Q: A Land Rover Discovery 4 (L319), equipped with a TDV6 2.7L diesel engine, has a mileage of 150,000km. Now it has a weak acceleration problem. The engine speed cannot reach 3000r/min even if the accelerator pedal is pressed to the bottom. The electronic control system prompts that the oil pressure in the common rail system is too low. Check that the exhaust pipe is not blocked. What is going on?
A: This is a typical case of vehicle failure caused by wear of the high-pressure oil pump. Replacing the high-pressure oil pump can eliminate the vehicle failure.
