems - difficult to test that one out though.

Fingers crossed the dealers might just have dealt with a similar issue and know where to look - but my current experience with dealers so far is that every problem seems like it's never ever happened before in the history of motoring... :lol:

 

Another quick update:

Dealer is keen to diagnose this properly and not send me away with what appears to be a fix but isn't - also they currently have a 17 plate (mine is 67) awaiting similar repair so are obviously hoping both of us might have the same issue. Service chap reckons it could very easily be all of next week by the time it's found, fixed, and very possibly new carpets fitted.

In any case, taking delivery of a temporary replacement vehicle today, also a Tiguan - the service getting this sorted out has been very good - the only thing is it's a manual so I'm going to have to remember how to change gear...

Very doubtful if they replace the carpet as you have to take vitally everything out the cabin, but don't worry as they will most likely do a very good interior valet and there vac will take almost all the water out

Almost, you want to ensure it all comes out, having had a washer bottle pipe burst in a previous car the sound deadening was soaked and the only way to dry this completely was to remove the seats and the center console and take the whole lot out, I would not expect anything less personally otherwise a damp sound deadening will cause smells and possiable issues with rust and water damage under this material.

 

- the only thing is it's a manual so I'm going to have to remember how to change gear...

The changing gear is easy, it's remembering to put your foot on the clutch and change fear quietly that's usually the problem. As I have crunched the wife's car gears a few times recently. Lol.

Not as bad as going from a manual to an automatic. Got an automatic loan car and after leaving the dealers I tried to change gear and nearly went through the windscreen. :roll:

Our dealer refused to have anything to do with us after our second :lol:

 

Dealer is excellent, in fact, they game me my 3rd car without a request from me, and upgraded to a 190 engine with keyless and electronic boot. They evidently contacted VW who stumped up the extra £2000 for the unprecedented grief I'd had.

I was only telling my wife straight after I posted how good your dealer must be.
Apart from your present troubles, a great service.

 

Had a call from dealer today.

They think they've found the problem and it's something to do with the area that a wiring harness and air conditioning comes through the bulkhead, normally a grommet keeps rainwater running down there out but on mine it isn't doing its job. Half the dashboard has had to be removed to get to it apparently!

Well that's the gist of it anyway - the upshot is that a new part is coming from Germany, and they WILL also be fitting brand new carpets as they have said that even a decent vac and dry could leave areas of mould or damp undetected, which they don't want.

Parts arriving Friday hopefully - on Monday fitted and Tuesday a 'water test day' to make sure it's been fixed.

Interesting, the Tiguan I'm using in the meantime is a 150 manual and I'm getting 5-10 mpg better than on my own car. Being manual it still accelerates pretty well in the right gear when needed as well. If I didn't spend half my life stuck in traffic jams I'd probably still go for manual gearbox, but in stop start it's a lot easier on my left knee with the DSG.

Let's hope this is the issue which is good news and also hope you do not have any dashboard rattles after they have finished the work, keep us posted on progress ect.

 

good luck hope it's a go

 

Good news.

Got the car back today - all as promised, replacement carpets and mats, no smell, no damp. And a very clean interior as well as exterior too, thorough job. Best of all, all my various settings haven't been messed with, including mirrors, seat and display, and my dashcam wiring has been replaced 'as left' following the removal and reinstallation of the dashboard.

The mpg of 45-48 is a bit galling after two weeks of getting 60 mpg, but the courtesy car was not 4WD or a 190 or a DSG, so all those things add up, I'm guessing.

Anyway I think it only fair to give a mention to Listers VW in Worcester, who have been thoroughly professional and sorted this issue out with no drama.

At least, let's hope it IS sorted! :shock: Sounds like it though, they've done extensive testing since the repair and found no ingress occurring.

Fingers crossed and nice to read they appear to have done a great job and looked after you.
