AMK A1991 — Air Suspension Compressor
Overview
Air suspension compressor AMK A1991 supplies pressurized air to the suspension air springs and storage reservoir to control vehicle ride height. Operating at 12 V DC, this unit generates up to 18 bar working pressure and features an integrated silica gel air dryer to prevent moisture build-up inside the system pneumatic lines. It maintains vehicle level during varying road conditions and changes in load capacity. Constructed with a cast aluminium body, the assembly includes a heat-resistant PTFE piston seal and factory-spec 4-pin wiring connector for direct fitment. OEM cross-reference part numbers include LR023964, LR044016, LR045251, LR061663, LR072537, LR078650, and AH223B484AC.
This air suspension compressor fits Land Rover Discovery 3 L319 (2004–2009), Land Rover Discovery 4 L319 (2009–2016), and Range Rover Sport L320 (2005–2013) models. Replacement is required when the unit experiences piston ring seal degradation, electric motor overheating, solenoid release valve failure, or severe moisture overload. Typical fault symptoms comprise extended chassis lifting times, continuous motor running, loud operational noise, or air suspension warning messages displayed on the main dashboard panel. Replacing a failing compressor restores normal system self-levelling function, correct vehicle clearance, and overall ride stability under heavy load conditions.
