An occasional knocking noise has started and I just can't work out what's causing it.
It's intermittent.
Not connected to engine speed.
Usually follows road speed (but not always ).
Can only be heard at low speed.
Appears to be coming from the roof or high up on the sides.
It sounds like something slapping the roof in the wind, but I've been up there and there's nothing loose or extra. The pop-top clips are all secure and there's nothing in the fishpond (it's a Holdsworth).

I know it's next to impossible to diagnose something like this without seeing it, but if anyone has any, ANY, even the vaguest of ideas what it could be, I would appreciate it.

IT'S MESSING WITH ME MELON, MAN!!!

Does it sound like a metal ball banging round in a sauce pan

yes it does.... ....does ur's sound like that FP?

No, it sounds like someone has fallen asleep on the roof and woken up as I've started to drive off and they're trying to attract my attention by slapping the top of the van.

^^^^.. thats a better description...maybe hitting the side of the van with a pan

mrs iguanas holdsworth popper has more knocks n rattles from up top than a knocky rattley thing.....never managed to find the fault so she just turns the stereo up even louder(if thats humanly possible!!)and ignores it......me being a mechanic ,i end up sitting in the back jumping around like a pillock tryin to find every bump n squeak....

You haven't got an ariel that flaps around in the wind and hits the roof?

no we aint got that...all the flappy bits outside are tight..our's almost sounds like summit rollin about and hittin the sides...but there is nowt on the inside rollin about....maybe us and FP have a goolie ghost on board

No, the aerial is rusted shut.

There's nothing loose, as far as I can tell, and nothing to flat about. But that's what it sounds like. It just started a couple of days ago and it's been doing my head in ever since. If I had any hair, I'd be pulling it out.

I've got to pay more attention to details.

I think I found my flappy thing.

The plasticky trim thing between the roof and poptop base has come loose.

I can't push it back on as it's under way too much tension (I guess that's why it managed to come off in the first place), So I suppose I will have to cut it and fill the gap with something.

Oh well problem solved. It wasn't a ghost after all.

have you looked at the exhaust? mine makes a similar noise and it's the exhaust that's loose

Have had same small problemette on my Holdsworth poptop...so wait till its a nice warm/sunny day...could be some distance away...cut the strip dead centre (relieves any tension) and put each side on using:

1 Warmth of sun making it flexible(or other heat source)
2 Flat blade to assist
3 Lubricant of some sort...KY's good it will wash off in time!
4 Patience...its a fiddly son-of-a-bitch job

By the way anybody know where you can get a new strip...I'm getting fed up putting it back on!!!
