OK, so I'm going to update this again, because it's absurd. Today I had to go to the office - 80 miles each way of almost entirely motorway. This is (realistically) the best possible use case for an engine. So I checked the service countdown before I left - 14,250 miles. Two lots of 80 miles later, it says 13,450 ! So 160 miles of low intensity motorway driving consumes (interestingly) exactly 5x that from the service indicator. Whereas the DEF has refill has dropped by *less* than the actual mileage.
This is my first Range Rover and three weeks into ownership, honestly, the amount of stupid in it is doing my head in. I was lured into buying because of the style and the Britishness. It does have reasonably nice leather. And a split tailgate. And
Range Rover is an icon. But living with it, it's clear the nav / infotainment was put together by six people that didn't talk to each other, the seats were designed by Quasimodo, and the "amazing ride quality" is just very very soft primary ride with fancy ARBs to stop it falling over when you go around a corner, coupled to stiff secondary to pretend it has some feedback. Which it doesn't, sadly.
So unless I have a sudden epiphany in the next couple of weeks it's getting chopped in and I'm going back to "zee Germans" because I've never had this kind of nonsense from those guys.
Anyone want to buy an extremely disappointing 2017 SDV8 Autobiography ??
