I just fixed the door cards. Noises are eliminated gradualy in my 4.5 years old combi.

Next one, very irritating too, it somewhere in the pillar, ceiling, door-againt pillar or ceiling. It's like a plastic hitting against plastic somewhere from the inside. Like a cable or so. I cannot identify it. I positioned my chair up in the air now and maybe I can detect it better.

I even opened the pillar where the seatbelt is fixed but there everything is clean.

It's not the seatbelt mounting either ... soft noise but present always on bad roads.

Did you guys have problems with noises in the ceiling or back doors? Another place it could be comming from is the ceiling lamp. It sounds like a loose cable in the ceiling edge or something ....

After some more investigations I think that the problem is not particulary in one place. Because of cold temperatures the plastics hardened a bit and they make these creaky sounds. In some places I observed that dash board grease like silycone helps.

Especialy the gum seals arround the doors openings make that hard unglued sound. I tested the same material on a new fabia and it's quiet, maybe it comes from aging or because the trim plastics are slightly greased when they come out of the production line.

Still not found the noise.

Mine is a combi so it has ceiling lamps in the back near the roof handles and rail roofs.

The noise comes from up backwards likely in the roof somewhere.

These are the list of what I have checked so far:

- pillars (between doors) dismantled

- seatbelts mountings

- door seals

- ceiling lamps, cables come from the back, seem not to rattle

- front roof handles

- rear seats (fixed already) but anyhow

It seems to me that all the ceiling is creaky and unfixed. It is not clipsed nor screwed besides the roof handles and door seals. But these should hold it in place quite good.

What else could be? Cables in the roof? Water lines for the rear screen washer? Rear doors not closed properly and rubbing against something (not likely)?

When real cold weather there are no noises -10deg, when -2 deg i get the sound on bad roads when the car shakes from left to right especialy.

Any help it would be very apreciated since this gets on my nerves. Never before had I encounter noise in a car that after so long I could not locate and fix ...

I know you mentioned you had already done the rear seats but have you:

a) siliconed lubricated the mountings and catches (where it clips in when you fold them down) for the rear seats; and

siliconed lubricated the parcel shelf mountings.

These both made a difference on my Octy but not sure if its the same on a Fabia.

BTW - Sumo fan by any chance?

Yes, I like sumo a lot .

I have lubricated the rear seats mountings and catches as you said.

I have also made small bushes for the roller. I have a roller for the trunk because it's a combi.

I also have railroofs on mine. Maybe the railroofs move on the top of the car ( bushings ) while on bad roads and that noise transmits through the roof making it horrible to pinpoint it. Did you have similar problems like this?

Sorry, I don't have the rails on mine so can't help - seems a sensible thing to check though. Good luck

Thanks. I hope I will fix this somehow. Now it's too cold to do serious investigation, but I have been trying this and that for almost 1 month now.

I have tryied something else. I have isolated the metal ear on the door pillar that the door hangs itself when closed and unscrewed a bit the door bushings. Now the door si more rigid when closed. The noise has changed a bit ... i think it is related to the door. Maybe something inside the door card moves or the door pressing on the rubber seals.

Also something else I've noticed, the rear arch trims (those that sit on the rubber door seals and go underneath the seats) make a crazy creaking sound ...

Another thing got to my attention.

Did anyone have any rattles with the cable tree housings for the doors? Especialy with the rear cable tree, that is mounted on the outside of the pillar (between the doors and goes into the back door). It seems to me that the mounting is a little loose.

I think I got to the bottom of this problem after a long time of investigations.

It seems that the door seals were causing the problems. Realy hard to diagnose this. Before the cold period came I lubricated the seals with some glycerin to prevent the doors freezing on the seals (which I had plenty of hard times last years). Until recently I did not know it were the seals so I investigated a lot of sources.

I found out from a similar problem in octavia 1 from the german forum. So I cleaned the seals with window-wash solution. I removed the glycerin(partialy) removed partialy the seals from the door and cleaned the dust underneath them and on them. Now they seem to be quiet. Perhaps now I will have the problem again with the freezing seals. I hear that the BMW gummi-pfelge works wonders on the seals of bimmers and vortexers.

I realy hope the problem is fixed now because I drove me nuts.
