Air Compressor/Inflator (Without Valve Assembly) for 2012–2016 Tesla Model S | 6006403-00-ABZC (CFN Brand)

1. Air Supply for Suspension Adjustment: Converts electrical energy into compressed air (output pressure up to 10 bar, consistent with Model S air suspension requirements) to inflate or deflate the vehicle’s four air springs. This enables the suspension to adjust ride height (e.g., raising for rough roads, lowering for high-speed aerodynamics) and adapt to different driving scenarios.
2. Pressure Stability Maintenance: Works with the vehicle’s air suspension ECU (Electronic Control Unit) to maintain consistent air pressure in the system. When air leaks slightly (e.g., from air spring seals), the compressor automatically activates to supplement pressure, preventing sudden changes in ride height and ensuring stable handling.
3. System Compatibility: As a valve-free unit, it is designed to pair with the Model S’s original valve assembly (separate component) — preserving the factory’s modular design logic, which allows targeted replacement of the compressor (without replacing the entire valve system) to reduce maintenance costs.

• Compressor Casing: Made of aluminum alloy (heat conductivity ≥150 W/(m·K)) with a corrosion-resistant coating, ensuring efficient heat dissipation during continuous operation (avoids overheating damage) and resistance to rust from underbody moisture or road salt.
• Internal Motor & Piston: The drive motor uses copper-wound coils (insulation class H, withstands 180°C) for stable power output; the piston is made of carbon fiber-reinforced PTFE (polytetrafluoroethylene), which reduces friction and wear—extending the compressor’s service life to match OEM standards (typically 80,000–100,000 km under normal use).
• Sealing Components: Uses nitrile rubber (NBR) seals with high pressure resistance (up to 15 bar) and oil resistance, preventing air leakage from the compressor’s internal air chambers and ensuring efficient pressure build-up.

1. Lift the vehicle’s front end and secure it with jack stands (ensure stable support); remove the front underbody splash guard to expose the air suspension compressor compartment (located near the front left wheel well).
2. Disconnect the electrical connector (12V power supply) and air hose from the old compressor—note the air hose’s orientation to avoid misconnection; then remove the 4 mounting bolts (10mm socket) that secure the compressor to the bracket.
3. Take out the old compressor and clean the mounting bracket with a dry cloth—wipe away dust, oil, or debris to ensure the new compressor sits securely.
4. Place the CFN compressor (6006403-00-ABZC) onto the bracket, align the mounting holes, and hand-tighten the 4 bolts (avoid cross-threading); then use a torque wrench to tighten them to 8±0.5 Nm (per Tesla’s official specs).
5. Reconnect the air hose (ensure a tight seal—no air leakage) and electrical connector; do not start the compressor yet.
6. Use a Tesla diagnostic tool (e.g., Tesla Toolbox) to perform two critical steps:
   • System Calibration: Initialize the compressor to match the Model S’s air suspension ECU, ensuring pressure detection and activation thresholds are correct.
   • Leak Test: Pressurize the system to 8 bar and check for leaks at the air hose connection and compressor seals (use soapy water to detect bubbles—no leakage allowed).
7. Reinstall the front underbody splash guard, lower the vehicle, and test the air suspension: activate ride height adjustment (e.g., “High” → “Standard” → “Low”) to confirm the compressor operates normally (no abnormal noise) and the suspension adjusts smoothly.

Note: Since this unit does not include the valve assembly, ensure the original valve assembly (or a new OEM-matching valve) is in good condition before installation—faulty valves may cause pressure loss, leading to frequent compressor activation and premature failure. For 2016 Model S produced after April, confirm the vehicle’s VIN to avoid mismatches (later 2016 units may use updated compressor part numbers like 1027911-00-H/G/F, which are not compatible with this unit).
