Sunroof Drain Tube won't unblock!
Hi all, asking more out of hope than expectation.
Had loads of problems with the sunroof on my 146, I've changed the roof itself.
I've checked both ends and it looks like the one way valves at the bottom has been removed.
The front drivers drain tube is blocked about 3/4ers of the way down- I've tried curtain wire, a drain unblocker and filling it with water and using a tyre compressor as an airline but the blockage is still there.
I've tried bicarbonate of soda to clear it and this hasn't helped.
My best guess is that this is a piece of rust from the old sunroof that is lodged in the drain tube.
Beyond trying a higher pressure airline (which I don't have) does anyone have any suggestions of what else I could try, a dry drivers footwell would be nice!
Thanks in advance for any help!
