Xantia Mk2: Roof vibrates

Post by marsalek »

Dear guys,

on my Mk2 Xantia Break the roof vibrates in a specific RPM range. The roof is probably glued to a carrier leading between the B-columns and the bonding does not hold any more. When a rear passenger supports the roof, the vibrations are gone.

Is it a typical illness of Mk2 Xantias?
As the interior lining on the roof is glued as well, it is nearly impossible to reach the roof.

Any ideas how to repair that?

Thanks a lot in advance
Karel

I wouldn't say its a typical problem - in fact I've never heard of a vibrating roof on a Xantia!

Hi Marsalek,

I know the noise that you mention, sounds like wires rattling in the roof somewhere on the lefthand side at the rear at certain RPM. Tend to notice it in the colder weather but apart from slight irritation I don't think that there is any problem with functionality.

Would a little shot of building expanding foam above the roof lining cure it?

If it can happen it will.

I think there is only one cure, to carefully un-bond the roof lining then apply polyurethane sealant to the transverse frame members. Re-bond the roof lining afterwards.

My roof lining will need to come out for the side repair, I am actually looking forward to adding more soundproofing.

Hi guys,
yesterday I was able to squeeze some 4 mm thin sponge sheet (5 x 10 cm) in between the transverse frame and the roof. To do that, I removed the rear-passenger handles and cautiously pulled away but not un-bonded the roof lining. Then I moved the sponges towards the middle of the roof by just a couple of centimeters. Now the vibrations are gone, but let's see, for how long :-)
