2013 Audi S6 Air Suspension Compressor Part Number: Complete Guide

If you own a 2013 Audi S6 and your air suspension system is failing, the compressor is often the culprit. This guide provides the correct OEM part numbers, aftermarket alternatives, and practical advice for sourcing a replacement. Whether you’re a DIY mechanic or working with a shop, having the exact part number ensures you get the right component the first time.

OEM Part Numbers for the 2013 Audi S6 Air Suspension Compressor

The original equipment compressor from Audi is the most reliable choice. For the 2013 S6, the primary OEM part number is 4G0 616 007 D. This compressor is also used on other Audi models with air suspension from the same era. Always verify that the part number ends with "D" – earlier revisions (A, B, C) may not be direct replacements. Make sure to check your vehicle’s production date; very early 2013 models might use a different suffix. Cross-reference your VIN with a dealer parts department to confirm.

Alternative OEM Compressors

Audi also lists a remanufactured version under part number 4G0 616 007 DX. This is a factory rebuild that is often cheaper than a brand new unit but still meets OEM specifications. If your compressor failed due to an electrical issue (common on these cars), a reman unit may be a cost-effective solution.

Aftermarket Compressor Options

Several reputable brands manufacture direct replacement compressors for the 2013 Audi S6. These are often identical to the OEM part but sold without the Audi logo. The most common aftermarket part numbers are:

• Pierburg 7.22604.79.0 – Pierburg is the original manufacturer of the compressor for Audi. This is essentially the same unit as OEM, but often priced lower.
• Hella 8HV 007 378-121 – Hella’s offering is another high-quality alternative that matches OEM specs.
• Arnott P-3747 – Arnott specializes in air suspension components and their compressors are popular in the aftermarket. They include a new dryer and valve block in many kits.

When buying aftermarket, ensure the compressor includes the integrated pressure sensor and electrical connectors. Some cheap knockoffs omit these, causing installation headaches. Stick with known brands to avoid premature failure.

Key Considerations Before Buying

Compatibility with Your Vehicle

Not all compressors labeled for "2013 Audi S6" are identical. The S6 uses a four-corner air suspension system (adaptive air suspension). Some compressors may be shared with the A6 or A7, but the S6’s compressor has a specific pressure output and valve setup. Always compare the new compressor’s mounting bracket and electrical plug shape to the old one.

The Integrated Dryer and Valve Block

The compressor unit includes a desiccant dryer and an exhaust valve. On the 2013 S6, the dryer is built into the compressor housing. When replacing the compressor, it’s smart to replace the dryer as well, but it only comes as part of the compressor assembly. For OEM units, the dryer is integrated; some aftermarket brands offer a separate dryer replacement kit. If you buy a compressor without a dryer, you risk moisture contamination in the system.

Common Failure Signs

A failing compressor on a 2013 S6 typically shows these symptoms:

• Air suspension warning on the dash
• Vehicle sags after sitting overnight
• Compressor runs continuously or cycles too often
• Loud grinding or buzzing noise from the compressor (located under the hood, driver side)
• "Air Suspension Fault" error codes like P1434 or P1435

If you have these symptoms, check the compressor first, but also inspect the air struts and lines for leaks. A leaking strut can overwork the compressor and cause it to fail prematurely.

Step-by-Step Replacement Overview

While this is not a full repair manual, here’s a high-level overview for a DIY replacement. For safety, discharge the air system by opening the valve at the compressor (or use a scan tool).

1. Disconnect battery negative terminal. The compressor has power even with the car off.
2. Remove underhood trim if needed. The compressor is located in the driver side front cowl area, behind a plastic cover.
3. Disconnect electrical connector and air lines. Mark the lines to avoid mixing up supply and exhaust ports.
4. Remove mounting bolts (typically 10mm or 8mm).
5. Install new compressor using new sealing washers on the air line fittings. Torque to spec (around 7 Nm for line nuts).
6. Reconnect battery and run a calibration routine using a scan tool like VCDS. This tells the car the new compressor is installed and sets the ride height positions.
7. Test the system by raising and lowering the car through the suspension settings.

If you don’t have a scan tool, the system may still work but the ride height may be off. Many independent shops can perform calibration for a small fee.

Cost and Where to Buy

OEM compressor (4G0 616 007 D): $700–$1,200 new, $400–$600 remanufactured. Aftermarket alternatives: $300–$600.

Because air suspension repairs are expensive, many owners opt for aftermarket compressors. Pierburg and Hella are factory suppliers, so their units are identical in quality. Arnott offers a lifetime warranty on some compressors. Always check the warranty terms – some require professional installation.

When buying, avoid no-name parts on unknown websites. Stick with trusted auto parts retailers, or your local Audi dealer for OEM. If you need to save money, the Pierburg unit is the best balance of price and reliability.

Final Recommendation

For a 2013 Audi S6, the safest bet is the OEM compressor part number 4G0 616 007 D or its remanufactured version 4G0 616 007 DX if you want to stay factory. If you want to save without compromising quality, use the Pierburg 7.22604.79.0 – it’s the same part as OEM without the Audi branding. Avoid compressors that do not include the integrated dryer and sensor. Finally, always diagnose the entire system before replacing the compressor, as a leaking strut will kill the new compressor quickly. With the right part and proper installation, your S6’s air suspension will ride smoothly for years to come.
