well i've had a good look at the heater unit (lying upside down in the footwell with an inspection lamp!) and i can't see any signs of moisure on it/dripping off it or any signs of rust runs. i've noticed that underneath the car, under the passenger footwell, there is a plastic 'drain plug' missing (there is a hole approx. 40mm in diameter which would normally have a plastic blank in it- like the hole next to it). I am wondering if this could be the cause. I shall keep trying to find where the moisure is comming from

Hmmmm heater matrix.... is it a bugger to replace? and are they expensive? I bet its right inside the dash and you have to take the whole thing apart to get to it... i will investigate. Do you think it is worth trying to block the leak (if it is the matrix that is) with something like Kalimex? I'll keep my eye on it and see if the carpet drys out after a period of no rain and not washing the car. This will help pinpoint whether it is an external or internal leak. thanks

1996 1.0 ax debut 90,000miles hi i have noticed that the carpet is wet in the front passenger foot well recently i topped the coolant up. if the coolant was leaking, would it be possible to get into the front passengers foot well (drivers side seems dry)? or is it likely to be rain/car washing leaking in? and if so are there any places that are prone to leaking in and around this area? and any advice on sorting it? thanks in anticipation.

thanks for that ronin. i took it to the garage in the end (before i got your post as i didn't realise it was so simple) i told the mechanic that i had heard that citroen engines are known for problems with getting air in the coolant system and could he just bleed it and see what effect it had. He said he wasn't aware of such a problem but would do it anyway. he charged me £20 and the the overheating light hasn't come back on since and the fan is no longer on at the end of every journey so it must have worked! :) thanks for your coments

Citroen ax 1996 1.0 dimention. 75K miles. When I start the car I can hear a gurgling sound and the sound of running water...it sounds like its comming from under the pedels. I'm sure its done this for quite sometime- at least 6months. Recently the overheating light has been comming on- strangely it goes off if you drive the car fast/hard! The fan is on a lot too (pretty much everytime I stop the car, the cooling fan is on). Someone has suggested that it may need bleeding. does this sound like the case? if so, how exactly would I go about doing this? If not, what else may it be? Coolant level seems constant so don't think its loosing coolant. heating still works. many thanks in anticipation
