Folks, I've had a rattle from the rear for the last few months which I assumed was caused by the boot. I spent the last few weeks adjusting the rubber bump stops but to no avail. Then at the weekend I opened the sunroof a little and the noise stopped. Sure enough, each time I have been driving it since and opened the sunroof the noise stopped immediately.

So its a rattle that sounds more like a click or tick- hard to describe exactly but it occurs when going over bumps!

Anyone ever had anything similar? Any idea where to look to try to sort it!? It stops as soon I open the sunroof, but I've literally no idea where to look and how to fix it!

Have you searched the terms unroof on the forum. There have been loads of posts over the years. Mainly about leaks but there may be info there that helps. A new cassette is very expensive so hopefully it will be a simple fix....

Yes, had already searched on here but to no avail.

However I just searched on google too and it seems to be pretty common. I'll have a go when I get home tomorrow;

It may be that because the usual rear sunroof problem is that it jams and has to be disabled, or it fails and has to have a new cassette fitted at around £2k
