Frequently asked questions

What is the LR078840VA fuel pressure regulator and what does it do?
The LR078840VA is a fuel pressure regulator (pressure control valve) for the 3.0 V6 diesel high-pressure injection system. Mounted on the high-pressure fuel pump, it meters fuel into the common rail so the engine control module can hold the commanded rail pressure across the full operating range.
What are the symptoms of a faulty fuel pressure regulator?
A faulty fuel pressure regulator on the 3.0 V6 diesel typically causes hard starting, rough running, power loss or rail-pressure fault codes. If the regulator can't hold the commanded pressure the engine may go into limp mode. Confirm with a pressure reading before replacing.
Which models and engine does this regulator fit?
The LR078840VA fits the 3.0 V6 diesel engine in the Discovery 4, Discovery 5, Range Rover L405, Range Rover Sport L320 (2005-2013) and Range Rover Sport L494. It's the pressure control valve for the diesel high-pressure injection pump. Confirm your engine and VIN before ordering.
