Had a 48k service, but at 33k (includes diff oils I believe @ dealers), then engine oil and filter at 45k. As a second hand buy from a dealers, it is out of the manufacturers warranty, and is covered by a third party's warranty. I think they'll try and play the "it hasnt had a dealer service card" to dishonor the claim, even though in enginerring terms offending item has clearly had the servicing required at the main dealers.
The diff whinned, on overun, ever since we acquired the car at 36k (May 08). Didnt think it would be a problem, but did check the oil level at 45k service which was fine. Only used for onroad, with occasional heavyish towing (3 tonnes). When it went it was after a steep hill with a cattle box on and livestock. After running Landrovers within agriculture for 25 years, this is the first occasion for major mechanical failure, I can only assume the defenders (110 with a salisbury Axle) are proper Landrovers now and will have to return to my old steady TDI 110!
