MattS3 Posted September 8, 2007 Report Share Posted September 8, 2007 Looks like I may have a small problem with my S4 already........although its not stopping me from smiling yet ! Had the air con on all day today and its been smelling a little niffy when I switch to the Econ mode. and this evening I seem to have water dripping from the passenger side, underneath the glovebox. Its still heating and cooling ok so I dont think it can be the heater matrix, is it possible that I have a loose hose somewhere behind the glovebox? Will take a look in the morning, but need to know how easy the glovebox comes out? Other than that, the car is awesome. Mid range grunt is soooo much smoother then the re-mapped S3 I had Link to comment Share on other sites More sharing options...
PetrolDave Posted September 9, 2007 Report Share Posted September 9, 2007 Sounds like the evaporator drain pipe is blocked. When the air con is on condensation happens on the evaporator and this should drip out underneath the car, but if that pipe is blocked (by dirt etc.) then the condensation finds the next easiest way out - down one of the heater outlets, which in your case is into the passenger footwell.

MattS3 Posted September 9, 2007 Author Report Share Posted September 9, 2007 Just posted this reply on Audi Sport before coming here..... Just had the glove box out, and that was very straight forward. looks like the water could be coming from the re cir unit/fan, but typically, it isn't doing it now. Interestingly though, there seems to be no water coming from underneath the car when the air con is on which may suggest the drain hole for the air con is blocked. The water which is coming out, is clean, which would back up this theory. I dont know where the drain hole is to unblock it though looks like you could be spot on Dave, any idea how i unblock it?

[/ QUOTE ] Get the car up on some ramps and look for a rubber hose with a flattened end in the area underneath the heater matrix/evaporator. In my experience what happens is that the flattened end gets "glued together" by leaf residue, tar spray, etc. - so once you've identified the hose just try pushing a screwdriver up it - but make sure you are not underneath it!!!

MattS3 Posted September 9, 2007 Author Report Share Posted September 9, 2007 Excellent, will do. Cheers Link to comment Share on other sites More sharing options...
MattS3 Posted September 10, 2007 Author Report Share Posted September 10, 2007 Think I've sorted it............its coming in thru the pollen filter under the bonnet. When I wash the car, it must get in then. Have cleaned the leaves out and re seated it, hopefully it will fix it. Link to comment Share on other sites More sharing options...
kite Posted September 11, 2007 Report Share Posted September 11, 2007 There are drains under the car battery as well, these have been known to block, could be worth clearing these as well. Have a look in the passat forum for a how to Link to comment Share on other sites More sharing options...
MattS3 Posted September 12, 2007 Author Report Share Posted September 12, 2007 Right, final post on this, but thought it may help someone else who may find themselves in the same position....... After having the Millteks fitted today (oh man, how good do they sound !!!! )I took the mechanic for a ride up the road to experience the car. Whilst doin it, water appeared near the footwell again. Stripped the polen filter, no water there so must be the air con drain pipe causing the issue as still no water draining under the car. They kindly let me use their tools to take my glovebox, trim and carpet up a little and then I found the flat pipe near the transmission tunnel. Disconnected this and water flowed over my hands........result, the ignition was off which meant it must have been backed up. Gentle squirt with the airline, reconnected it, turned it on and the water flowed freely No more blockage, no more leak. As Pete said at the start, it must have been flowing out the nearest vent. Job done. And the exhaust has made my day ! Link to comment Share on other sites More sharing options...
