Description
About the Audi A6 Air Suspension
The Audi A6 is Audi’s mid-size luxury sedan and wagon platform, and air suspension is fitted to certain trims across multiple chassis generations. Most common air-suspended A6 trims are the A6 Allroad (which uses raised air suspension with multiple height settings for light off-road capability), the Sport package A6, the high-performance S6, and the supercharged RS6. Standard A6 sedans typically use coil suspension, so air suspension components only fit specific trims.
Audi A6 Chassis Generations Carrying Air Suspension
| Generation | Details |
|---|---|
| C5 Allroad (2000 to 2005) | First Audi Allroad. 4-corner air suspension with multi-level height adjustment. Famously failure-prone past 100,000 miles, very strong aftermarket support. |
| C6 Chassis (2005 to 2011) | A6 Sport package, S6, RS6 with adaptive air. C6 Allroad continued in some markets but was not US-market. |
| C7 Chassis (2012 to 2018) | A6 Sport package, S6 with adaptive air. C7 Allroad sold in some markets. |
| C8 Chassis (2019 to 2024) | A6 Allroad returns to US market with full air suspension. S6 and RS6 also use air. |
Common Reasons to Replace Audi A6 Air Suspension Components
- Air spring leak (most common A6 failure, especially on the C5 Allroad)
- Compressor burnout from continuous run on a leaking system
- Compressor relay failure (cheaper fix)
- Valve block O-ring leak
- Height sensor wiring corrosion or failure
- Compressor air dryer saturation, moisture damaging downstream components
A6 Air Suspension Components We Carry
- Front air struts (with adaptive damper integrated where applicable)
- Rear air springs (separate from shocks on most A6 chassis)
- Air compressor with integrated dryer
- Compressor relay and harness
- Valve block (manifold valve)
- Height sensors and harness
- Air lines and fittings
- Complete air suspension kits
A6 Allroad Specific Notes
The A6 Allroad uses a more capable air suspension than standard A6 trims, with a wider range of ride heights to support light off-road driving. Allroad components are not interchangeable with regular A6 air suspension components, so always confirm Allroad trim at order. The Allroad is also the most common A6 air suspension failure platform because its ride height adjustment cycles wear the air springs faster than in the lower A6 sedan.
What Ships and What Does Not

| NOT INCLUDED | Diagnostic scan tool (you will need a VAG-COM or VCDS to run module adaptations after install on most components), wheel alignment (always required after suspension work), tools. |
| Tools You Need | Standard hand tools, spring compressor (front struts), torque wrench, jack and stands or lift, VCDS or equivalent diagnostic scan tool for module adaptations, alignment shop visit after install. |
Direct-Fit Vehicle Applications
Audi A6 air suspension components are compatible with the following:
| Vehicle | Compatibility |
|---|---|
| Audi A6 Allroad C5 | 2000 to 2005 (4B body code) |
| Audi A6 Sport / S6 / RS6 (C6) | 2005 to 2011 (4F body code) |

NOT compatible: standard coil-suspended A6 sedan trims that did not come with air suspension. Always confirm air-equipped trim before ordering.
Quality Control Workflow
These are new Audi A6 air suspension components in OEM specification. Quality control includes:
- Pressure test on every air strut and air spring before packaging
- Compressor cycle test under simulated load
- Valve block leak test
- Adaptive damper electrical continuity check (where applicable)
- Height sensor calibration check
- Mounting hardware fit verification
These are new components, not used. We do not sell used air suspension components.

The Allroad uses ride height adjustment that cycles the air springs much more frequently than a standard A6 sedan does. Each height change requires the springs to inflate and deflate, which wears the rubber bladder over time. The C5 Allroad (2000 to 2005) is particularly known for air spring failure past 100,000 miles. The aftermarket has very strong support for C5 Allroad air suspension repair and conversion.
Ride height range and component spec. The Allroad has a wider range of ride heights to support light off-road driving, requiring different air springs with greater extension capability. Allroad components are not interchangeable with standard A6 air suspension. Always confirm Allroad trim when ordering.
By chassis generation: C5 Allroad (2000 to 2005), C6 A6 Sport package, S6, and RS6 (2005 to 2011), C7 A6 Sport package and S6 (2012 to 2018), C8 A6, A6 Allroad, and S6 (2019 to 2024). Standard A6 sedan trims without Sport package typically have coil suspension. Confirm air-equipped trim before ordering.
New. We do not sell used air suspension components because used air struts have unknown remaining service life. All components are new OEM-specification from established manufacturers including Arnott, Bilstein, and Continental.
For most components, yes. After installing air struts, height sensors, or the valve block, the system typically needs module adaptation in VCDS (or equivalent VAG-COM tool) to recalibrate ride height and confirm component operation. Plan for VCDS access at installation.
Yes. The C5 Allroad coil conversion is one of the most well-established VW/Audi aftermarket conversions. Multiple suppliers offer complete conversion kits that replace all four air struts and springs with coil-over assemblies, while bypassing the air system electronics. The conversion eliminates air spring repair cycles forever, at the cost of losing the height adjustment feature. Many aging Allroad owners ultimately opt for conversion.
Damper calibration and spring rates. The S6 uses adaptive air with a sport-tuned calibration. The RS6 uses a stiffer air suspension calibration designed for the higher-performance application. Specific spring and damper components are RS6-specific and not interchangeable with regular S6. Confirm trim when ordering.
Variable by chassis and components. For a C5 Allroad, complete four-corner air strut refresh plus compressor and valve block can run $1,800 to $3,500 in parts plus 4 to 8 hours of labor. For a newer C8 A6 Allroad, costs are higher due to component complexity. We provide complete-kit pricing on request, which typically delivers labor savings versus piece-by-piece repair.

Kurt L. –
Got a pair of front air struts for a 2004 A6 Allroad C5. Chassis generation confirmed (C5 Allroad, not regular A6), corner locations verified, pressure-tested before packaging. Plan VCDS module adaptation at install. Foundation for getting the Allroad back to factory ride height.
Sandra R. –
Sourced a complete air suspension kit for a 2017 A6 Sport. Chassis generation confirmed as C7, trim verified as Sport package (not standard coil). Adaptive damper compatibility for the year confirmed. Honest about the VCDS adaptation requirement at install. Components from established supplier as advertised.
