Air suspension failure
CAR magazine's buying guide lists air suspension failures that cause a poor ride or a vehicle sagging on one side; compressors, air struts, valves and height sensors are the usual parts.
Range Rover · L494 · 2013–2022
The aluminium-bodied second-generation Range Rover Sport, sold in South Africa from 2013 with SDV6 and SDV8 diesels and supercharged petrol engines.
Each system page explains what is specific to the Range Rover Sport (L494) before you narrow down to the part.
On the L494, owners most often ask for air suspension parts, turbochargers, water pumps and radiators, oil leak gaskets and seals, and NOx sensors and DPFs for the diesels. Brake discs and pads, front anti-roll bar bushes, drop links and hub bearings are routine chassis orders. Headlights, bumpers and grilles are common after accidents. Give us the VIN and engine, because SDV6, SDV8 and supercharged versions use different parts. When a turbocharger fails, specialists recommend checking and cleaning the oil feed and replacing contaminated parts such as the intercooler and feed pipes, so a turbo enquiry often grows into a small parts list rather than a single item.
The second-generation Range Rover Sport launched in South Africa in 2013 and switched to an aluminium body that shares much of its engineering with the L405 Range Rover. Locally it was sold with the 3.0 SDV6 diesel, the 250kW 4.4 SDV8 diesel and supercharged petrol engines, including the 3.0 SCV6, the 5.0 V8 and the 423kW SVR. Later updates added six-cylinder mild-hybrid petrol engines. Every version uses an eight-speed automatic and adjustable air suspension. Used L494s appear regularly in South African classifieds, and a CAR magazine used-buying guide highlights the areas most owners eventually deal with: electrical and infotainment faults, air suspension failures, oil leaks, turbocharger problems and cooling system components such as radiators and water pumps. The diesels add diesel particulate filters and, from 2016, AdBlue selective catalytic reduction, which bring their own sensor faults. For a parts buyer, the L494 is a vehicle where getting the exact engine right is essential, because SDV6, SDV8, supercharged V6, V8 and later hybrid engines share very little. Suspension parts are closer to the L405 than to the older L320, which is a common source of wrong orders. Send us your VIN and engine designation and we will confirm fitment before quoting.
Engine parts are rarely shared between these units, so quote the engine code or number with every engine-related enquiry.
| Engine | Code / family | Fuel |
|---|---|---|
| 3.0 SDV6 turbodiesel | SDV6 | Diesel |
| 4.4 SDV8 turbodiesel | SDV8 | Diesel |
| 3.0 SCV6 supercharged petrol | — | Petrol |
| 5.0 supercharged V8 petrol (SVR) | — | Petrol |
| 3.0 six-cylinder mild-hybrid petrol (P360, HST; later models) | — | Petrol hybrid |
The faults owners and specialists report most often on this generation, and where to look for the parts involved.
CAR magazine's buying guide lists air suspension failures that cause a poor ride or a vehicle sagging on one side; compressors, air struts, valves and height sensors are the usual parts.
CAR magazine describes oil leaks as a common L494 problem and advises checking seals and gaskets at every service.
Turbocharger failure is named in the local buying guide, and turbo replacement on the diesels is a recognised specialist repair.
Radiators, water pumps and other cooling parts can fail, according to CAR magazine, and should be replaced before overheating damages the engine.
Infotainment screens, dashboard displays and sensors can be faulty; software updates help, but some cases need component replacement.
Diesels from 2016 use AdBlue SCR with sensitive NOx sensors, and all diesels carry a DPF that blocks with short-trip use.
The L494 Range Rover Sport's key maintenance areas are its air suspension, cooling system and, on diesels, the turbocharger and emissions systems. A CAR magazine buying guide advises regular checks of seals and gaskets for oil leaks, timely servicing with high-quality lubricants to protect turbochargers and superchargers, and replacement of cooling components before they cause overheating. Keep infotainment software updated, and on diesels from 2016 keep AdBlue topped up correctly.
CAR magazine's used-buying guide highlights electrical and infotainment faults, air suspension failures that cause a poor ride or sagging, oil leaks, turbocharger and supercharger wear, and cooling system problems with radiators and water pumps. A full service history and a diagnostic scan are strongly recommended.
No. The L494 moved to an aluminium body closely related to the L405 Range Rover, so most suspension and body parts differ from the L320. Ordering by model name alone is a common way to get the wrong part, so send us your VIN.
Send the part name, your VIN and engine number. The SparesBoyz parts team checks fitment for your L494 before quoting.
