The drivers side front drain tube does not drain but the left side does.
Resulitng in water overflowing onto the headliner running down the inside the A-Pillar upper and lower onto the carpet.
I have tried unblocking the tube with a small stainless coil and can get 110cm down the tube but no further.
On the left free draining tube I can still only get the coil down to 110cm also so I imagine there is some connection or bend at that point.

Does anyone know what happens beyond that point wher the blockage might be?
I am thinking that the tube may be bent or trapped somewhere.

I have in the past removed the wheel arch liners to check the the bulkhead drain plugs have been removed allowing them to drain freely.
I didn't notice another drain tube that might be the sunrroof tube exit.

Someone did suggest to me that the sunroof drain tube ends inside the bulkhead and isn't visible?
