Land Rover Range Rover D350
The 3.0L Ingenium straight-six diesel with 48V mild-hybrid is more refined than the 2.0L diesel. Main issues: oil filter housing recall N908 (fire risk, 2021–2025), EGR coking and DPF on short trips. The 48V DC-DC converter is the designed-in weak link of the MHEV system.
D350 L460: fresh start with familiar strengths
In the new Range Rover L460 the D350 is even quieter and more refined than before. No visible compromises on ride comfort. The inline-six diesel matches the vehicle's premium aspirations — better than some petrol units.
Engine Weaknesses 6
Incorrect plastic specification for the Ingenium I6 oil filter housing. The housing can crack and spray engine oil under pressure onto hot components such as the turbocharger. Fire risk. Recall N908.
Symptoms: Visible oil leak, oil puddles after parking, oil warning light, in severe cases smoke or fire
The DT306 electronic turbocharger actuator develops faults from overheating and deposits. Repair is labour-intensive due to the engine layout.
Symptoms: Power loss, engine warning light, uneven acceleration, delayed turbo response
The DT306 common rail injectors can fail from fuel contamination and internal wear. On the inline-six diesel all 6 injectors are affected.
Symptoms: Rough idle, diesel knock, black smoke, misfires, engine warning light
The DT306 EGR system carbons up particularly with short-trip use. A clogged EGR cooler raises operating temperatures and promotes overheating.
Symptoms: Rough idle, power drop, black smoke under acceleration, engine warning light
The DT306 DPF blocks with predominantly urban driving. Forced regeneration cycles increase fuel consumption and can cause oil dilution.
Symptoms: DPF full warning, reduced engine power, strong fuel smell from exhaust
On the 48V mild hybrid system, the DC-DC converter from 48V to 12V fails. Since MHEV vehicles have no conventional alternator, the 12V battery drains — complete vehicle shutdown is possible.
Symptoms: Charging system fault warning, red battery symbol, dimming lights, infotainment shutdown
Vehicle Weaknesses 4
Even on the new generation, early L460s show compressor failures and height sensor faults. ABS modulator noises addressed via OTA update. Repairs are inherently expensive. Regular maintenance extends service life.
Pivi Pro freezes, restarts or loses connectivity. Proximity auto-lock sometimes fails. OTA updates arrive regularly but occasionally introduce new problems. Coolant level warnings and engine warning lights due to ECU errors are known.
Flush electric door handles make loud noises when locking and unlocking on all four doors. Proximity function fails, doors must be opened manually by pressing a button. Problem officially acknowledged by JLR Engineering.
Early production years show panel gap variation at tailgate and doors as well as wind noise from door seals that do not sit correctly. MY25 model with revised door mirrors shows significantly less wind noise.
