Hi all, somewhere my 1994 Audi 80 avant is letting water in but only on the passenger side, both front and rear carpets are very wet, I have had wife in car looking for leaks as I run the hose over the roof and doors but nothing showed up, the drain hole for the sunroof is clear. I suppose it could be getting in the front and running back but any clues as to where I should look next?

Check the heater outlets either side of the centre console, that's where my old 80 was leaking from the heater matrix.

All the best,
PB

Thanks PB, but I should have mentioned that I am not losing any antifreeze/water from cooling system, cheers for your quick reply, Jim.

I think it might be somehow getting in at the bottom corner front of the passenger door, not sure how as seals all look ok, so no-one else has had this problem then?

hi try looking at the rubber grommet where the bonnet release cable goes through the bulkhead,as the water running off the windscreen is chanelled by there and down the wing,thats on drivers side so also check the path of water going down the other side and any obstacles that may divert the water allan...

i have read on here before about water coming in through the cabin air filter and through the heater box and onto the passenger floor. maybe its worth a look. you need to take the plastic bit off from the bottom of the windscreen on the passenger side, you dont need to remove it completely, i found with mine that by turning the four clips to release it, i was able to lift it enough to do what i needed when i replaced my cabin filter.

yes, but sometimes they leak....this is my most recent project and on inspection it was leaking through the windscreen - not seen that before on an 80.




also, there are drainage holes in the inner wings, one very close to the air filter housing, its easy for water to find its way through here if theres a build up of muck....

another suggestion is check your sunroof drainage points to make sure they are not blocked (if you have one) they also get conjested and sometimes leak into the footwells

good luck!

Hi again, yes the sunroof drain holes are ok, I took a syringe and put water into the nearside sunroof drain hole and it came out ok under the car, today I took out completely the pollen filter housing to check for leaves at the back and there was a little but not much, drain holes in this area are ok too, thanks again, Jim.

I have water leaking into the car again. However, this time I don't see water physically coming into the car and it's not the same area. Now water is somehow leaking into the front pass. side foot area where the floor mat is and on the side of the transmission tunnel I have no idea idea if this is a leak or vast moisture is building up.

I had similar- heater matrix first time around; it did it again later- turns out the plastic scuttle panel wasn't fitted right- water was leaking through the fan for the ventilation system and through... (noticeable when parked front end down hill).... been ok since- or was (on an old car)

Doh!!!! I've just got in my car for the first time in a week and found the drivers side floor full of water. Looks like it's coming in from behind the footwell trim under where the bonnet release handle is.

It's dark outside but it looks like it could be the rubber grommet that the bonnet release cable runs through. There was also some crap around the drain hole (at least I think that's what it is) going to the wing near the grommet.

Would anybody agree/disagree that this may well be the likely cause? It did rain quite a lot at the weekend.....

The bonnet cable grommet is a common cause of water leaks

Agreed.

I've directed the water that comes off the screen away from that area ....

So, assuming the grommet is back in place, what's the best way to get the thing dry inside? It's my daily driver so I can't take the drivers seat & carpet out. I'm currently using towels but obviously there is underlay/sound deadening under the carpet so it could take weeks to dry out......especially in current weather conditions.

keep the heater set to the floor position and leave it on while driving that should speed it up

I've been doing that and also had towels in the car all day and it seems to have helped already. Looking at the grommet in the daylight I can see it is split so I'll get some clear mastic or something to seal it up temporarily.

Does anyone know where I can get a replacement from an/or a part number for the grommet? I'd like to get it done properly rather than leave it as a bodge it & scarper job!!!

Looks like a fiddly job too, is it a PITA to undo the cable & thread the grommet over the length of it?

Cheers

Lee

grommet is 893 823 591 A

to dry the car out, you're really looking at a dehumidifier and hope for a dry day to allow you to run it for a full 24 hrs at a weekend.

To do it properly, removing the carpet and underlay is the only option - they can be dried over a radiator

been there when my heater matrix deposited its entire contents in the passenger footwell.

Removed the carpet and seats on a Friday afternoon. Ran the dehumidifier all day on the Saturday. refitted everything again on the Sunday

A Lot more water sits under the heating ducting under the carpet and sound proofing than you think. I took all my carpets out and found about an inch of water in the floor pan. I have been running the car about without carpets. I found on the drivers side that the water is running down the door rubber on the A post the were it bends to follow the seal it runs in there. But most of the water is coming in at the same point but on the B post. You can see it running down the B post rubber and poors in at the bottom. Its also coming in on the passanger side at the bottom of the A Post aswell but not as bad. I'm thinking of fitting a bilge pump.

I have the same problem, but only in the rear nearside footwell.

I've checked all the seals and they appear sound.

Any suggestions?

Try removing the plastic kick trim off the seal. Then you can see the base of the B post where the water will be coming in. Or it could be coming in round the rear lights.

Argus, I had the same symptoms, Near side rear footwell was very wet, but looks like the water was coming from the bonnet pull cable grommet which had been pulled through leaving a hole. there was water under the drivers footwell but not as noticable at first. fixed the grommet back in place and no problems since.

Wilsy, I used waterproof kitchen sealant on the grommet in my coupe when it split & fingers crossed no leaks for months, even in the heavy rain we had for days on end a month or so ago. It's also flexible so won't split when you open the bonnet.
Of course, replacing the grommet would be better, but in this weather.....brrrrrrrr!!

Nice one Bungle, I'll try that stuff, the rubber seems OK, just needs to be stuck back in position, the pull lever had become disconnected from its mount and that caused it to pull the grommit through i think. Glad to have found the cause as it was a nightmare there for a week driving around in a steamroom!
