whippg Posted April 20, 2009 Report Share Posted April 20, 2009 Hi All My 2005 B7 A4 Avant has started to emit that musty 'wet dog' smell from the air con. I'm going to get a can of Wynns Airco Fresh to sort it out, as I've used it successfully on previous cars. My question here is - Where is the internal air inlet located on the A4 ?:confused: - as the directions tell you to spray the can into this inlet after setting the air con to recirculate mode. I've looked in the car itself and in the manual and I'm buggered if I can find it - it's not obvious. Any help you guys can provide is much appreciated Link to comment Share on other sites More sharing options...
blackpool1974 Posted April 22, 2009 Report Share Posted April 22, 2009 Behind the glovebox Link to comment Share on other sites More sharing options...
irishejit Posted April 22, 2009 Report Share Posted April 22, 2009 funny you should say that...mine started giving off a smell yesterday Link to comment Share on other sites More sharing options...
whippg Posted April 22, 2009 Author Report Share Posted April 22, 2009 Cheers for that. So does that mean I should be able to access the inlet from the passenger footwell under & behind the glovebox? Tell me it's not a glovebox-out-job to get to it Sorry to bug you, but I obviously don't want to waste a can of Airco Fresh if I'm not squirting it into the right hole (so to speak) Link to comment Share on other sites More sharing options...
blackpool1974 Posted April 22, 2009 Report Share Posted April 22, 2009 Well I noticed the vent when I had the glovebox out, put it that way !!! If you stick your head under the glovebox I would assume it would be visible I didnt bother with the expensive aircon spray 99p special offer from Tesco, Dettol Anti-Bacterial room deoderiser spray !!!

irishejit Posted April 22, 2009 Report Share Posted April 22, 2009 so is this caused by the pollen filter going done then? Link to comment Share on other sites More sharing options...
whippg Posted April 23, 2009 Author Report Share Posted April 23, 2009 Cheers again for the response. I'll take a good look under glove box - sure I've just missed it. With regard to what causes it - I'm no expert but from what I've read it's to do with stagnant water collecting somewhere in or around the aircon unit breeding bacteria giving off the wet dog smell. There are other more detailed posts on here if you search. Airco Fresh sorted same prob on my last car so I'll stick with that. Also the handy extension pipe makes it easier to get the spray near where it's needed Link to comment Share on other sites More sharing options...
maersk Posted April 26, 2009 Report Share Posted April 26, 2009 Just set the can off in the passenger footwell, close the doors and windows, fans on max and set air con to recirc. and have a cup of tea. Link to comment Share on other sites More sharing options...
irishejit Posted April 26, 2009 Report Share Posted April 26, 2009 mine only smells for the first min of turning it on... only happened since I had it in gettin a new tensioner fitted?? Link to comment Share on other sites More sharing options...
Sparky Posted April 27, 2009 Report Share Posted April 27, 2009 Supposedly, if you've had your air con on cold for a bit, towards the end of your journey, stick it on warm for a min to let it dry out the condensation, which helps prevent the smells.

whippg Posted April 28, 2009 Author Report Share Posted April 28, 2009 Thanks for all the comments guys, but I'm still struggling to find this air intake. I set the climate control to Re-circulate + Econ + Top Vents Only + Max Fan Had a good look in the passenger footwell and even used a lighted cigarette to check for signs of smoke drawing. I found a couple of likely areas but neither appeared to draw air / smoke in. 1 - In the passenger footwell, under the glovebox, at the back, on the side of the centre tunnel there are 3 rectangular 2cm x 1.5cm holes side by side 2 - Again in the passenger footwell, in the centre of the underside of the glovebox itself, there is a single 3cm x 2cm opening. There are a couple of reasons why I'm reluctant to just spray the Airco Fresh in the footwell itself First off it's quite a wet gas and will obviously make a mess of the carpets and trim, Secondly an aircon engineer who looked at a previous car said that it works best the nearer you can spray it to the 'evaporator' - hence by inserting the tube into the air intake itself I stand more chance of 'hitting the target'. Unless any of you can help me track it down, I may have to call Audi. Link to comment Share on other sites More sharing options...
maersk Posted April 28, 2009 Report Share Posted April 28, 2009 If you leave it on all the time (as designed) you don't get this.............................................................................. Link to comment Share on other sites More sharing options...
whippg Posted April 29, 2009 Author Report Share Posted April 29, 2009 Maersk - I do leave it on all the time as designed. It's the previous owner that needed your pearl of wisdom Link to comment Share on other sites More sharing options...
MattS3 Posted April 29, 2009 Report Share Posted April 29, 2009 Mine used to smell, but I did leave it on constantly, and within a week or 2, the smell went. That was 16 months ago, and I haven't had it smelly since I've left it switched on. I also tried a cleaner/air purifier and it didn't work.

