Land Rover Discovery 5 air suspension compressor
,L462 AMK air compressor pump
,automotive air suspension pump with warranty
The LR083993 is an original-equipment-grade air suspension compressor pump developed specifically for the Land Rover Discovery 5 (L462) and multiple same-platform models, manufactured by AMK. This component serves as the core power source for the vehicle's air suspension system, responsible for continuously supplying high-pressure compressed air to the air springs to maintain the standard ride height and driving stability, while also supporting Land Rover's renowned balance of all-terrain off-road capability and on-road ride quality.
As one of Land Rover's original equipment suppliers for this component, AMK manufactures this compressor pump to strict OE standards, fully complying with Land Rover's original design requirements in terms of material selection, manufacturing precision and durability testing. This product is supplied as the compressor core assembly, installed in the vehicle's underbody area. During installation, the original vehicle's air intake lines, mounting bracket and electrical connector must be reused, or a complete assembly version with bracket and relay can be chosen to simplify the installation process.
When the original compressor suffers performance degradation due to system leaks, prolonged wear or electrical faults, this brand-new AMK unit represents the most reliable replacement solution for restoring the air suspension system to full working order. For a large SUV like the Discovery 5 with a kerb weight exceeding 2 tonnes, the compressor operates under sustained high load and is considered a wear-and-tear component.

- Genuine OE Quality: AMK is one of the OE manufacturers of Land Rover air suspension compressor pumps. Quality is identical to the Land Rover Genuine Part.
- Plug-and-Play Installation: Features a pre-assembled complete assembly design, including mounting bracket and relay (depending on version), enabling quick and non-invasive installation.
- Integrated Air Dryer: Comes standard with a maintenance-free integrated air dryer that effectively removes moisture from the compressed air, preventing internal corrosion within the air lines and extending the service life of the entire air suspension system.
- Thermal Overload Protection: Built-in thermal overload protection automatically cuts power when the compressor operates continuously for an extended period or detects abnormally high temperatures, protecting the motor from permanent damage.
- Anti-Corrosion Finish: Features epoxy-coated bracket and other anti-corrosion treatments, effectively resisting corrosion in harsh underbody environments.
Keep dry, clean and handle with care.

Typical failure symptoms include: the vehicle settling after parking, failing to maintain standard ride height; the compressor operating with unusually loud noise or running continuously without switching off; a suspension system warning appearing on the instrument cluster; and a noticeably bumpy ride that loses the expected air suspension comfort.
Before replacing the compressor, you must first check the air springs and air lines for leaks - if the system has a leak, replacing the compressor pump alone will not fundamentally solve the problem, as the leak will cause the new pump to fail prematurely due to continuous overload operation.
Both are OE numbers for Land Rover air suspension compressor pumps and are applicable to the same models. LR140034 is a newer OE number revision, with some aftermarket brands (such as Arnott) covering both numbers in their products. In practice, they are interchangeable, but it is recommended to verify the original part number before installation to ensure a perfect match.
Air leaks are the most common cause of compressor pump failure in Land Rover air suspension systems. It is recommended to thoroughly inspect the air springs, valve block and air lines for leaks when replacing the compressor pump, to prevent the new pump from prematurely failing again due to air leaks elsewhere in the system. Some complete assemblies (such as Arnott P-5166) include a relay for a one-time complete replacement.
