Problems in your Grenadier

[emax]

My first problem since receiving my Grenadier last Friday:

engine vibration felt through the steering wheel; mainly at idle (800rpm) especially in D, a little less when select N but, also engine/cabin vibration on strongish acceleration just at the point of each gear change (to a higher gear).

Took car to nearest agent (mine is further away) and the technician agreed it was a bit too much vibration but not very bad!

He said it could be engine mounts over tighened when the transfer cases were swapped earlier this year. My agent will lift car & inspect when I take it back soon to get the camp table.

Also agent advised that the software update is very soon - maybe 2 weeks and certainly in September.

My workshop contact at the dealership told me that the heat deflectors directly above the rear silencer tend to cause vibrations. These are two such plates formed into a 3D surface that lie directly on top of each other but are not connected to each other.

By the way, I'm talking about diesel.

So if you look at your car from behind, on the right side just above the muffler, you will see the two panels close together and if you snap your fingers against them (be careful, they are sharp!) you can see and feel that this could be a cause of noticeable vibrations.

You have to get on your knees to see these panels, they are somewhat hidden and made of aluminum. He recommended that I take a pair of pliers and bend both plates up and back firmly to suppress the vibrations.

But I didn't do it because I'm going to get an appointment with the agent anyway and have him do this hack.

Ich habe bemerkt, dass sich im Bereich der vorderen Stoßstange links unter dem Kühlergrill etwas verschoben zu haben scheint. Ich werde meinen Verkäufer vor dem Software-Update zur Inspektion informieren. Hat noch jemand dieses Phänomen entdeckt? Leider ist es auf dem Foto nicht so einfach zu sehen, aber der untere Teil stürzt sich nach oben. Grüße Barney.

Thanks Barney - will check mine in the morning.

Thanks emax.

I will look at this today.

However, I keep going back to the engine.

As I said my wife had a BMW X5 and I recall putting my hand on the top of the engine (plastic cover) and there was very little vibration compared to the Grenadier - why if same diesel engine?

Check the difference in idle rpm.
I know the Grenadier B57 is tuned completely different to the same engine in the BMW

Noted but, as I said to the INEOS agent yesterday, siting in stationary a brand new A$130,000 car and feeling lots of engine vibration through the steering wheel is probably not acceptable.

Definately acceptable (expected) in a 30yo Hilux with 400,000km on the clock.

Might be stiffer engine mounts in the Gren, they will transmit the engine vibration right throughout the car.

Head tech guy at agent said INEOS may have over torqued engine mounts when they swapped in the new transfer case but why would the engine need to be dropped or moved for that.?

The transfer case has mounts to the frame so maybe that's what he was referring to and that then impacts engine vibration??!!

Faulty/Low Quality injectors in diesels can be a root cause for engine vibration - I would be checking these with IA... It is a little concerning the number of owners who have reported this problem and no known reason why or fix? Or is it just how the GREN is designed and like others said, tuned?

I have dealt with poor quality injectors once before, and replacement it was the solution I found for my old 3.0D-T Ranger Engine. Thankfully a friend was a high-end diesel mech and knew what was going on!

I own a diesel grenadier and a 2022 530d x drive. i had them both hood up, side by side earlier and I could not detect any difference in the vibration when resting my hand on the top of the engine covers.

when driving, the grenadier sounds much “ beefier” than the 530d both inside and outside the cabin. At road speed, wind noise is what gets noticed but that’s to be expected from a vehicle with the aerodynamics of a house brick. Mine Gren is a December 22 build for reference.
i‘ve said before that I describe the Grenadier as a cross between a bmw 5 series and a Unimog..

Thanks for that feedback.

Vibration being similar at engine means the engine vibration on my Grenadier is being "transferred" through to the cab and the steering wheel somehow (but not on the BMW). Points again to engine mount over torquing

My truck “lost “ the driver’s door today.
I tried to move it and it kept popping into neutral. After 6500 grenadier miles I instinctively opened and slammed the door. No different.
I plugged in my seatbelt and it was happy to let me move.
Having moved the car I got out and went to lock it. It wouldn’t lock.
Also the radio stayed on.
I tried manually locking the door with the key. The other doors remained open.
I rang Grange Edinburgh who were great and gave me another car while they looked at it. On the journey over the seatbelt warning light was on for all seats, but no alarm thankfully.
When I collected later they had diagnosed a faulty door lock. They have ordered a new one. For now I have to lock the car using the button on the driver’s door and then lock the driver’s door with the key.
I remember saying in a thread ages ago that having things like the locks connected to the canbus system would be an issue and sure enough it is! I’m getting odd symptoms like the seatbelt thing and a “ car is ready to drive “ message every time I stop at the lights.
Hopefully some clever chap will come up with an aftermarket software upgrade that deletes all this crap.

Nearly every European manufacturer has used CANBUS signals for upwards of 20 years on their vehicles now, it is the standard.

Deleting the door lock mechanism through software won't solve any of these issues; another easy bypass (and to shut off the seat belt warnings) is to simply turn on off-road mode

Off road mode switches itself off above 40mph. So not much use.
I have had other cars which would lock 3 doors if one was faulty. The grenny wont lock any at all.

Off road mode also changes the ESC settings so probably not good to use it on-road

If it won't go into gear because it sees the door open, having slightly less active stability control is a minor price to pay IMO

 

[Tom D]

It’s interesting how a door fault can cause so many other symptoms. When driving all the seatbelt indicators are red. When you stop the rear ones stay red but the front ones go gray
The start stop system won’t turn off.
When you stop and start the car bongs and a warning briefly flashes.
The handbrake warning doesn’t sound.
I inadvertently left it on one click this morning. I had driven half a mile before I noticed.
It’s weird.

 

[Tazzieman]

More weird. yesterday the car started bonging each time I turned the indicator on, either side.
But it's OK today! Maybe there is a ghost in the machine?

 

[emax]

It would be helpful to know the respective SW versions.

The last four digits would for the time being suffice.
e.g. SW1946

 

[Tazzieman]

1946 here

 

[emax]

So this can affect the updated cars as well.
That's a bit worrying.
