,G31 air suspension pump with warranty
The 37206886721 is an original-equipment-grade air suspension compressor pump developed specifically for the BMW G31 5 Series Touring and G32 6 Series Gran Turismo, manufactured by Wabco. This component serves as the core power source for the vehicle's rear-axle air suspension system, responsible for continuously supplying high-pressure compressed air to the rear air springs to maintain the standard ride height and driving stability.
As one of BMW's original equipment suppliers for this component, Wabco manufactures this compressor pump to strict OE standards, fully complying with BMW'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 rear area of the vehicle. During installation, the original vehicle's air intake lines, mounting bracket and electrical connector must be reused.
When the original compressor suffers performance degradation due to system leaks, prolonged wear or electrical faults, this brand-new Wabco unit represents the most reliable replacement solution for restoring the rear air suspension system to full working order.

| Question | Answer |
|---|---|
| Q1: How can I tell if my G31/G32 air suspension compressor pump needs replacement? | Typical failure symptoms include: the rear of the vehicle settling noticeably after parking, failing to maintain standard ride height; the compressor operating with unusually loud noise or running continuously without switching off; a "Chassis System" warning appearing on the instrument cluster; and a noticeably bumpy rear ride that loses the comfort expected from self-levelling suspension. 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. Some owners have reported that compressor failure may also be caused by wiring wear or relay faults, so it is recommended to check electrical issues first. |
| Q2: Which models is this compressor pump compatible with? | This product is compatible with all BMW G31 5 Series Touring (2017–2022) and G32 6 Series Gran Turismo (2017–2022) models equipped with rear-axle air suspension, covering various powertrain configurations including 518d, 520d, 520i, 530d, 530i, 540i, M550d and others. Please note: This product is not suitable for models equipped with steel spring rear suspension. |
| Q3: Should I replace other components at the same time as the compressor pump? | It is recommended to inspect the air springs 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 aftermarket complete assemblies (such as Arnott) include a relay for a one-time complete replacement. If wiring wear or relay faults are present, these should also be addressed at the same time. |
