Morning all.

I've had a tapping noise steadily getting louder and more frequent coming from the rear right cabin area where the roof meets the area above the strut tower and cannot for the life of me find what it is.

I've had the rear of the car apart and can't find anything in the roof assembly, head rest assembly, seat belt mechanism, etc.

The handbrake cables don't rattle when I've jacked the car up either.

The noise is generated over uneven roads, so most of the time here in the UK, and particularly when unloading the car going around right hand corners and roundabouts.

After putting everything back together having had the roof back for a few hours the noise went away for about 2 or 3 miles, but then came back again. Nothing seems loose under the car but it's hard to be sure without a proper lift and shaking the car left to right by hand doesn't seem to recreate it.

Anyone else had a similar tapping sound from the rear corner of the cabin? Only other way to describe it is as if something hard plastic or lightweight metal is tipping left and right, forward and back and creating a tapping noise when the car is jostled.

Cheers!

So, semi success, but not from the soundwave stuff which nearly made me vomit 😂

After taking the wheel off again, removing the wheel arch liner and not finding anything loose I found a video online of someone fixing their noises via lubricating all the ball joints and bushings with silicone spray. It's only a temporary fix if it worked but would highlight that the noise is not a tapping but an intermittent creaking.

Finally I managed to recreate the noise on demand by swerving the car left and right, unloading and loading the chassis further compounding the idea it's bushings or creaking roof.

Anyway to cut a boring story short I tried it out and it's only bloody worked. Absolutely dowsed the rubber bushings and spring seats, subframe mounts, etc in silicone, drove for about 5 to 10 minutes and it's stopped the noise. Made a video - it sounds more like creaking here than tapping because of the swerving to make it happen all the time. Before this it was just the odd tap tap noise, but elongated it sounds like a creak.


Now I'll need to figure out which bushing or rubber component is knackered but for now at least, no bloody noise.