UBM Posted May 8, 2009 Report Share Posted May 8, 2009 So, does it still pong? Mine pongs for a few weeks at this time of year - it is the rape seed pollen from the fields. Should clear up again soon (after having my aircon services last year!) Link to comment Share on other sites More sharing options...
cruiser647 Posted May 8, 2009 Report Share Posted May 8, 2009 I was always told that you should turn the air con off a few miles from home. That way it doesn't leave any moisture/condensatin on any surfaces for bacteria to congregate on and so start smelling. I do not leave the aircon/climate on all the time and I have never had smelly air con. I do make sure I use it about once a month in winter though.

geddy Posted May 9, 2009 Report Share Posted May 9, 2009 the bad smells that you getting is bacteria on the condenser unit behind the dash Link to comment Share on other sites More sharing options...
MikeA2B Posted May 9, 2009 Report Share Posted May 9, 2009 Hi guys, I have had the smelly air con problem for years and tried all sorts of products to fix it, The one product that worked for me was this stuff -----> Deodorising/Sanitizer, A/C AC Air Con Conditioning on eBay, also, Air Conditioning Tools, Garage Equipment Tools, Cars, Parts Vehicles (end time 03-Jun-09 21:54:34 BST) This is how I did it: Buy a tin of airco-breeze and a replacement pollen filter. Start your car and switch the air con / climate on Adjust the fan speed to the lowest setting and open dash vents (this ensures the internal flaps are open and allows air flow) Spray the airco-breeze in each dash vent for 10 seconds. adjust aircon / climate to max cold setting & switch on recirculate, make sure all windows and doors are closed and leave running for 10-15 minuites. After this switch the car off. Then open the bonnet and remove the pollen filter Mine was located under the plastic batter cover on the passenger side of the car (A4-B6) Once you have removed the pollen filter spray some Airco-Breeze into the pollen filter intake for about 10 seconds. The start the car and switch on the aircon, switch off recirculate, this will open a flap below the pollen flter intake. Spray some more Airco-Breeze into the intake for about 10-15 seconds. Leave the car running for 10 mins with the windows open. Then you're done! I hope this helps. Link to comment Share on other sites More sharing options...
whippg Posted May 11, 2009 Author Report Share Posted May 11, 2009 The smell has subsided a bit over the last week or so for some reason - (I always have the air con on all the time so that's not a factor). However I reckon it's still worth giving it a spring clean so I'll give Mike's advice a go (thanks Mike) and see if that gets rid of it completely. Cheers for all the comments folks.

whippg Posted June 9, 2009 Author Report Share Posted June 9, 2009 Finally sorted out my stinky aircon. Followed MikeA2B's instructions and sprayed Airco Fresh into each vent (glad it comes with a useful long spray tube) Next I removed the cabin air / pollen filter from within the engine bay - this was so easy even someone like me who knows diddly squat about fixing cars could do it. All I had to do was pull off the cover to the right of the battery (standing in front of the car facing the engine), unclip then pull out the filter cover, and pop out the old filter. Gave it a good few blasts into the open intake and let it dry out for an hour. Slapped in a new filter I'd bought (a very reasonable £11 from Audi) and jobs-a-goodun. No more stinky aircon. Hoooooorah Thanks to all of you for you comments - especially MikeA2B for the detailed instructions. Link to comment Share on other sites More sharing options...
