They can drive really well, but the earlier Ingenium diesels need buying carefully — service history and usage pattern matter more than most other checks combined.

Technician Overview
The 2.0 Ingenium diesel is used across a huge number of Discovery Sports and Evoques. They can drive really well, but the earlier engines in particular need buying carefully.
For 2015–2019 models, service history and the way the vehicle has been used are two of the biggest things we look at.
Timing Chain Stretch
Timing chain stretch is one of the main concerns on earlier Ingenium diesels. Warning signs can include:
- Rattling on start-up
- Excessive timing-chain noise
- Engine management faults
- Poor running in more serious cases
Poor servicing, degraded oil and extended oil-change intervals can all make matters worse.
Oil dilution is another concern, particularly where repeated DPF regenerations have taken place. Diesel can contaminate the engine oil, reducing its ability to protect the timing chain, turbo and other internal components. This is why we'd much rather see regular oil changes with the correct specification oil than a car that's simply followed the longest possible service interval.
Turbocharger Failure
Turbo failure is another issue seen on these engines. Again, oil quality and servicing play a big part.
Before buying, we'd check for:
- Excessive turbo noise
- Whistling or siren-type noises
- Lack of boost
- Smoke under acceleration
- Oil leaks around turbo pipework
- Previous turbo replacement history
A replacement turbo isn't something you want to discover the vehicle needs just after purchase.
DPF Problems
The DPF can also cause trouble, particularly on vehicles used predominantly for short, stop-start journeys. We've also seen DPFs fail internally through cracking, rather than simply being blocked with soot.
Repeated short journeys can prevent successful regeneration and contribute to:
- DPF warning lights
- Frequent regeneration
- High soot loading
- Oil dilution
- Reduced power
- Engine management faults
Technician Verdict
Early Ingenium diesels aren't necessarily cars we'd automatically avoid, but we'd be extremely selective. A well-maintained example with regular oil changes and evidence of longer-distance driving is a very different proposition to one that's spent its life doing short journeys on extended service intervals.
