One owner also reported serious rot on a TD5's driver's side chassis rail. Replacing that metal's a big job that means taking off the fuel tank among other parts, and towing weakens the area further, so a car that's pulled trailers needs a closer look underneath.
Recall paperwork matters just as much. In 2004 Land Rover recalled the Discovery 2 for a possible loss of ABS braking, a throttle that could stick open, an underbonnet fire risk on the TD5 and V8, and a TD5 rear fuel line that could chafe on the wiring harness. A seller who can't show the ones that apply to the car were done is handing that risk straight to you.
By 2007 so many TD5 cylinder heads had cracked that replacements ran short, so a TD5 with oil in the coolant or a coolant level that keeps dropping isn't one to take home. Cars built in 2002 also had a TD5 fuel tank problem that left them parked up for months in late 2004 while owners waited on parts, so ask what's been done to the tank on a 2002 car.
On a TD5 diesel, buy one that's had its oil pump sprocket bolt swapped for the threadlocked bolt Land Rover sells. That bolt holds the sprocket on the oil pump shaft down in the sump, and owners have reported them coming loose and wrecking the engine. There's no Land Rover recall for it, so don't assume it's been fitted unless there's a receipt.
Over 100k miles, one owner's advice is to fit a bright extra oil pressure warning light, so a loose bolt shows itself before it chews out through the sump. The same owner says to swap the cylinder head wiring harness the moment there's a misfire, before oil creeps along the cable into the ECU. One owner's Discovery 2, at 125,000 miles, needed three ECUs in four years, the first after oil got into it.
Cracked heads are the TD5's other big risk, and by 2007 enough had failed that replacement heads ran out. The V8 shares the 2004 underbonnet fire recall with the TD5, so get proof that work was done whichever engine you pick. Stick to original-equipment clutch and brake parts, too; one owner found pattern versions badly made and quick to fail.
Get underneath and look hard at the rear of the chassis and the driver's side rail, since both have rotted on owners' cars, and check the rear brake pipes for corrosion too. Look at the brackets holding the ACE actuator to the chassis; they're prone to breaking, and a few owners were told to replace the entire chassis over it.
On the test drive, listen for a misfire on a TD5; if there's one, the cylinder head wiring harness needs replacing before oil creeps along it into the ECU. Ask the seller for a full diagnostic readout, because alternator failures have been traced to the ECUs feeding a ripple of alternating current into the 12 volt supply. Check the coolant for oil, and look at the level before and after the drive for any loss.
Water's the other enemy. The vent plenum drains carry conical bungs that clog with debris, and once they do, water reaches the fusebox and kills the electrics, so check they're clear and look for damp around the fusebox. Wiring from the front of the car to the rear air suspension controls can corrode and fail when wet, so make sure the rear suspension raises and lowers properly.
Open and shut the rear door several times, because a spring in its lock can break and let the door swing open on the move. Try the rear wiper too, as its motor's known to fail. Then ask for receipts for the oil pump bolt and any head, harness or ECU work, plus proof that whichever of the 2004 recalls cover the car were carried out.
