Land Rover Turbo and Actuator Repair — Find Your Engine First

Land Rover kept its model names in production while the diesels underneath them changed, so our Land Rover pages are divided by engine rather than by model. Two lines from your logbook and the label on the unit are all it takes to reach the right one.

Which Land Rover Engine Do You Have?

Three facts take you to the right page, and the first two are on your V5C.

1. The engine capacity. Section P.1 gives it in cubic centimetres. It narrows the table below to one or two rows before the model is even considered, and at the two changeovers above it is the one quick check that cannot be misread.
2. The model. Where two engines share a size, the model separates them. A 2.2 Defender has Ford’s Puma engine, while a 2.2 Freelander 2, Evoque or Discovery Sport has the engine those three cars share, and the two take different turbochargers.
3. The label on the unit. Once the turbocharger or actuator is off, the reference on its housing confirms what it is. Photograph it before anything is cleaned or packed. If it is missing or burnt off, send the unit anyway: we identify it on the bench before any work starts.

The years are those given in the parts listings each page is built from. Where a model appears in two rows with overlapping years, the capacity on the V5C decides the row.

Land Rover diesels without a page of their own

Some Land Rover diesels are not covered by any of the pages above: the 3.6 TDV8 and 4.4 SDV8 V8s in the Range Rover and Range Rover Sport, which run pairs of turbochargers, the BMW-based 3.0 diesel in the earlier Range Rover L322, and the original Freelander’s 2.0. The same applies to petrol Land Rovers. Complete the online Repair Form with the reference from the turbo’s label and your registration, and we can tell you what the unit is and whether it is a candidate for a rebuild before you post anything.

The 2.2 Diesel: Freelander 2, Evoque and Discovery Sport

One 2.2 diesel, badged TD4 or SD4, sits in the Freelander 2, the first-generation Range Rover Evoque and the Discovery Sport. The Evoque and Discovery Sport were only ever listed with the later of its two turbochargers. The Freelander 2 was built with both, and the years around 2010 do not separate them cleanly.

Our Freelander 2, Evoque and Discovery Sport turbo repair page covers the turbocharger on all three cars, including how to tell the early unit from the later one. If the fault is in the electronic actuator on the side of the turbo, the Freelander 2 turbo actuator repair page covers both actuator types.

A Discovery Sport or Evoque from 2015 or 2016 may have the 2.0 Ingenium instead, which neither of those pages covers. A 2.2 on the V5C keeps you on them; a 2.0 sends you to the Ingenium section below.

The TDV6 2.7 and 3.0: Discovery and Range Rover Sport

Land Rover sold two TDV6 diesel V6s, and the Discovery and the Range Rover Sport each carried both in turn. Their turbochargers are catalogued under entirely different references, so the capacity comes first here too.

• 2.7 TDV6: listed in the Discovery 3 from 2004 to 2010 and the Range Rover Sport L320 from 2005 to 2010. We rebuild its turbocharger through two listings, one for the Discovery 3 2.7 TDV6 and one for the Range Rover Sport 2.7 TDV6.
• 3.0 TDV6 and SDV6: catalogued for the Discovery 4 and Range Rover Sport from 2009, then for the Range Rover L405 and Range Rover Sport L494. The twin-turbo versions carry two turbochargers that are not spares for each other, and our Range Rover and Discovery 4 3.0 TDV6 turbo repair page explains how they are catalogued and how to tell which one has failed.

The electronic actuators from the Discovery 3, Discovery 4 and Range Rover Sport are covered on our Discovery and Range Rover Sport TDV6 actuator repair page, which also shows how to confirm at the car whether your actuator is electronic at all.

The 2.0 Ingenium Diesel

The 2.0 Ingenium four-cylinder diesel took over from the 2.2 in the Evoque and Discovery Sport from 2015, and runs through most of the later range: the Velar, the Discovery 5 and the 2020-on Defender, as well as several Jaguars. Depending on its output, it carries either one turbocharger or a high-pressure and low-pressure pair.

Our Ingenium 2.0 diesel turbo repair page covers both layouts. Read it before the turbo comes off, because on this engine the checks your garage makes on the engine decide whether a rebuilt turbo is worth fitting.

