Rolling Object in Dash - Driving me insane!

[DV8SHN]

Hello AULRO! My first post consists of a request for advice.

First off, a bit of background. My car is a Land Rover Discovery 4 2016 MY 16.5 TDV6 in black. I love it! When I bought it as a demo, it had no navigation in it, but oddly, a NAV button. I consequently had the dealer install a navigation system to clinch the sale. So the NAV system I have is aftermarket, but integrates with the NAV button, and NAV touchscreen button. I just don't see what street I'm on in the home screen like others would, and the maps are slow and clunky. This unit required, I believe, for the dashboard to be disassembled for the navigation module to be installed.

Next, the panel under the steering wheel lightly rattled or vibrated or resonated. I hated the noise so I brought the car to Land Rover to get it fixed up. They have managed to do this well, apparently a couple of the retaining clips were broken. Well, maybe it was the nav installation.

But today, the reason I'm writing this out: there is a rolling sound when I turn corners. It's metallic, like a coin rolling back and forth. Or sounds like a marble on plastic. If I turn the car, brake a little hard, or accelerate hard, I hear it. It is sending me mental!! I have managed to remove the console where the CD storage is all the way up to the touch screen, test drove it, and can't find the damned thing. My ears tell me its behind the upper glovebox.

Should I bring the car to Land Rover knowing full well they'll have to disassemble the whole dash to find this thing? Or should I persist and continue disassembly myself? I am going nuts...seriously.

Thanks everyone!

As your D4 is less than 2 years old I imagine it should still be under warranty, Get LR to sort this out for you.

Ahh, harks back to the "good" old days of the British motor industry in the Sixties. Workers at Rootes would put a nut or nuts into the box sections of the "chassis" so that they'd rattle right through the life of the car and annoy the owner.

It was done to annoy management. Duh?

Check the ashtray for earrings :Rolling:
Sorry couldn`t help my self[bigwhistle]

I had a similar thing with my 2016 D4. It turned out to be the coins in the tray below the radio. Sorry if this sound condesending, it is just that i had the same problem and it took me ages to realise it was this simple. I wish somebody had suggested it to me. My wife and i put up with it for 2 weeks while touring before we stumbled upon it.

Yes! Coins make a hell of a racket in there don’t they. Was thinking of lining the sides of mine

It was done to annoy management. Duh?Oh yes. My uncle bought an Aussie assembled XJ6 in the mid seventies which had a knocking noise in a rear door. It took a long time to find but was a nut on a piece of string with a note saying 'found me at last'.

It’s not just you ... similar noise from glovebox area ... more of a marble clunking against something, like hitting the air con ducts back there ... annoying as ...

reluctant to disassemble the entire glovebox any further as I believe it’s not an easy bolt in/bolt out job....??

Have sheathed many wits and cables in the engine bay/scuttle area - culprits could have been UHF or double battery wiring ... to no avail.

LR had a look a said it was something outside or underneath , but really didn’t fix anything.

Other ideas?

Does the sound last for the whole turn, or just briefly?

Could the object be in the ducts for the windscreen air? Not impossible for someone to have something on the dash and during braking it falls through the slots?? Could find out if the “roll time” is similar to the duct lengths to see if this is a possibility?

DV8SHN, any progress?

Check the door keeper, dont know what its proper name is, but the arm that stops the door from opening too far. On my RR the nylon guide in the door had broken allowing the steel arm to flop around, drove me mad, got under the dash, zip tied everything in sight etc then weeks later, noticed the guide was missing, wrapped the arm in electrical tape, sound gone.

Had another poke around - underneath this time. Looks like there may be a “ball bearing” looking piece of gravel rolling around on the upper side of the engine undertray - no doubt collected from adventures off road! No idea if that’s my noise .... so, is the undertray simple enough to drop, by undoing its fairly obvious bolts?

I highly doubt you’d hear that in the cabin however yes, easy to undo

This one describes mine well. It's near the glovebox, and it sounds like a marble. It rolls a very short distance, let's argue a few centimetres (as I can't see it). I will hear the noise if I turn sharp left, or right, like veering around an animal, or if I turn corners as the turn starts. I sometimes hear it if I brake aggressively, or accelerate aggressively. I think it may be in the vents... grrr.

No coins in ashtray, or earrings ... in fact I had the whole centre console in my house and took it for a short drive. I could still hear it! (For those that did read this far, I had the PRNDS control sitting on the passenger seat).

Ryall I'm going to check that out right now!

As I had had this issue in a 2nd hand vehicle in the past, it was actually the first thing I checked. Sadly, my D4 ashtray/coin holder thing is as shiny as new. Nothin' it it :)
