Water in floor?

[Ale]

Hi,

My 406 exec has water (or at least I think it's water) under front passenger seat, can hear it after I break before traffic lights etc.

Car is in almost new condition as I don't drive it that much and was wondering if someone had this problem before + what might be causing it?

Thanks.

check your door seels and if you have one your sun roof seels as well.It is more than likely that your heater matrix has sprung a leak though

is it under warranty?

Check all your seals and esp the sunroof if it has one, my husband had a simular prob with his 405 x