The Defender: Tdi, Td5 and Puma Engines

The Defender built until 2016 carried several diesels under a body that barely changed: the 2.5 Diesel Turbo, the 200Tdi and 300Tdi, the five-cylinder Td5, and from 2007 Ford’s 2.4 and then 2.2 Puma engines. The Tdi and Td5 turbochargers are wastegated, and the Puma was the first Defender engine sold with a variable-geometry turbo. Our Land Rover Defender turbo repair page tells the engines apart by cylinder count and bonnet shape, and lists the references UK suppliers give for each.

The Discovery 1 and 2 used the Tdi and Td5 engines, so the Defender page is the place to start for those too. It carries one caution worth knowing in advance: a shared engine was not always installed the same way, so the label on your own unit decides. The 2020-on Defender is a different vehicle, and its 2.0 diesel is covered in the Ingenium section above.

Electronic Turbo Actuators on Land Rover Diesels

On a variable-geometry turbocharger, boost is set by a ring of vanes inside the turbine housing, moved by an actuator bolted to the outside. Where that actuator is electronic, with a motor, a gear train and a position sensor in a sealed housing, it is a separate part we rebuild on its own, from £100 + VAT and typically in one to two working days. It goes back on without programming.

• Freelander 2, Evoque and Discovery Sport 2.2: two different electronic actuators, one on early Freelander 2 cars and one on later cars, covered on the Freelander 2 actuator page.
• Discovery 3, Discovery 4 and Range Rover Sport TDV6: covered on the TDV6 actuator page, which explains how to tell an electronic unit from a vacuum-worked can with the engine cold.
• 2.0 Ingenium: actuator wear is reported on this engine, but it has no actuator page of its own. Send the reference from the label through the Repair Form.
• Tdi and Td5: not electronic. These turbos are wastegated, with an actuator can on the side of the unit, and our wastegate actuator repair page explains why the setting of its rod matters as much as the can itself.
• 2.4 and 2.2 Puma: send the turbocharger with its boost-control hardware attached, exactly as it came off, as the Defender page sets out.

Every electronic actuator we rebuild, across every make, is listed on our electronic turbo actuator repairs page.

Turbo or Actuator? Which Page You Need

On a variable-geometry Land Rover the two parts share several symptoms, so the turbo often gets blamed for an actuator fault and the other way round. Three observations usually decide which page to read.

• Oil smoke, oil in the intake pipework, or a whine that rises and falls with engine speed points at the turbocharger itself, usually worn bearings or seals. Use the turbo page for your engine.
• Actuator or boost-position fault codes, with a power cut that a restart sometimes clears, point at the actuator. On a Freelander 2 this often appears as “Performance Restricted” in the instrument cluster. Use the actuator page.
• A flat engine with no code stored points at neither until the intake pipework has been checked, because a split hose or a slipped clamp loses boost in exactly the same way.

Where the vane lever can be reached, one hand check separates the two parts. With the actuator disconnected, a lever that sticks, catches or stops short means the fault is inside the turbocharger, and a lever that sweeps freely puts the actuator back under suspicion. The actuator pages explain how to make that check on each engine. For the full symptom maps, see our guides to turbo failure symptoms and turbo actuator symptoms.

Sending your unit in

1. Tell us about the vehicle. Complete the online Repair Form with the registration, the engine capacity, any fault codes and a photograph of the unit’s label.
2. Send the turbo complete. Leave its actuator or wastegate can attached. If only an electronic actuator is being repaired, the actuator alone comes to us.
3. Pack and post it. Seal every oil and air opening, pack the unit in a rigid box, and post it to Unit 102 Reaver House, 12 East Street, Epsom, Surrey, KT17 1HX, United Kingdom. Our FAQs cover packing and postage.
4. We identify, strip and report. The unit is matched to your engine, stripped and measured, and we tell you what we found before the rebuild goes ahead.

Independent garages and main dealers send units in the same way owners do.

Land Rover Turbo Repair FAQ

Final Thoughts

A Land Rover turbo search covers a long run of diesel engines under a handful of model names that outlived several of them. The capacity on your V5C and the model narrow that to one page, the changeover years included, and the label on the unit confirms it.

The decision after that is turbocharger or actuator, and it is worth settling before anything is unbolted. Oil and noise point at the turbo; stored codes and a fault that clears on a restart point at the actuator. Either way, the page for your engine takes it from there.
