Land Rover Range Rover Sport: Air Suspension Corner Valve Block Failure
Air Suspension Corner Valve Block Failure is a common suspension fault on the Land Rover Range Rover Sport on the 2013–2022 cars, and we rate it major. Putting it right costs $1,800 to $4,000 at New Zealand independent workshop rates. Below is what goes wrong, the symptoms to notice on a test drive, where to look, and what to ask the seller before you hand over any money. It is one of 25 documented faults on the Land Rover Range Rover Sport.

What goes wrong
The L494 air suspension uses a central valve block with individual solenoid valves for each corner. The internal seals degrade over time, allowing air to bypass a closed solenoid and creating a slow corner-specific leak. The compressor compensates by cycling more frequently, accelerating its own wear. A failed valve block causes one corner to sag even when the compressor operates normally. The valve block assembly typically requires replacement as a unit because individual seal repair is not practical.
What you would notice
- A single specific corner sagging even after the compressor has run
- Compressor cycling very frequently to maintain ride height
- Air suspension fault code for a specific corner on diagnostic scan
- Gradual overnight sag isolated to one corner only
How to check it
Where to look. Air suspension valve block, typically mounted in the engine bay near the front suspension
Park overnight and check whether sagging is at a specific corner (valve block likely) versus general sag across multiple corners (compressor or struts).
Scan for corner-specific height sensor and solenoid valve fault codes.
Inspect the valve block housing for oil or moisture contamination ingress.
What it costs to put right
$1,800 to $4,000 at New Zealand independent workshop rates. That is for this job on its own, not for the car.
Ask the seller
- “Has the air suspension valve block been replaced?”
- “Does any specific corner sag more than others?”
- “Have there been air suspension fault codes specific to one corner in the history?”

Land Rover Range Rover Sport buyer questions
Is air suspension corner valve block failure serious on a Land Rover Range Rover Sport?
We rate it major and common on the Land Rover Range Rover Sport. The L494 air suspension uses a central valve block with individual solenoid valves for each corner. The internal seals degrade over time, allowing air to bypass a closed solenoid and creating a slow corner-specific leak. The compressor compensates by cycling more frequently, accelerating its own wear. A failed valve block causes one corner to sag even when the compressor operates normally. The valve block assembly typically requires replacement as a unit because individual seal repair is not practical.
How much does it cost to fix on a Land Rover Range Rover Sport?
$1,800 to $4,000 at New Zealand independent workshop rates. That figure is for this job on its own. A car showing the symptoms on this page is usually worth either walking away from or negotiating down by at least the repair figure.
Which Land Rover Range Rover Sport years are affected?
Our research records this fault on the 2013–2022 Land Rover Range Rover Sport. Build dates move around, especially on imported cars, so treat the range as the years to look hardest at rather than a guarantee either way. The official records tell you the exact build and first registration date for the car in front of you.
How do I check for it before I buy?
Park overnight and check whether sagging is at a specific corner (valve block likely) versus general sag across multiple corners (compressor or struts). Scan for corner-specific height sensor and solenoid valve fault codes. Inspect the valve block housing for oil or moisture contamination ingress.
