Land Rover Range Rover Sport D250
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.
D250 new: efficiency meets comfort
The D250 in the new Sport is noticeably more mature than in its predecessor. Quieter, smoother, more economical — and still enough pull for everyday use. High-mileage drivers will appreciate the combination of inline-six smoothness and moderate consumption.
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
Software faults trigger engine management and gearbox fault messages without any mechanical defect. Particularly affects MHEV variants. OTA updates address known cases; ECU reprogramming at the dealer often necessary.
Despite the new generation, early L461s show compressor failures and faulty height sensors. ABS modulator noises addressed via OTA update. Air suspension remains inherently expensive to repair when it fails.
Pivi Pro system freezes while driving or restarts spontaneously. Android Auto and Apple CarPlay drop out wirelessly. Navigation and voice control issues known. OTA updates bring improvements but do not resolve problems completely.
Early production years show uneven panel gaps at the tailgate, doors and bumpers. Door rubbers do not sit correctly and generate wind noise at motorway speed. MY25 models with revised door mirrors are noticeably better.
