Don't Have Reg..?
Range Rover
Our Ingenium expertise extends across the wider Range Rover and Range Rover Sport range, which shares the same 2.0 and 3.0-litre engine family fitted to the Discovery 5.
Land Rover
We diagnose and repair every Discovery 5 engine, from the 2.0-litre Ingenium SD4 diesel to the 3.0-litre SD6 and D300 units, addressing oil dilution, timing chain and injector issues.
Jaguar
The Discovery 5's Ingenium engines are shared with several Jaguar models, so the diagnostic knowledge we've built on this platform applies equally well across both marques.

Ingenium Care
Proactive Diagnostics
Ahead of the Curve on Ingenium Engine Care
The Discovery 5 was Land Rover's first Discovery built entirely around the Ingenium engine family, and as these vehicles reach higher mileages, the specific issues this generation is prone to are becoming increasingly relevant to owners.
Our technicians train specifically on Ingenium petrol and diesel engines, understanding the particular failure points around oil dilution, timing chain tensioner wear and injector performance that differ from older Land Rover engines. We use manufacturer-level diagnostic equipment to confirm any fault before recommending work.
Getting ahead of these issues with proactive servicing and honest advice is central to how we approach every Discovery 5 that comes through our workshop.
Understanding Oil Dilution Before It Becomes a Problem
Diesel Ingenium engines can experience oil dilution, where unburned fuel enters the engine oil during regeneration cycles, gradually reducing lubrication effectiveness. It's more common on vehicles used mainly for short journeys that rarely reach full operating temperature.
Left unmonitored, oil dilution can accelerate engine wear over time, which is why we check oil condition and dilution levels as part of any Discovery 5 diagnostic, along with reviewing servicing history for patterns that suggest a higher risk.
Simple changes, like occasional longer journeys or more frequent oil changes, can significantly reduce the risk, and we're happy to advise on what makes sense for how you actually use your vehicle.
Oil Dilution Analysis
Preventative Maintenance
Repairs That Keep Pace With a Modern Engine
A Discovery 5 engine repair needs to reflect the sophistication of the Ingenium platform, not treat it like an older, simpler diesel or petrol unit. That precision runs through everything we do.
Whether it's timing chain tensioner replacement, injector diagnostics, or a full engine rebuild, we use manufacturer specifications and genuine or OEM-quality components throughout, verified with proper post-repair testing. Reconditioned and used engines are checked thoroughly before fitting.
The outcome is a Discovery 5 that performs reliably, with a warranty behind the work and a specialist team who understand this engine generation properly.

As the earliest Discovery 5s approach a decade on the road, the Ingenium-specific issues that affect the wider Jaguar Land Rover range are becoming more relevant to this generation, and getting ahead of them matters.
Because we work specifically with Land Rover and Jaguar engines, we understand exactly what to check for on an Ingenium unit, from oil dilution sensors to timing chain tensioner wear, rather than applying generic diesel or petrol assumptions. That focus means problems are identified before they escalate into costly repairs.
Every quote is provided in writing before work begins, so Discovery 5 owners always know exactly what they're paying for.
