Abs Posted February 10, 2009 Report Share Posted February 10, 2009 Hello chaps! I seem to have water build up under the black cabin air intake box. This picture describes it better.... (black box to the left of the pic) As per the instructions at the bottom of this page, labelled "Checking the cowl drains"... audipages Unclogging the A8 Evaporator Drains Does anyone know how to unclog this? I can't seem to get any flexible copper piping, and don't have access to compressed air. Anyone have any ideas? Link to comment Share on other sites More sharing options...
sgtstrev Posted February 11, 2009 Report Share Posted February 11, 2009 The Evaporator drains are accesed from the inside of the car by removing the centre console side carpets you will see the rubber orange right angle drains , but i suspect that the wing drains are blocked this is probably what is causing your water build up . If you have a look up under both front wings at the top back corner you should see a rubber drain tube about a 2" inch long with a flared bottom these seem to block on my car very often almost every time i wash the car i seem to be unblocking them . The copper tube i see in your picture looks like it might be about the right size to push up through the rubber drain and clear it . Hope this is of some help to you .

Abs Posted February 11, 2009 Author Report Share Posted February 11, 2009 Hi sgtstrev, thanks for your reply! However, I think you may have mis-understood me. It's not the a/c pipes which are blockes, or the wheel arch drains. If you have a look at the audipages link, it's right at the bottom under "cowl drains". There is another drain situated under the black intake box as shown in the picture above (the black mesh box towards the left). This is the drain which is blocked.

harpersimon Posted February 11, 2009 Report Share Posted February 11, 2009 Correct, and its a buger to get to. You need something flexible, or a tube and some comp. air basically. . and then be lucky (or take the gearbox off, then you can get to them :-) Link to comment Share on other sites More sharing options...
Abs Posted February 11, 2009 Author Report Share Posted February 11, 2009 lol! I was worried you were going to say that! Does anyone know what the "hole" looks like? i.e. if i get something long and flexible, will i be able to fiddle around with it and "poke" it through the hole? Or is it not like that?

GarbitAsh Posted February 12, 2009 Report Share Posted February 12, 2009 I cleared mine successfully from underneath. Much easier than fiddling around under the airbox with tubes and compressed air, which most folks don't have access to. Link to comment Share on other sites More sharing options...

CMJ Posted February 15, 2009 Report Share Posted February 15, 2009 Flexible copper piping avail from B&Q (the type used for radiators at home) Not cheap about £17 for a roll. Follow the instructions posted online and it works a treat. Fill cowl with hose pipe. Poke around and whoosh....out will come all the water. The compressed air bit helps with making sure it is really clear. Link to comment Share on other sites More sharing options...
