Hi guys, had my 2012 facelift 2.0tdi exeo sport tech estate for a couple of months now. Must admit after joining here and reading about the plenum issue I never checked until today. Well, I haven't had any issues regarding wet foot wells etc but I did notice a load of wet leafs and all round sogginess under the bonnet today but......not near the battery. I only seemed to have issues at the far left of the engine bay, (if your standing in front of the car looking towards the battery it's to the far left) I presume this is where the leafs have gotten in as there seems to be a space where the bonnet meets the windscreen in the corners. My question is, is it normal for it to be wet under here? It's not swimming just really soggy. I've cleaned out what I can with fingers and hoovering and took quite a bit of leafs/crap but was just wondering if I need to do anymore or take it back to seat as it's under warranty? A few bolts etc are looking like they've rusted/rusting. Nothing to worry about or potential issue? Thanks in advance guys...

Hi Guest we, are working on an upgrade to the forum this week, meaning the service may be unreliable at times and there will be some planned downtime at some point. Stay updated on this thread.

Water ingress under the bonnet? Help!

Don't think that is the correct terminology as surely if it's a bung the hole is already blocked as bungs are used to block up holes I would say it is a grommet
Then you should have said duck bill valve then and I feel the need to correct your spelling it should be loser not looser and it takes one to know one
If you look in the bulkhead where the battery sits you can see a large oval bung if you reach under the bulkhead you can push the bung out from underneath then just take it out it leaves a nice big hole for the water to escape,it's the best way to do it without removing the battery and the duckbill valves have a habit of blocking up again.i have done it on mine and never had a problem of the bulkhead filling up with water.
Thanks for all the advice, I've got a years warranty on the car from SEAT from when I bought it so am going to ask them to have a look at it...
to be fair I would say that it is not a warrantable item, neither is it a service item if the car is parked a lot under trees etc the valves will get blocked if you haven't had the car long then they may look at it for you for free once but to stop it happening again I would remove the large bung as mentioned before then you won't have anymore problems.
Loads of makes and models of cars get blocked up air chambers and scuttles from leaves and debris
its part of a service that they should be cleaned out
problem is so many don't do it so you cant blame the car because it hasn't been serviced properly ,
The fix for these cars like others under the VAG brand is simple as already mentioned
Pull out the bung under the battery tray which you can feel from under the bonnet in the same area just above the steering rack
Problem then solved
Close the bonnet and be happy it will never happen again

Ok guys a bit of an update...
I bought the car from a dealer a few hundred miles away based on condition service history etc. I took it to my local seat dealer this morning under warranty which they argued as mentioned above, that it wasn't a warrantable item. My argument was I bought the car 3 months ago and can honestly say I've never parked it under a tree etc as where I live, there isn't a tree in sight! Anyhow, they cleared the two bungs as they were indeed blocked and they removed and replaced my pollen filter as it was soaking wet and had lots of leafs etc on it. The guy said it's the first we've seen of this problem but we'll be sure to keep an eye on other exeos now. So as it stands I have two bungalow which are clear but have not been modified. Now I'm aware of the problem I will make sure I don't park under trees. Do you guys think this will be enough or should I just get the modification done? I don't really like messing with stuff as generally most parts have a part to play and I thought I read the bung allows water out and gasses not to come up into the engine bay. Anyhow I'm not a mechanic so can't be sure...

Hi, I think it's a case of, if your car is parked under trees a lot, the more you will have to keep an eye on any water build up. My car was affected when a 4x4 went through flood water in the opposite direction and totally covered my car, I think it was the silt in the flood water that blocked the bungs. I had a local repair shop remove the battery but said they could only find the bung under the brake servo, so this was cleared and the water drained away. Recently I had the battery renewed and they were aware of the bung under a removable tray which was blocked and cleared, the bung under the brake servo was still clear after 3 years. As you say, the bungs are there for a purpose, to let water out and prevent gases coming in, so you either remove, or just keep an eye out for water build up as I do....Julian
This is what I'm leaning towards...I service my cars once a year so il ask the garage to check it every time it goes in and il be mindful of where I park...
a year is a long time to wait in between checks it is not a case of minding where you park as it isn't always leaves that block it,i have had my car a year now and it was clear when I bought it and I don't park under any trees not for the blocking fact but I hate having tree sap or bird crap on my car and mine blocked up with just general road dirt etc,i would just remove the big bung I have not had any gasses getting into the cabin and you don't want to be worrying everytime it rained that it was filling up with water what if you went on holiday and left the car for a fortnight and it rained everyday and filled up without you knowing,if you remove the bung you will not have to worry about it ever again.
This has been an issue since 1997 when the b5 a4 came out
I have owned many variants of this set up and with all of them ive pulled the bung out under the battery as a precautionary measure and in over a decade have never had any smell or fumes in the car , how much fumes do people think comes directly off an engine ?
Again pull out the bung but if you insist on leaving it there and park near trees clean them both out especially over the autumn months .
But just remember if it floods the plenum chamber the water can get deep enough to go through the pollen filter it then goes into the car under the mats and under the mat on the N/S is a comfort control module which controls a load of stuff on the car and gets ruined by water
I have seen this module flooded a couple of times on cars over the years because people dont know so the bungs were not removed or cleaned out regular
Pay your money take your chance as they say.
On another note if the dealer above has never seen a seat exeo with plenum chamber water i would worry about using them , even audi themselves issued a recal over 6yrs ago about it .

This sounds worrying about the water in the pollen filter, my pollen filter was soaking wet yesterday! I haven't had any water come into the cabin as of yet though? Maybe I just caught it in time?
This was the state of my pollen filter yesterday, completely soaked...

Nasty
You wont see the water on the carpet thou as it goes underneath the carpet from under the dash
The insulation and carpet is about 30-40mm thick the comfort control module is underneath that again
Hopefully you only had a dampness on the filter and no ingress or quantity of water .
The only way you will check for water is lift the carpets
You won't get far enough down with a finger too reach the comfort control module
Only thing is you have too remove the seat and sill plates etc too lift the carpet which isn't a five minute job mores the pity.

Il check the carpets first thing in the morning...I've been blasting out the heater via the footwell for the last few weeks thinking if there is any issues maybe this will help dry it out. Now the bungs have been cleared and pollen filter replaced hopefully I can dry any excess water out...I did say hopefully!

Have you ever stripped an a4 / exeo out
If you had you would know the carpets and insulation dont get wet at all before the comfort control module gets soaked
I give up here ive only been working on cars for a living for 30yrs and into audis etc for 20yrs
So crack on as im done trying too help you wait for your carpets in an a4 on the passenger side too get that wet see what happens
So much for trying too help theres always some keyboard warrior knows best
