2.0 Ingenium Turbo Failure

The 2.0 Ingenium diesel engine is widely used across the Jaguar Land Rover range, but unfortunately, turbocharger failure is a known and relatively common issue. The causes range from poor oil quality and contamination to carbon build-up or outright failure of related components like the oil feed pipe.

This guide covers the typical symptoms of turbo failure, the causes, and the steps involved in replacing the turbocharger on the 2.0 Ingenium Diesel engine.

For background on why these turbos fail, please also see our detailed Turbo Failure Common Faults page.

Turbo failure on the 2.0 Ingenium is often related to oil starvation or contamination. In many cases, this stems from:

• A blocked or restriction in the turbo oil feed pipe
• Fuel dilution of engine oil, often from failed or incomplete DPF regens
• Long oil change intervals, degrading oil quality over time
• Carbon or sludge build-up, particularly if the car is mainly used for short trips

It’s not uncommon to find turbos failing shortly after a timing chain or DPF-related fault — which highlights the importance of routine servicing and early intervention.

We always recommend inspecting the turbo oil feed pipe. If this is blocked, simply replacing the turbocharger unit without addressing the blockage will likely result in the premature failure of the new unit.

Replacing the turbo on the 2.0 Ingenium diesel is a relatively involved job due to tight access around the engine and the fact that critical fixings will have been through many heat cycles and are likely to be frozen in place

Step-by-step summary:

1. Remove engine cover, scuttle panel, and firewall
2. Remove airbox and boost hose
3. Disconnect and remove the EGR valve
4. Remove the turbo oil feed and oil drain pipes
5. Remove turbo heat shields and exhaust support bracket
6. Undo the 3x 13mm turbo-to-manifold nuts and remove the turbocharger
7. Clean mating surfaces, flush out all lines and fit new gaskets, refitting components in reverse order
8. Inspect the intercooler: if any oil contamination from the turbo failing is found, replace it at the same time
9. Replace engine oil and oil filter.

IMPORTANT: If the turbo has failed and sent oil into the intercooler, we strongly recommend replacing the intercooler at the same time Flushing it is rarely effective, and any remaining oil can cause immediate damage to a new turbo.

Part numbers regularly required to replace the turbocharger on the 2.0D ingenium engine:

• LR140581 – Turbocharger
• LR073725 x 3 – Hex Nuts
• LR073671 x 4 – Copper Washer
• LR072251 – Turbocharger Gasket
• LR073723 – Exhaust Manifold Gasket
• LR073687 – Sealing Ring
• LR073688 – Sealing Ring
• LR139043 – Intercooler (if required)

This estimate includes removal and replacement of the turbocharger, all necessary gaskets and washers, new engine oil and filter, and inspection of the intercooler, plus labour and VAT.

Please be advised, additional charges may apply if the intercooler or turbo oil feed pipe needs replacement due to contamination or damage. Costs may also vary on transverse engine models vs those with longitudinally mounted engines due to the turbo being on the back of the engine rather than the side.
