Gentle Knocking Noise Coming From A Closed Roof
Hi,
I have a gentle knocking noise coming from the roof on the passenger side behind the seat. I have just spent the last hour trying to find out where the noise is coming from but no result. I have had the rear springs replaced so I know its not them. The noise only happens when the roof is up. The knocking noise is like something is swinging back and forth when the car goes over bumpy ground (20-30mph or less).
Anybody have any ideas as its driving me around the bend.... Thanks

Re: Gentle Knocking Noise Coming From A Closed Roof
Is the tray under the roof stash space firmly locked in the down position?

If toast always lands jam side down, and a cat always lands on its feet, what happens when you strap a piece of toast, jam side up, to the back of a cat?

Re: Gentle Knocking Noise Coming From A Closed Roof
I've had a good look around the boot and the roof lining and I couldn't see or feel anything loose. It's not a rattle or sqeek noise but more like if someone is gently taping on the side of the roof (it's hard to try and explain really)!

Might have to do that. I was hoping someone might of had the same problem and found a solution?

So here's the obvious question - does it knock with the roof down?thecremeegg wrote: ↑Sun Sep 09, 2018 12:26 am Bump! Was this ever solved? I have the same issue and it's driving me mental!
Yes and its most probably not the roof; no and it is and you've got a very limited set of causes - more likely the roof is amplifying the sound.

Only seems to do it with the roof up and it doesn't seem to be affected by bumps.

The clear plastic wind blockers inside the roll hoops tend to rattle about and you can’t hear them with the roof down. Tiny blob of clear silicone in each corner sorts it.

Hmm I'll have a look at that. It's weird as it sounds like it's coming from the back of the car rather than in the cabin but you never know!
