Three Land Rover model lines have used the 2.0 Ingenium engine: the Discovery Sport (diesel from the 2016 model year, petrol from the 2018 model year), the fifth-generation Discovery from 2017 and the Defender from 2020. In Land Rover models the 2.0 Ingenium has run from 150PS in the entry diesels to 300PS in the most powerful petrol. A familiar badge is not proof on its own, because some early cars used older engines under the same names, so the model year matters as much as the model. This guide goes through each model, how to check your own car, and what owners should know about faults and servicing.
What the Ingenium Engine Is
Ingenium is Jaguar Land Rover's own modular engine family, built at the Engine Manufacturing Centre in Wolverhampton. Every version is aluminium and uses cylinders of about 500cc each, which gives a 1.5 litre three-cylinder, a 2.0 litre four-cylinder and a 3.0 litre straight-six from the same basic design. Production began in 2015, first in the Jaguar XE and then the XF, before the engine spread across the Land Rover range.
The Ingenium replaced engines that JLR had bought in: the 2.2 litre diesel developed by Ford and PSA, which uses a cam belt, and the Ford-based 2.0 GTDi petrol. Ingenium engines drive their camshafts with a chain rather than a belt. They were designed around Euro 6, which applied to new type approvals from September 2014 and to all new car registrations from September 2015, with a NOx limit of 80mg/km for diesels.
Land Rover Models with the 2.0 Ingenium Engine
Discovery Sport: Ingenium Diesel from 2016, Petrol from 2018
The Discovery Sport went on sale in 2015 with the previous generation of engines: the 2.2 litre diesel and the Ford-based 2.0 GTDi petrol. JLR's 2.0 Ingenium diesel replaced the 2.2 for the 2016 model year, badged TD4 and offered at 150PS and 180PS. Land Rover's 240PS twin-turbo version of the diesel, which uses two turbochargers working in sequence, also joined the Discovery Sport range, badged Sd4.
The Ingenium petrol followed for the 2018 model year in two outputs, the 240PS and 290PS Si4, and replaced the GTDi. When it arrived, the 290PS Si4 was the most powerful engine the Discovery Sport had been offered with.
The 2019 update brought 48 volt mild hybrid (MHEV) technology to the 2.0 engines, and later mild hybrid diesels were badged D165 and D200. From 2020 the range added the P300e plug-in hybrid, which does not use the 2.0 at all: it pairs a 1.5 litre three-cylinder Ingenium petrol of 200PS with a 109PS electric motor on the rear axle, giving 309PS combined.
The Discovery Sport is the only Land Rover in this list with a transverse engine, mounted across the car rather than front to back. That has consequences for the diesel's particulate filter, covered further down.
Discovery: Fifth Generation from 2017
The fifth-generation Discovery arrived in 2017 with three 2.0 Ingenium choices: the Td4 diesel at 180PS, the twin-turbo Sd4 diesel at 240PS and the Si4 petrol at 300PS. The Td6, a 3.0 V6 diesel offered alongside them, was not an Ingenium engine, so a Discovery Td6 is a different case altogether. In the Discovery the engine is mounted longitudinally.
For faults that affect the rest of the car, see our guide to Land Rover Discovery issues.
Defender: from 2020
The current Defender launched in 2020 with three 2.0 Ingenium four-cylinder engines: the D200 and D240 diesels and the P300 petrol. Alongside them sat the P400, a 3.0 six-cylinder petrol, and the range also included a P400e plug-in hybrid built around the 2.0 Ingenium petrol. Later model years moved the Defender's diesels to the 3.0 six-cylinder Ingenium, so the model year decides which diesel engine a Defender has. Like the Discovery, the Defender's engine is mounted longitudinally.
Land Rover Ingenium Engines at a Glance
- Discovery Sport: 2.0 Ingenium diesel from the 2016 model year at 150PS and 180PS, plus the 240PS twin-turbo Sd4; 2.0 Ingenium petrol from the 2018 model year at 240PS and 290PS; mild hybrid from the 2019 update; 1.5 three-cylinder P300e plug-in hybrid from 2020.
