Product Identity

The Unity 20-025002 is a new air suspension compressor designed to restore the rear levelling function on specific BMW models. It is manufactured by Unity Automotive, a company with over 50 years of aftermarket experience specialising in suspension components.

Fitment Guidance

This compressor fits 1996 to 2006 BMW 520i, 523i and 528i models, as well as the 2000 to 2006 BMW X5 equipped with rear levelling only. It is not suitable for vehicles without rear air suspension or for X5 models with four-corner air suspension systems.

Installation Notes

The unit is built to OE specifications for a trouble-free installation, though the supplier provides no torque values, wiring diagrams or adapter details. Common issues include reusing old air lines or fittings, which can introduce leaks, and failing to address the root cause of the original compressor failure such as a leaking air spring.
