What goes wrong
The Discovery 5 carries over full air suspension and the same ownership reality: compressors wear, valve blocks and air lines leak, and height sensor faults throw 'suspension fault' warnings, with cars sagging overnight as they age past 5-7 years. It is less failure-prone than the D3/D4 era but is now the most common D5 complaint on owner forums as the fleet ages. Repairs at NZ independent Land Rover specialists are routine but not cheap.
What you would notice
- 'Suspension fault' or 'normal height only' warnings
- Vehicle sat low on one corner after parking
- Compressor running longer/louder than normal
- Slow height changes
How to check it
Where to look. Compressor and valve block under the vehicle, air springs at each corner
Check the stance on arrival before the car is started.
Cycle through all ride heights and time the rise.
Listen for the compressor continuing to run after height is reached (indicates a leak).
Ask for any suspension repair invoices and scan for stored suspension fault codes at a pre-purchase inspection.
What it costs to put right
$700 to $2,200 at New Zealand independent workshop rates. That is for this job on its own, not for the car.
Ask the seller
- “Any suspension fault messages or compressor replacement history?”
- “Does it sit level after being parked for a few days?”
