2025 IM6 Performance ride height concerns: distinguish air suspension from CCD

After parking an Australian 2025 IM6 Performance, the owner notices a different body height and immediately asks whether a shock absorber needs replacing. Distinguishing air suspension height adjustment from CCD damping control helps match inspection and procurement to the correct item.

Check which height function was used

MG Australia's MY25 brochure confirms air suspension and CCD for IM6 Performance. It describes lowering the body for entry, exit and luggage access, and raising ground clearance.[Manufacturer equipment and function description][T05]

When height changes, first establish when it happened and whether a corresponding function was used. Record function-related adjustment separately from an owner's report that one corner dropped after the vehicle stood for some time. A photograph taken just after parking cannot replace a leak check.

Height and damping describe different concerns

In general suspension principles, springs and shock absorbers perform different tasks. Shock absorber damping controls spring oscillation and limits continued bouncing.[KYB general principle][T14] “The body is lower” and “it keeps moving after a bump” describe different observations. They should not both be reduced to “failed air shock”.

At intake, record body height changes, the sensation after road bumps and instrument warnings separately. For procurement, specify whether the item being checked relates to air suspension or damping components with electronic control. How they form supply assemblies on this vehicle still requires a parts catalogue check. [To be verified]

Retain comparable observations before selecting an area to inspect

For a report of “it drops overnight”, useful details include which corner, how long it stood, whether the surface was level, the load and modes used. If the main concern is changed ride behaviour, record road conditions and warnings. This organises observations; it does not set an owner test acceptance limit.

The technician should locate the concern using inspection findings for this vehicle before defining replacement scope. Equating a height concern directly with CCD failure, or a changed ride impression with failure of the entire air suspension, omits the necessary diagnostic evidence.

Scope and verification

This article covers only Australian MY25 IM6 Performance 100kWh AWD. The brochure narrative and equipment table differ on the optional status for Platinum; this article therefore uses only Performance, which both confirm. [To be verified] KYB material explains general damping principles only and does not establish KYB supply to IM6 or product fitment. [To be verified]

No public data was available in the reviewed material for permitted settling, test pressures, leak standards, CCD fault codes or electrical limits, separate pump/valve and air spring availability, OE numbers or repair parameters. [To be verified] Check compatibility or interchangeability using the VIN and the local Australian manufacturer parts catalogue.
