Water leaking into the rear footwells and underneath the rear seats.
Loved this car from day one for its air-conditioning, comfort, performance, reliability, good looks and boot space.
But now it may be a divorce: for the past 3-4 months I have noticed water seeping into the foot wells and beneath the rear seats.
Citroen said rear door (boot) membrane needed replacing - have charged me £130 for the privilege despite fact that this must be a design fault. Offered to clean and dry the carpets for another £240! I'm still not sure the fault is fixed. This could be the end of my affair with Citroen!
I want to know where is your car made?
Had the same problem with leaks in my 1997 SX auto estate.
However, a membrane was replaced 12 months ago. Now problem free. You can dry it out with lots of newspapers in a few weeks. 144,000 miles and still going strong. A C5 looks like my next car.
I used to be a citroen technician and know about the rear footwells filling up with rainwater. the problem is caused by people damaging the membrane in the tailgate. the water comes in goes under the boot carpet and into rear footwells. a new membrane and elongated holes in tailgate will cure fault.
