I note there are references to this issue in past posts but now experiencing this issue myself I wondered if anybody ever identified what was vibrating at this point in the rev range. It sounds like it's coming from under the car at the rear of the cabin and is quite a 'tinny' sound and only at around 1900rpm. -----------------------------------------------

normally and hopefully its just an exhaust heatshield rattling.. ... - .- -.

As Stan says it's usually a metal heatshield mounting bracket underneath the gearbox that gives a tinny rattle.

My 2016 car has a 'resonance' at 1030-1500 ish rpm with a sound that is like someone blowing across a bottle top.

I checked underneath and my car doesn't have the metal bracket on the gearbox or the heatshield attached to it.

Instead it has a huge metal bash plate covering it all.

I'd imagine a 2020 model is the same and just has the big bash plate.

A 2016 model may well be different but my 2013 car also has a bash plate under the gearbox. The heatshield and its mounting bracket is above that. I had to remove the plate when I investigated/fixed the fractured gearbox heatshield so I wouldn't rule out your car having one.

I had a virbration with the gearbox heatshield (above the bash plate). Nothing was visibly bent so I used some self-adhesive velcro (the fluffy bit) to line the underside of the bracket and isolate the metal to metal interface between the bracket and heatsheild. It is now silent. Kev

Kev, I did exactly the same with mine but unfortunately it didn't cure the noise/vibration. I removed the heatshield again, cleaned it up and discovered a crack round one of the bolt holes. So a new heat shield required.

Update

It was a faulty silencer, the insides were vibrating. Replaced under warranty. -----------------------------------------------

Bit of a thread resurrection, but added to help others who find the thread. my rattle has come from the black cross bracket that cradles the gearbox and to which the smaller heatshield attaches to … I’m seeing if a pal can reweld it. It’s one heck of a split though … not something I would expect to happen.

Same here
Anyone had a dealer do it? What should I ask for?
I have them but they say they don’t hear it !

I have the same snaring or tinny sound at 1500-2000 rpm, sometimes louder, sometimes less. Mostly when accelerating or decelerating.

It started at appr. 20k kms.

I asked my son to pass by the dealer who said I drove over something that scratched a wishbone and an exhaust shield and they kind of bent it back again.

I looked under the car today as good as I can but did not see any scratch whatsoever.

But I noticed that the heat shields between the rear mufflers and the body were a bit loose.

Maybe this is the reason, I need to look deeper into this.

You couldn’t see the crack on mine until you had the heat shield off and were taking the frame off. For me, it was a case of just pulling and pushing at parts as I disassembled the underside shields till I found the problem.

My initial thoughts were that it was just a loose shield, so would stick some foam or felt type material between the bouncing surfaces as suggested above. V8 or else ...

:!:

Please bear in mind, do not use combustible material as padding anywhere near the exhausts, particularly with the DPF-equipped vehicles.
During active regen, exhaust temperatures can easily reach 650 deg.C, that’s as hot as a blowtorch! :shock:
