07 focus c max. one of the gutter cover trim is missing. and have water in the boot. would there be any connection?. have read that when I replace the cover trim, to put some sealant under it. would this be necessary.  thanks for any help  

Hi. The gutter rails have been mentioned before for possible leaking points along with rear lights and hinge mounting points. My 2012 Focus was actually leaking through one of the rear quarter body air vents located behind the rear bumper. Its easier to sit a trickling hose pipe on the roof and then wait for the water to start coming in so you can trace it back. My wifes Grande Punto had a leak due to one of the body panel seam seals perishing! It really is time for a bit of investigation work im afraid rather than guessing.

thanks for reply. now I know where to start.

I had water leaking into my boot, and using a watering can, tracked it to the gutter. In warm, dry weather (ha!, might be some time from now!), I firmly shoved a generous amount of silicone sealant up under the gutter, in between gutter & roof. It seems to have stopped it.

I Just have water coming in the front now. I have not managed to track that down yet. It may be the windscreen. Bah.

If you remove the light cluster have a look if its just a foam gasket that creates the seal between the light and the car body. If it is then a good smearing of grease on the gasket will create a seal. I always do that on my cars as it cured a leak in the past for me. You should be able to see on the gasket if water has been getting past it as there will be a slightly dirty residue on it where its been leaking in. I wouldnt use silicone as you need to be able to remove the light unit in future to change bulbs, grease doesnt set so it will not stick the light and car body together.

Not currently. When light, if all is not frozen solid, I will try to get one. I just re-read wot I wrote, and didn't mean gutter, I meant roof rack rail. It was late!

The C-max may be different in design there.

I checked the rear light cluster thoroughly first, it did not seem to be that on mine, but it is a weak spot.

I just use bearing grease but any would do. I apply it quite liberally so it lasts for years.

It is not possible to see the leak point, the fixing is some way up under the rail. I just pushed the nozzle in as far as it would go (where the screwdriver is), and squirted plenty of silicone in there. It seems to have done the job.

It does not look like the area inside that tailgate has been washed recently, or indeed, ever !

That is one dirty car!

thanks for pic for reference Peter never really thought it could leak there

quick update. had rain here last night, covered parcel shelf in kitchen towel, this morning the towel was wet under the iso fix roof belt. the roof felt dry. can the roof bar be easily removed , and replaced with silicone?.
