Why is my Range Rover Sport air suspension sagging?

Short answer: A Range Rover Sport that sags overnight usually has a leaking air spring or valve block, not just a bad compressor. Find the leak first. The compressor often fails after it has been working overtime.

Symptom: One corner or one end sitting low after parking, a suspension warning, a harsh ride, or the compressor running constantly.

What to check first

1. Note which corner is low after the SUV sits overnight.
2. Listen for the compressor running a long time after you start the vehicle.
3. Ask the shop to leak-test the springs and valve block before they replace the compressor.
4. Scan for air-suspension codes.

Likely causes

1. A leaking air spring (air bag). If the Sport drops overnight, especially on one corner, an air spring is often leaking. The compressor only runs with the vehicle awake, so a car that sags while parked is leaking down, not just 'a dead compressor.'
2. Valve block or air lines. If both sides of one end drop, or several corners go down, the valve block or a line may be leaking. A soapy-water check at the springs and fittings helps find bubbles.
3. Compressor failure after it works too hard. A compressor can overheat or fail from pumping up a leak all the time. Replacing only the compressor without fixing the leak often means another failure later.

What it usually costs

Air-spring or compressor replacement is a significant shop job. The 2011 thread mentioned a low purchase price, not a repair bill we can treat as typical for a 2018–2022, so we are not inventing a number.

Is it safe to keep driving?

You can usually drive slowly to a shop if the SUV is not scraping. Riding on the bump stops hurts tires and other parts, so do not take a long trip that way.

DIY or shop?

A soapy-water leak check is DIY if you can get under it safely. Replacing springs or the compressor is a shop job for most owners.

What owners report

• In 2018 Range Rover Sport Air Suspension Replacement on Reddit r/RangeRover, a 2018 Range Rover Sport owner posted about an air-suspension replacement and asked others about parts and the job.
• In Auto access feature is switched off on my RR Sport 2020 . But when I park the car and come back to it I find the passenger side tilted down compared to driver side. Once the car is switched on it auto starts rising up. on Reddit r/RangeRover, a 2020 Range Rover Sport owner said the passenger side sat lower after parking even with the auto-access feature off, then the SUV rose again after it was started — the classic leak-down pattern.

Quick tip

Look at a parked Sport first thing in the morning. A lean to one corner is a leak until proven otherwise.

Safety / mechanic note

A SUV sitting on its bump stops handles and brakes worse. Verify with a mechanic.
