DieselPumpUK is repairing a Land Rover Discovery after two engine replacements, the most recent of which failed after just 900 miles. Land Rover’s 2.0-litre diesel Ingenium engine is, on its own, a mitigated disaster, plagued by well-known reliability issues: timing chain failures due to plastic guide wear, oil mixing with fuel, and turbocharger failures.

Clearly, Land Rover rushed development of the Ingenium engine, turning what should have been a sophisticated British design into a complicated mess.

Compare it to a typical Japanese hybrid engine—more mechanically complex yet executed as a symphony of simplicity. In Japan, complexity has been simplified; at Land Rover, the complex was overcomplicated.

Land Rover’s Ingenium engines are under-engineered, built on a low development budget, and assembled with cheap parts. The equation is simple—cheap parts lead to premature failure.

I know a number Discovery owners who have experienced the same fate: terminal engine failure, expensive repair bills. DieselPumpUK undertakes the exhaustive process to remove the failed 2.0-litre Ingenium and replace it with a new one.

It almost seems counterproductive. If two Ingenium engines have already failed, the odds are high that the replacement will eventually suffer the same fate.
