944 S2 getting wet in drivers footwell, any ideas?

[nick3814]

I've had the S2 since April now and I'm very happy with her, but yesterday I was driving her during some torrential rain for the first time. I noticed once I had parked up at home that the windows steamed up inside and I know from the Lux's that I've had that this signifies moistier inside the car.
Gave her a wash today and found that under the drivers floor mat i have fitted the carpet was wet upto the foot rest on the left, everything around here was bone dry! I've looked underneath and nothing stands out, has anyone had similar problems or any ideas?

Cheers

Might be a blockage in the sunroof drainage hole I think I read something about that before somewhere.

Leaves etc collect around the cabin air box on the scuttle which then block the drain holes and so water ends up finding its way in from other places around there. I make a point now to check around the scuttle when I have the bonnet up and try and clear out the rubbish.

Thanks lads I'll check all that, it just seems funny that its come from underneath as the floor mat was dry [&:]

Large hole rusted through the floor? [8|] Only joking!

Check the bottom drain holes in the door, the sunroof drains and scuttle as usual suspects. It's likely that water is soaking through the carpet from where it gets in, but the mat might have a backing or "scotchguard" treatment that stops it absorbing the water.

I had a similar problem in a 944 turbo, it turned out to be leaking form the windscreen. I'ld get it sorted ASAP in my car the water got into the electronics under the dash and in the end cost me about £700 to fix.

I've checked the sunroof drains and they are fine, draining out the back and at the front under the bonnet.

When I've checked the passenger side it was damp too! It looks as if its coming from the corners of the doors, where the bonnet release is on the passenger side and around the boot release on the drivers side! I've dried it all out with a hair dryer and will have to experiment with the hose pipe at the weekend [&:]

On a similar note, I was always led to believe that the problems with the sills on 944s stems from the drainage holes along the bottom of the sills filling full of debris from the sunroof drains and then they fill with water, again from the sunroof drains, yet its obvious that the S2 sunroof doesn't drain through the sill. Does this mean the S2 was redesigned slightly to prevent this or have I just got my facts wrong and am making a fool of myself........[]

The sunroof drains are (as far as I know) the same on all 924's and 944's and do not go into the sills so I don't think this is the cause (although you could argue that water could run down the front of the rear wheel arch if it came in from the roof area).

It doesn't sound like your problem, but driving the 944S in the rain for the first time I got a very wet leg. The problem was someone had removed an alarm box or similar right above the pedals and when cornering the water would drain straight out onto my right leg. A quick bodge of a couple of self tappers put an end to that one thankfully.

Probably worth checking that the heater drain hose is not blocked too. I had this on my 968 and it got so bad that water was spraying out of the face level and windscreen vents after the air conditioning was turned off.
The drain hose is located behind the stereo and cubby hole in the centre console.

You might also want to check the seal around the heater fan assembly, I have heard of these leaking too.

The cars been sitting for two days now and with this shocking weather we are having last night the alarm kept going off untill I switched off the interior sensors and then this morning the whole car is misted up again []

Checked all around and nothing is particularly wet but then the floor doesn't seem bone dry either!

When I lifted up the drivers over mat the vinyl floor peice around the pedals is damp and the foot rest is quite wet aswell, above this is a large plastic assembly, is this the heater assembly? As that had drips on it and Im wondering if it is coming in through there from under the bonnet!!

My old Lux did this, it took ages to work out how water was getting in. In the end I found a small hole in the scuttle just next to that black canister thing, looked like it should of had a bung in it. Every time I parked on a hill water would run in. [&:]

Nick. My 968 has had a small water leak in a similar place. I found it to be the heater box . A few of the bolts that hold the box to the scuttle [accessable from the engine bay] had worked loose. Tightened them up + hey presto , no more leak....
