I had this problem on my wife's 2001 Freelander and it ended up being a loose battery terminal.  There was plenty of electricity to run lights, radio and so forth.  When the starter solenoid kicked in you could hear it click, but the loose terminal couldn't carry enough power to turn the starter motor.  Battery was fine in all respects and when I tightened the terminal, everything worked like it's supposed to.

I don't wish to worry you but I think the turbo kicks in at around 2500rpm and it sounds like it isn't doing so, hence the management light coming on. It could be that failing. Be careful here, apparently the turbo uses the engine oil to maintain its operating temperature and if the turbo seals fail in anyway it eats the engine oil, with the resulting total failure of the power unit. So if you do nothing else, keep an eye on the engine oil level. (You may also notice oil smoke out the exhaust as well).
Unfortunately it looks like a trip to the dealer for them to check what the engine management is saying.

yeah, don't drive so fast!!!!...seriously i would do what has to be done anyway to start. change fuel filter, air filter, spark plugs, spark plug wires. these have to be done at some point if they haven't been.. if that solves your problem, if not look at fuel pump, injectors.u didn't say if it used to go faster, maybe there is a limiter.

From 53 reg onwards, diesel pump is under R.H. rear wheel arch, hidden by the plastic wheel arch liner. Older versions have combined fuel pump/sender in the tank (under R.H part of rear seat).
You should be able to hear a faint purr from the pump when ignition is turned on but engine not yet running.