- Discovery (from 2017): Td4 180PS and Sd4 240PS diesels, Si4 300PS petrol. The Td6 V6 diesel was not an Ingenium.
- Defender (from 2020): D200 and D240 diesels and the P300 petrol at launch, plus the P400e plug-in hybrid. Later diesels use the 3.0 six-cylinder Ingenium.
How the 2.0 Ingenium Differs Between Models
Diesel and Petrol Are Different Engines
The diesel and petrol share the Ingenium design and dimensions, but they are separate engines. JLR codes the 2.0 diesel AJ200D and the 2.0 petrol AJ200P. The diesel uses high-pressure common rail injection directly into the cylinder, and its 240PS version has two turbochargers in series. The petrol uses direct injection and spark plugs. Most of the faults owners hear about belong to the diesel, because of the way it keeps its particulate filter clean.
Transverse and Longitudinal Mounting
In the Discovery Sport the engine sits across the car. In the Discovery and Defender it sits lengthways. It is sometimes said that a transverse engine is simpler to maintain, but that does not hold for timing chain work on the Ingenium: whichever way the engine is mounted, the chain drive is at the rear of the engine, at the gearbox end. It cannot be seen or adjusted at a service, and replacing it means removing the gearbox or taking the engine out.
Mounting also decides where the diesel particulate filter (DPF) sits. On the Discovery Sport the filter sits further back, under the floor, so it takes longer to reach the temperature it needs to clean itself on a short journey.
Mild Hybrid and Plug-in Hybrid Versions
The 2.0 mild hybrid uses a 48 volt belt-integrated starter generator. It recovers energy when the car slows down, allows the engine to stop as the car comes to a halt, and adds a little torque when pulling away. It is not a supercharger. JLR's 48 volt electric supercharger appears only on the 3.0 straight-six petrol, which also has a turbocharger, and no Ingenium engine has a belt-driven supercharger.
Land Rover's Ingenium plug-in hybrids are the Discovery Sport P300e, with the 1.5 three-cylinder, and the Defender P400e, with the 2.0 petrol. Both pair the engine with an electric motor and a battery that is charged from the mains, so they can cover short distances on electric power alone.
How to Tell Which Engine Your Land Rover Has
Start with the paperwork. The V5C logbook gives the engine size and fuel type, and the DVLA vehicle enquiry service on GOV.UK shows the same details from the registration number. Then compare the model year with the dates above.
Badges alone can mislead. A Discovery Sport badged Td4 or Sd4 from before the 2016 model year has the older 2.2 litre diesel, not an Ingenium, even though later Ingenium cars used the same badge names. The tailgate badge on newer cars, such as D200 or P300, shows the output rather than the engine family.
The engine block carries its own engine number, separate from the VIN, and a JLR specialist can read the build data from the car to confirm exactly which engine is fitted. Our guide on how to identify an Ingenium engine takes you through each check.
Known Issues on Land Rover Ingenium Engines
Timing Chain Stretch on the 2.0 Diesel
Timing chain stretch is the most reported fault on the 2.0 Ingenium diesel. It mainly affects engines built before revised chain, guide and tensioner parts arrived around 2019, although JLR has not published an exact build cut-off. The first sign is usually a metallic rattle from the back of the engine for a few seconds after a cold start. Left alone, a stretched chain can upset the engine's timing and, if it jumps or breaks, cause serious engine damage.
There is no UK recall for Ingenium timing chains, and there is no scheduled replacement. A garage diagnoses stretch from live camshaft and crankshaft correlation data and fault codes, and the repair is a revised chain, guides and tensioner kit fitted with the gearbox removed.
Oil Dilution and the Particulate Filter
This applies to the diesel engines. To clean its DPF, the engine regenerates the filter by injecting extra fuel late in the cycle to raise the exhaust temperature. If short journeys keep interrupting regeneration, some of that fuel washes past the piston rings into the sump and thins the oil, which then protects the timing chain, bearings and turbocharger less well. The Discovery Sport's underfloor filter layout makes it more prone to this than the longitudinal models.
