Water traced to coming in through upper rear corner pillar, ending up in the boot and rear passenger footwell. Thought it was the wiring loom as a dodgy repair had been completed previously. Replaced, still leaked. Next the Arial as a small amount of water was getting through. Replaced, still leaked. Thought it may have still been the wiring loom so sealed the joint with guttering sealant as a test. Still leaked! Water...gravity....i know how it works!....in a last ditch attempt removed the plastic roof rail....turns out slight corrosion on the rear joint hidden by the rail. Temp fixed with guttering sealant.....now dry as a bone! The attached picture is taken looking towards the rear looking at the corroded joint with the roof rail removed.

Could you please add a 2nd pic.. just a little further away..

Pretty sure its a clssh betwren phone and forum software

Some phones put everything 'upside down'


Thanks for the extra pics

How do you get those “rails” out? My car has slight corrosion at the very back end where the water runs out down under the rear hatch it be very interested to look underneath & try a bit of prevention

i second this, it would be interesting to know indeed!

Well who would have thought it. That’s another bit of info in the arsenal. Thanks for letting us know.

The rails are stuck to the roof using some sort of grey compound, there are no fixings as such. I just prised them off very gently from the rear. You end up with some compound on the rail and some on the car, so it doesn't come clean if you like and need to tidy up before sticking back on. Like I said, it was a last resort for me.

Yeah I’ll be doing that then! I can imagine it was very hard to prise them out I worry about bending them trying to release then getting them back in would be harder
Saying that I’m dying to get in there and see what corrosion it’s going on!

Not a Fiat I know, but the Honda Jazz is very well known for leaking seams in exactly the same area. https://www.youtube.com/watch?v=t8Onmedfmv0

Probably a job for warmer weather..


Rubber and plastic isnt very bendy in a UK winter

and sealant doesn't stick so well either.

A tad warmer today so I prised mine off cleaned the area dyed the plastic strips back black and stuck them back down! A bit of corrosion but mainly paint loss so not too much to worry over
May need doing again one day but not sure what I’d treat the area with!?

Hammerite, thought the body was galvanised?

Perhaps something like this with it not being in a visible area
Should offer plenty of protection long term
Just mask of the paint around the area for any overspray
