I just bought 2016 RR Sport Supercharged 5.0 V8 (GA597312) with 57k miles and 90 days of limited warranty from Autonation.It seems rear dif oil (every 5 yrs needed) was never replaced. Need help with two things:
1. What oil is LL recommended for this application? And how can I verify that by myself? Owner manual has only engine oil info. VIN web search is very unclear about fluids.
2. Is a seller (bmw dealer in my case) responsible for such missed compulsory maintenance? The given warranty doesn't cover cases if the vehicle was not maintained accordingly. So, any dif issues automatically withdraw and it worries me a lot. There are also missed transfer case oil, spark plugs and supercharger belt replacements.
Appreciate any advice on it.

 

The dealer is not responsible for the maintenance. Take it to a Land Rover dealer or independent shop and get it serviced.

 

1. What about the oil. How to look up the right fitment?
2. I want to have it serviced, but it's under 90 days warranty and it states that coverage may be denied if required maintenance procedures are not followed. Shortly, they gave a warranty, but it'll not cover because there are missed maintenance.
A seller should replace it and not because of expenses for those replacements, but because a seller should take responsibility for any damages which may happen because of items they needed to complete before selling.

 

I'm wondering on these issues as well. We are about to get a 2018 RRS Dynamic and I saw know records from the CarFax nor the dealer selling it to me that the transmission, Diffs, transfer case, power steering, coolant, belts etc have ever been replaced. And the extended warranty I am purchasing states the same about not maintaining required maintenance. Looks like I will be changing some fluids. If I do it and record it,. would it satisfy the requirements for the warranty?
