2.0 Ingenium DPF Failure

The 2.0 Ingenium diesel engine was designed with emissions and efficiency in mind, one key component in achieving this is the Diesel Particulate Filter (DPF).

This unit traps soot particles from the exhaust and burns them off during a process known as regeneration. Manufacturers claim near complete removal of all diesel soot during this process, and while most modern diesels have this system, it has one major drawback, to complete the regeneration process the car has to be driven for 25 to 40 minutes at a speed of over 40 mph.

This guide explains the symptoms, causes, and long-term consequences of DPF failure on Ingenium-powered vehicles, particularly how short journeys, poor oil quality, and neglected servicing can lead to clogged filters, oil dilution, and even failed timing chains and engine damage.

For more information on the DPF system, please see our DPF Maintenance page.

To get the DPF to temperature more quickly if the system detects a regeneration is required, extra fuel is injected into the combustion chamber. However if you are only doing short journeys then the regen process will be incomplete and all the extra fuel ends up in the engine oil, diluting it as a consequence.

This is extremely harmful to engine components, and results in premature wear on all components. However, it will also result in the DPF continuing to fill with soot and block up.

The main sign that you’ve a real issue with your DPF is the warning light on your dashboard, it will say ‘Exhaust Filter Nearly Full’ in Amber or even worse in Red it will say ‘Exhaust Filter Full Visit Dealer’, and if you continue to drive with these warning lights on then you will likely block the DPF beyond the point it can be cleaned and it will have to be replaced.

PLEASE NOTE: You must never ignore the ‘Service Required’ message on your dash, even though you may only have done a few thousand miles since your last service you could have thinned your oil to the point wear it triggers the warning.

How is the Problem Solved

If caught quickly enough, it may be possible to perform a forced regeneration to unblock the DPF or if this fails, a manual clean with the DPF removed. However, if you have tried to clean your DPF and the warning lights come back on, this unfortunately it means the particulate filter will need to be replaced.

Removal of the Diesel Particulate Filter on the 2.0D Ingenium unit is achieved in 6 steps:

1. Remove the Nox and pressure sensors
2. Remove AdBlue injector
3. Loosen EGR pipe 10mm nut
4. Remove 3x 13mm nuts from CAT
5. Separate DPF from exhaust back box
6. Remove DPF.

Installation is the reverse of removal; the main issue is the cost of the DPF itself, which is considerable.

The most common 2.0 Ingenium models we are seeing with DPF failure are the L538 Evoque and the Discovery sport and the following parts required for these models:

• LR134916 – Diesel Particulate Filter
• LR081471 – Exhaust Pipe Gasket

PLEASE NOTE: the above fitting instructions are for Discovery Sports and Range Rover Evoques up to 2019. Later vehicles have a different DPF unit that has a Particulate Matter Detection sensor and in our experience, around 75% of these will seize in the DPF and need to be cut out and replaced with a new one so always have one ready if you’re going to do the job.

This estimate is for the replacement of the Diesel particulate filter and gasket on the Range Rover Evoque and Discovery sport 2 litre models and is inclusive of Labour and VAT. Please be advised that should any additional gaskets or components be required, this price would be subject to change.
