Actually I don't like the more modern EU compliant engines, too much to go wrong.
Not against electronics as they can be reliable, but with the latest EU mode bringing in engine disabling for running out of pee, for EGR failure, various things which do not matter 1000s of miles from a dealer.
The Defender was best pre Transit engine, when it still had one of the the two Land Rover designed engine families in it. That being either the 2.5 direct injection based on series engine (300TDi) or the 5 pot lump to replace it (TD5).
With a Land Rover you want it to be repairable, you don't want to be stuck in Africa because the EGR failed. Even my 2003 100" estate can run fine with no EGR and only one working sensor if it had to.