Signs include a rising oil level on the dipstick or level display, a fuel smell from the oil, or a service message appearing earlier than expected. If the amber DPF light comes on, Land Rover's advice is to drive above about 37mph for around 20 minutes so the filter can regenerate. A red light means performance is reduced and the car needs checking.
Turbocharger and Fuel System Recalls
Turbochargers depend on a steady supply of clean oil, so diluted oil and oil feed faults show up there too. The Discovery Sport has two DVSA recalls in this area, neither of them for the timing chain: R/2018/036 for fuel rail end caps that could leak, on cars built from May 2016 to January 2018, and R/2025/178 for a turbocharger oil feed pipe clamp fitted the wrong way, on cars built from January 2024 to May 2024. You can check any car by registration on the GOV.UK vehicle recall checker.

Servicing a Land Rover Ingenium Engine
JLR uses a flexible, indicator-driven service schedule, so the right interval depends on your car and how it is used. Follow the service indicator and the handbook rather than a fixed mileage. On a diesel, do not reset a service message that appears earlier than expected. The engine has no sensor for fuel in the oil, but the engine computer estimates dilution and brings the service forward when it judges the oil needs changing.
The oil specification matters as much as the viscosity. The 2.0 Ingenium diesel needs oil to JLR specification STJLR.03.5007 (0W-30), a low-SAPS oil that protects the DPF. The 2.0 petrol needs STJLR.03.5006 (0W-20), which replaced STJLR.51.5122 from April 2018. Check the specification printed on the bottle, not just the grade, and treat the handbook as the final word.
Specialists commonly advise an extra oil and filter change between services for diesels that spend most of their time on short journeys. Diesel Land Rovers also use AdBlue: top it up from non-drip bottles rather than commercial HGV pumps, whose flow is too high, wipe up any spills because it is corrosive, and do not let the tank run dry, as the car will not restart once it is empty.
Software updates matter too. JLR releases engine software updates, and a specialist with equipment that reads JLR systems can check whether your car has the latest. Our Ingenium engine maintenance guide covers oil, dilution and protecting the timing chain in full.

Frequently Asked Questions
Which Land Rover models have the 2.0 Ingenium engine?
The Discovery Sport (Ingenium diesel from the 2016 model year, Ingenium petrol from the 2018 model year), the fifth-generation Discovery from 2017 (Td4, Sd4 and Si4) and the Defender from 2020, whose D200 and D240 diesels and P300 petrol were 2.0 Ingenium engines at launch. The Defender P400e plug-in hybrid also uses the 2.0 petrol.
Is every Discovery Sport Td4 an Ingenium engine?
No. A Discovery Sport badged Td4 or Sd4 from before the 2016 model year has the older 2.2 litre diesel, which uses a cam belt. Cars from the 2016 model year onwards have the 2.0 Ingenium diesel. Check the model year on the V5C, or ask a specialist to read the build data from the car.
What engine does the Discovery Sport P300e use?
The P300e plug-in hybrid uses a 1.5 litre three-cylinder Ingenium petrol of 200PS, paired with a 109PS electric motor on the rear axle, for 309PS combined. It is not a 2.0 engine.
Does the Land Rover 2.0 Ingenium mild hybrid have a supercharger?
No. The 2.0 mild hybrid uses a 48 volt belt-integrated starter generator, which recovers energy and gives a small torque boost when pulling away. JLR's electric supercharger is only fitted to the 3.0 straight-six petrol, and no Ingenium engine has a belt-driven supercharger.
Is there a UK recall for Land Rover Ingenium timing chains?
No. There has been no UK recall for Ingenium timing chains, and any goodwill outside warranty is at JLR's discretion. The Discovery Sport does have UK recalls for other parts, including fuel rail end caps (R/2018/036) and a turbocharger oil feed pipe clamp (R/2025/178). Check your car by registration on the GOV.UK vehicle recall checker.
