New D4 vibration

Hi Nicky,
You really need to take it back to the dealership to have this sorted. As per your other thread it could be due to a number of reasons including incorrect pre-delivery checks.
Can I ask why you have started a new thread on this? Just curious!
Cheers, Mungus

The dealer has so far isolated this problem to the e-diff .
Not sure how this would account for the symptoms?

Any update?

Called the service manager, apparently the e-diff was failing, metal filings
in it! Waiting on new diff from UK. Dealer loaned me another D4, nice PR.

Installed new e-diff with LRA's approval. This was not the cause of the vibration 60kph to 80kph, so they are now clueless. Any diagnosis or actions? Would selecting neutral at say 70kph help the diagnosis?
Needless to say, I'm extremely disappointed.

Transmission(torque convertor) transfer case, out of balance tail shafts, CVs, harmonic balancer, engine mounts, front diff, where does it feel like it's coming from, can you feel it through the steering wheel or floor??

Thanks, as well as the steering wheel, I can feel it thru my bum when in the passenger seat

Turns out, it was the rear prop shaft. Makes you really paranoid, an undiagnosed unrelated e-diff problem uncovered during the hunt.
How many un-diagnosed build problems are there, to come out later to bite you, even after the warranty period?
Back to the old LandRover reputation.

Back to the old LandRover reputation.

At least they found it, some dealers are not renowned for there ability to find things or take any helpful advice.

I remember having a nagging suspension fault, where we kept going back to the dealer with it, they ended up bring LRA into it and even there (expert

) tech couldn't find it, I had mentioned a couple of times that we kept getting the fault code for the left side height sensor, still no idea.

Anyway, we got a nastey call from them saying that they had found the issue and it was apparently all the weight of the bullbar had destroyed the front airbag assembly and as a good will gesture, replaced them

I asked if they had replaced the height sensor, he said no, there's nothing wrong with it, it was all the accessories causing the issue

So my missus had already ordered a sensor from our indy mechanic, so on the way home we dropped in and picked it up.

Next trip, yep, suspension fault again, wipped out the new sensor, replaced it, no more suspension faults

Funnily enough, they wouldn't show us the old airbag assembly
