Why does my Range Rover keep showing a suspension fault?

Short answer: The L322 Range Rover's air suspension fault can be from a weak battery, an air leak, or a tired compressor. Owners have found a pinhole leak in the air tank when shops quoted struts and a compressor. Charge the battery, find leaks, check the compressor filter.

Symptom: A message about the suspension, the car sitting low, compressor running often or getting hot.

What to check first

1. Charge the battery. An owner said 12.2 volts is weak; you want 12.6.
2. Clear codes with a good battery.
3. Check for leaks with soapy water at the reservoir, valve blocks and dryer cap.
4. Check the compressor exhaust filter. A clogged one makes the compressor overwork.

Likely causes

1. Air leak (tank, valve block, struts).
2. Weak battery.
3. Worn compressor. Rebuild kits exist.

What it usually costs

A shop quoted an owner about $1,700 for front struts and $1,000 for a compressor; the actual fault was a pinhole leak in the reservoir tank.

Is it safe to keep driving?

If it sits at normal height, yes for short trips. If it's stuck low, drive slowly. Verify with a mechanic.

DIY or shop?

DIY for battery and leak checks. Release pressure first.

What owners report

• In Compressor woes on LandyZone, a 2008 owner was quoted about $1,700 for front struts and $1,000 for a compressor, but the leak was a pinhole in the reservoir tank. Members said 12.2 V is a weak battery.
• In Air suspension faults on LandyZone, members said a clogged compressor exhaust filter makes it overheat and to clear codes with a charged battery. They noted a change to a Hitachi compressor around 2006–2007.

Quick tip

Don't let anyone sell you struts before checking for leaks.

Vehicle focus: 2003–2012 Land Rover Range Rover (L322). The Range Rover Sport is a different vehicle.

Safety / mechanic note

A sagging air suspension can change handling and headlight aim, and a car that drops to the bump stops can damage tires and parts. Verify with a mechanic.
