Prospective owners of the Range Rover Evoque and Discovery Sport with Ingenium engines need to be aware of certain reliability concerns to make an informed decision.

Oil Dilution Concerns in Diesel Variants

One of the most prominent issues reported by owners of Ingenium diesel engines is oil dilution. This occurs when fuel mixes with the engine oil, diminishing its lubricating properties and increasing wear on engine components. Oil dilution is exacerbated by frequent short trips that prevent the engine from reaching its optimal operating temperature, resulting in incomplete fuel combustion. Symptoms of oil dilution include increased oil levels, thinner oil consistency, and a faster-than-normal degradation of oil quality.

To mitigate oil dilution, it is recommended to:

1. Reduce idling time.
2. Opt for longer trips to allow the engine to reach and maintain operating temperature.
3. Regularly check oil levels and quality.
4. Perform oil changes more frequently than the standard service intervals.

Timing Chain Issues

Timing chain failures have been a notable issue in Ingenium engines, particularly affecting models up to 2019. The timing chain can stretch over time, causing a rattling noise during cold starts and potentially leading to severe engine damage if the chain jumps a tooth or snaps altogether. This problem has been linked to the use of poor-quality steel in the chains and inadequate tensioners.

For owners experiencing timing chain issues, it is essential to:

1. Listen for unusual noises during engine start-up.
2. Schedule regular inspections for the timing chain.
3. Consider preemptive replacement of the chain and tensioners if symptoms or mileage warrant it.

EGR and DPF Problems

Exhaust Gas Recirculation (EGR) systems and Diesel Particulate Filters (DPF) in Ingenium diesel engines can also present challenges. The EGR valve, responsible for reducing nitrogen oxide emissions, can become clogged with carbon deposits, leading to rough idling, poor acceleration, or even stalling. Similarly, the DPF, designed to capture soot from the exhaust, can get blocked, resulting in reduced engine power, decreased fuel economy, and increased exhaust smoke.

Steps to manage EGR and DPF issues include:

1. Cleaning or replacing the EGR valve as needed.
2. Ensuring the DPF is regularly regenerated through longer, high-speed trips.
3. Utilising high-quality fuel and engine oil to minimise carbon buildup.

Recommendations for Potential Buyers

Given these issues, potential buyers should consider the following recommendations:

1. Regular Maintenance: Adhering to more frequent oil change intervals, especially for diesel variants experiencing oil dilution.
2. Professional Inspections: Routine checks of the timing chain, EGR valve, and DPF to catch problems early.
3. Driving Habits: Incorporating longer trips and reducing idling time to maintain engine health.
4. Warranty Coverage: Ensuring that any used vehicle purchase includes a warranty that covers engine components, or opting for vehicle models produced post-2019, which may have revised parts and fewer issues.

While Ingenium engines offer notable performance and efficiency improvements, being aware of these potential issues and proactively addressing them can greatly enhance the ownership experience.
