gwanyerselsun 1 Posted October 21, 2009 I went into the 205 today and there's an inch deep puddle sitting in the drivers footwell!! The car is has a factory sliding sunroof so I checked the drain holes on that to see they weren't blocked, I ran a bicycle gear cable all the way down both holes and found no blockage, I have also felt all around the underside of the dash for wetness and also found nothing there. The only thing I can think that may be causing this leak is that I have removed the door card from the drivers door and that maybe water is running down the inside of the door in heavy rain and dropping onto the carpet. What do you guys think? Cheers Share this post Link to post Share on other sites
miamichris 9 Posted October 21, 2009 maybe your heater matrix has packed in? Share this post Link to post Share on other sites
DamirGTI 327 Posted October 21, 2009 I've cured leaks on my car by sealing up all the rubber seals with a tube of clear silicone (door seals , window seals , boot seal , windscreen seal) , removed all the rubbers out (bar the windscreen one) cleaned the seal gaps with paint thinner , cleaned seal mating surfaces on the bodywork as well , then smeared silicone all around inside the seal gaps and refitted them back .. afterwards i've sprayed the seal outer areas with silicone spray and since then the insides of bodywork is 100% bone dry Damir Share this post Link to post Share on other sites
Gentry_Ba 1 Posted October 21, 2009 the heater matrix is my opinion, too... on cars with left handed steering the tubes to the heater matrix are on the left side- is it the same on right handed ones? if it is, then I don't think the matrix is blown. the water would have been on the passenger side then... cheers, matthias Share this post Link to post Share on other sites
DamirGTI 327 Posted October 21, 2009 (edited) If it's a leak from the heater matrix then you'll surely notice drop in the expansion bottle coolant level … and greenish color liquid appearance Anyway , i've had one of this footwell leaks before and the cause was leaky windscreen seal right down at the bottom corner of the A pillar ... sealed up the seal from both the bodywork and windscreen glass side with sealant and job done , no more leaking afterwards ..

johnsimister 10 Posted October 22, 2009 Have a look at the junction of the chassis rail to the bulkhead under the servo. If spilt brake fluid has destroyed the paint, rust sets in behind the seam sealer and the bulkhead rots through, letting water into the footwell. With all rust removed the hole can be plated from the inside once the carpet and soundproofing are well out of the way, and the seam sealer + paint reinstated. You just have to hope the chassis rail itself is still solid. John Share this post Link to post Share on other sites
GLPoomobile 958 Posted October 22, 2009 (edited) Oh joy, you know winter is coming when the flood (no pun intended) of topics about damp foot wells starts No offence gwanyerselsun, but this exact topic has to be in the top 5 most asked questions in this forum's history. It may take you a while to get used to using the search function (there is advice on how to get the best out of this in a few topics within the Questions, Comments and Suggestions sub forum), but if you do use the search, you will find bloody loads of posts about internal leaks. And when you break it all down there is really only a handful of common causes (I could have probably listed them in as many words as I've already typed, but I was in the mood to be patronising ) EDIT - just noticed your join date, and you're not even a newb! You should know better. Naughty boy. Edited October 22, 2009 by GLPoomobile Share this post Link to post Share on other sites
Simes 248 2 Cars Posted October 23, 2009 In summary Heater matrix - liquid tastes sweet (don't ingest though) Rear window seals Boot seal I reckon it's going to be one of the top two. Check under your rear seats, you'll find a rust patch and perhaps a puddle of water. Share this post Link to post Share on other sites
Hardgraf 0 Posted October 23, 2009 Make sure it's water & not coolant. If it's coolant then likely the heater matrix has leaked. Replacement is a job which can only be described as a buggerisimo... Share this post Link to post Share on other sites
