How can I spot if I hav a rear e-diff on my RR AB MY2011.5 ?

I have
Power Train & Drive - Adaptive Dynamics [027CW];
Towing Equipment - Towing Prep ROW [028BR]

I need to know as I need to change all the oils of the car as it has reached 10+yo and 100k miles

thanks

The ptf shows both diffs. The obvious indication is seen by looking towards the diff from under the rear to see what the diff looks like where the left driveshaft connects - a neck for the open diff or no neck for the ediff.

Thanks
a part from lifting the car and look underneath, as I need to order the specific oil before bringing the car to the service garage, any other way to spot it?
Inside the car thru HMI, specific code to linked with the VIN number?

Thanks

you see a padlock on the rear diff If have one SOLD | Tuned MY 2011.5 Range Rover Autobiography 4.4 TDV8 Orkney Grey | e-diff | ACC

New Toy: Unimog U1550L/37
New : G350D

You only have to look forwards from under the left side of the bumper to spot the driveshaft and left side of the diff.

A green rear padlock isn't conclusive.

Thanks to everybody
I will follow you advise
