I thought it was in the back of the headliner, or potentially in the sunroof cover on the inside.....but no, it was the sunroof motor/support that was knocking on the roof when going over bumps.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I've had a knocking in the headliner since I bought the car when going over bumps. Very annoying. I thought it was in the back of the headliner, or potentially in the sunroof cover on the inside.....but no, it was the sunroof motor/support that was knocking on the roof when going over bumps. I didn't take any pictures, but here is what lead me to that conclusion: Going over bumps, if I put pressure on the cover for the dome light near the aft portion of it, it would silence the noise. The area just forward of the sunroof. To remove the cover, just pop the two black covers, take two Phillips head screws out, then unclip the rear end with a trim removal tool (will pop out) and then slide forward towards the windshield to unclip the front end. You'll see the sunroof motor, and then I could just push on it and something wasn't right, it would flex and bump the steel roof, causing the noise. I cut hockey tape about 30" long, then folded it over on itself a few times until I had a piece about 4" long. I did not fold it perfectly so some of the sticky would still be on the outside. Shoved about 6 or 7 pieces like this under the motor and the supports on the driver's side.....and this stopped the noise. At least $1 worth of hockey tape. These cars are expensive! Hope this helps somebody.

thing...I figured I would need to pay someone to drop the whole headliner to see what is what. Will definitely give this a shot first.

POST 3 / ORIGINAL POSTEROriginal post

bac2h: Once you remove the light assembly, there are also two screws for the headliner adjacent to the sunroof panel that if you remove it's a little easier to get to the motor by more deflection of the headliner....the whole process took me 20 minutes. How the heck do you edit the title of a post?

Took a look last night and felt no play in the motor. .must be something else. .
