Introduction
When it comes to the Range Rover brand, one of the most frequently asked questions we get is, "but, is it true that the 3.0 TDV6 engine breaks down easily?" The answer is complex and depends on several factors. In particular, this type of PSA-derived engine can be considered delicate and suffers from a congenital defect accentuated by the regeneration of the DPF (Diesel Particulate Filter) or also called FAP.
In this article, we will explore the causes of failures and give you practical advice on how to prevent costly failures and prolong the life of your Range Rover engine.
What is the DPF?
DPF, short for Diesel Particulate Filter, is an essential component of modern diesel engines designed to reduce air pollution. Its main role is to capture and retain soot particles (or particulate matter) produced during the combustion of diesel fuel. These particles, if not filtered, would be released into the air, contributing to pollution.
Inside the filter, soot particles are accumulated until a certain threshold is reached. At that point, a regeneration process begins: the filter "self-cleans" by raising the temperature to burn and convert the accumulated particles into ash, which is much less harmful and can be easily expelled from the exhaust system.
The problem with the DPF regeneration
The process of the DPF regeneration can present problems. Particularly in Range Rover diesel engines with EURO 5 specifications. On short journeys and at low temperatures, the DPF may not reach the necessary temperature to effectively burn off soot. This can lead to filter clogging, impairing engine performance and potentially causing failure.
To prevent DPF clogging, more diesel fuel is injected. This operation serves to increase the temperature of the exhaust gases, thus facilitating the burning of particles accumulated in the filter.
For EURO 6 models, the ADBLUE system has been implemented, which involves the use of a special liquid for Diesel engines, injected into the filter to optimize the combustion of residues. However, even in EURO 6 vehicles, the increase in injected diesel fuel can occasionally cause it to mix with engine oil. This phenomenon, due to the difference in viscosity between the two fluids, can adversely affect the lubricating properties of the oil, compromising the effectiveness of the protective film between the moving parts of the engine, such as the bushing and the crankshaft.
So what happens?
Crankshaft failure
One of the consequences of mixing diesel and engine oil in engines is the risk of crankshaft overheating or malfunctioning of the bushings, which may spin abnormally and, in extreme cases, melt or deform inside the engine.
On TDV6 and SDV6 engines, this situation can lead, in some cases, to unannounced crankshaft rupture, particularly between the third and fourth cylinders, where cracking can occur.
Should it occur, engine replacement can be costly, with costs ranging from 15,000 to 18,000 euros.
Prevention and Solutions
Fortunately, there are preventive measures owners can take to reduce the risk of such failures:
- One recommended practice is to change the engine oil more frequently than Land Rover's standard directions. Ideally, the oil should be changed every 10,000 to 15,000 kilometers, along with the oil filter. Although this maintenance may seem expensive initially, it is an investment that can save considerable future expenses.
-
Another effective strategy is the removal of the DPF. This procedure eliminates the main cause of failures related to the mixing of diesel fuel with engine oil. Without the dpf, not only the problem of oil viscosity difference is avoided, but also the consumption of diesel and ADBLUE is reduced. In addition, eliminating EGR (Exhaust Gas Recirculation) improves engine cleanliness, reducing particulate matter formation and the risk of filter clogging.

Conclusion
In conclusion, while Range Rover vehicle engines are prone to potentially costly failures, taking appropriate preventive measures can significantly prolong engine life and improve vehicle reliability. Changing the oil regularly and considering FAP removal are key steps to keeping your Range Rover in top condition. Remember that preventive maintenance is always more cost-effective than repairs after a breakdown.

FREQUENTLY ASKED QUESTIONS
- Is it necessary to remove the DPF on all Range Rover models?
Removal of the DPF is especially recommended for models with EURO 5 and EURO 6 engines, but it is always a good idea to consult a specialized mechanic. - How often should the oil in a Range Rover engine be changed?
Ideally, the oil should be changed every 10,000 to 15,000 kilometers, depending on the use of the vehicle. - What are the symptoms of an impending problem with the crankshaft?
Symptoms may include unusual noises coming from the engine, loss of power, and abnormal vibration. - Can regular maintenance guarantee that the crankshaft will not fail?
Although regular maintenance cannot guarantee 100% failure prevention, it significantly reduces the risk of serious problems. - Are there alternatives to DPF removal?
In addition to DPF removal, regular use of fuel additives and adopting a driving style that favors longer routes can help reduce the risk of DPF-related problems.
