fairly common on the L494, but they should replace it - there's a kit from LR that they need to order --

Mine had just such a leak - they replaced the whole diff. MY2016 HSE D SDV6 - gone due to fuel dilution problems.

+1 had my rear diff seal done a few weeks ago under warranty. No replacement / sounds like they applied the LR repair kit.

An update on this: the rear diff started whining after the car was standing for 3 weeks.

The head mechanic also heard it as soon as we went for a test drive, and he reckons the slight oil loss might have caused some damage to the bearings.

This repair/replacement will be covered by the service plan. Whistle --

Just heard back from the dealership - it is indeed the rear diff, and they have to motivate to HQ to get a replacement one --

fokit man, that sucks!

Mine was done in Oct 2019, then the rear diff started whining in Nov and had to be replaced.

I hope it doesn't happen again because now my car is out of service plan! --

darn it, just came back from a 400km drive, and I am hearing that dreaded high-pitch whine again. Banging Head

but this time it doesn't seem to be coming from the back but more from the front right of the car.

And I have a long road trip in 2 weeks' time Censored Censored Censored --

How did that end up? Did LR cover the cost?

Ours was replaced 8000 miles ago and has just gone again and our LR dealer are quoting £1,000 to open it up and see what might have caused it, only refunded if they determine that it isn't something new. Not impressed.
