Did you actually solve this? Saw your post in the "What did you do to your Emira" thread where you posted "So today I finally got the headliner to stop making noise after 400 miles.."
Please tell me you found the answer...
Let me drive it a few more day to make sure.. Probably next week..I had kidney stones today and in ER..
But I do know what is causing the noise... If you look at headliner across the rear window there is No Support..
If you push up on headliner in rear about center you may find the noise you hear..
So yesterday I put the double sticky tape all the way across the rear window to get it to stick to window and headliner
so that it is not flexing..I will purchase this next few days from Amazon and just see how this sticks to rear window and
the rubber holding the headliner to make a inside corner ..
What I maybe should have done is pull rubber to headliner and just sprayed foam between headliner and roof and
problem solved...Just was afraid of mess with foam getting on interior...
Hope this helps in your finding your issue ?
So this next whole week I will not be able to do anything because weather is damp and cold here
and none of these adhesives really stick in conditions..
I have Tinitus really bad and yesterdays ride of 40 miles of Quiet was the best ride in Emira of putting total 400 miles on it.
