There is nothing on the roof, or anyone near the van, it can happen when driving or parked day or night weather makes no difference it is totally random and no matter where you are in the van it sounds like it's on the roof but I left the phone inside recording it and stood on a nearby wall and there was nothing there, most of what you hear I recorded sat behind the steering wheel, you can hear me walking around the van on gravel.

It's getting quite serious as it's happening more at night now and it's frightening Liz so much she's afraid to go back to sleep even though she knows it's the van making the noise and not something outside.

this was recorded in May this year but it's still happening every now and then.

When the noise takes place have the interior lights started flickering at all?

 

[Pudsey Bear]

I don't know, it happens without anything turned on, or even when we're driving.

 

[mariesnowgoose]

How weird.

Poltergeist?

No seriously - is there any way a wee beastie could have snuck in somewhere?
Sounds kind of electrical ... ?

 

[mariesnowgoose]

When the noise is happening have you managed to pinpoint exactly where it's emanating from?

As I say, no matter where you are in the van it sounds overhead, except when in the cab, it sounds to come from the wheel arch but sit on the other side and it sounds like it't from there.

I would disconnect all the Elec Power to the van when the noise occurs, see if it stops , then process of elimination probably by removing Fuses ect.

Have you got a double floor in your van?
As Marie suggests a wee beastie may have snook in and roaming around between the floors

That was the first thing I did well over a year ago I pulled the battery leads, made no difference.

No, no voids anywhere.

How about a solar or satellite cable not clipped down and flapping about on roof in a breeze

 

[Pudsey Bear]

No not that either, I have really looked at everything on the van, we even thought it might be heating up or cooling down, but it can have been raining for a few hours and it kicks off, or been in strong sunlight, it stops and starts, makes no difference, the recording doesn't really help to grasp the volume it is really loud.

Faulty speaker or smoke detector or carbon monoxide detector perhaps?

 

[saxonborg]

I agree with AllanD it sounds like a duff speaker.

No not possible with no batteries connected.


It does sort of sound like a volume or tuning knob which needs switch cleaner though, wish it were that simple.

 

[mariesnowgoose]

Fascinating, frustrating and highly irritating?

 

[Pudsey Bear]

You have no idea.

But a smoke detector for example usually has it’s own (9v) battery to power its alarm “speaker”. Wouldn’t rule any alarm related devices out until you’ve checked all that you may have (sorry, don’t know what you have/haven’t got installed).

 

[Pudsey Bear]

Sorry Allan, I forgot to add that it does have a co2 and smoke alarm and stood next to them when the noise is heard, it's definitely not those.

It's a crow in the background .... but to be serious it does sound like the electrical noise you get from a speaker with a duff connection or speaker. Doesn't sound like any four legged visitor I know, that would be more scratchy ........ or sound of movement and wouldn't it be dead by now
