Diagnosis #8 – Soggy Feet

Meet Oscar – The 2009 ’09’ Citroen C1

Oscar

With a weird and completely random problem of the passenger floor becoming wet. It didn’t always become wet when it rained, sometimes it will remain perfectly dry, sometimes slightly damp.

Its had the upper half of the door seal packed before, as there was evidence that water was slowly dripping from up above. However this has remained dry indicating there was now another way the water was getting in.
This was quiet an detection, throwing a little bit of water over the vehicles passenger door while it was raining, it became clear there door seal was remaining dry where it should and wet where it should, except for 1 random place on the lower part of the door

Over the seal
and onto the floor (you can see a faint darker patch as it branches into 2 paths)

So the next task was to pack the door seal with a narrow 3mm poly tubing, this would mean as the door closes it’ll clamp the doors seal tighter onto the door – hopefully preventing the water getting into the vehicle.

By the looks of it, when manufactured they simply produce a massive length of the door seal, cut to length and stick it together. Which meant in the middle of the door there is the join, meaning i have todo 2 runs instead of the 1

Luckily since the seal has numerous vent holes to prevent the seal going bang when you shut the door due to the trapping air, i picked 2 holes to feed the tubes

Since the tube was cut to length, its an invisible repair and hides perfectly inside the door seal.

With the door sealing tighter against the seal and frame, the car should remain dry on the passenger side once more!
