Replace the air suspension compressor on a 2024 Model S Plaid. The compressor is mounted in the front of the vehicle and supplies pressurized air to all four corner struts via the manifold/valve block.

Warnings

Tools required

Parts

• Air Suspension Compressor Assembly (manufacturer-specified for 2024 Model S Plaid) × 1 — OEM Tesla air suspension compressor — verify by VIN
• Compressor isolation grommets/bushings (if not supplied with new unit) × 1 — OEM specification

Preparation

1. Park on level ground, place in P, engage parking brake.
2. Exit ALL doors with the key fob away from the vehicle. Wait at least 2 minutes for HV systems to fully de-energize, even on this non-HV job.
3. Disconnect the low-voltage battery. On 2024 Model S Plaid this is typically a 16V lithium unit located under the rear seat — verify exact location for your VIN before service. Some configurations retain a 12V in the frunk under the nose cowl.
4. DO NOT touch, cut, or pierce ANY orange cable — these are high-voltage and lethal.
5. If at any point you encounter an orange cable, an HV component, or are unsure if a system is de-energized: STOP and consult a Tesla-certified technician.
6. Place the vehicle in Jack Mode / Transport Mode via the touchscreen BEFORE disconnecting the low-voltage battery — this disables auto-leveling and allows lifting without the suspension fighting the lift.
7. Depressurize the air suspension reservoir per manufacturer-specified procedure prior to disconnecting any pneumatic line.
8. Identify the compressor location on this vehicle (typically in the front underbody area near the front sub-frame) and confirm access from below.

Procedure

1. 1

   Place vehicle in Jack Mode and lift
   With the vehicle still powered, enter the touchscreen Service menu and enable Jack Mode (Transport Mode) to disable auto-leveling. Then power down, exit, and wait 2 minutes. Lift the vehicle using Tesla-approved lift pad locations only. Never lift on the battery pack or pinch welds without approved adapters.
   ⚠Lifting at non-approved points on a Plaid will damage the HV battery enclosure.
2. 2

   Disconnect low-voltage battery
   Locate the low-voltage battery (16V Li-ion under rear seat on most 2024 Plaid; verify by VIN). Remove the negative terminal first using a 10mm wrench, then isolate the cable so it cannot contact the post. Wait several minutes for capacitors to bleed down before continuing.
3. 3

   Remove underbody aero/access panel
   Remove the front underbody aero shield to access the compressor area. Fasteners are typically T25/T27 Torx and plastic push pins. Keep all fasteners organized — the aero panel is critical for thermal and aerodynamic performance and must be reinstalled fully.
   ℹ️Damaged or missing aero panel fasteners must be replaced — loose panels at highway speed can detach.
4. 4

   Locate compressor and depressurize system
   Locate the air suspension compressor assembly. Confirm the system is depressurized — there should be no audible hiss when the discharge line is loosened. If pressure remains, STOP and complete the depressurization procedure before continuing.
   ⚠️A pressurized line can whip violently and injure eyes or skin if disconnected under pressure.
5. 5

   Disconnect electrical connector
   Release the locking tab on the compressor's electrical connector and disconnect it. Inspect the connector and pins for corrosion or moisture intrusion — this is a common failure mode and may indicate why the original compressor failed. Replace the connector pigtail per OEM specification if corroded.
6. 6

   Disconnect pneumatic line(s)
   Disconnect the air supply line from the compressor outlet. Most Tesla air suspension lines use push-to-connect fittings: depress the collar and pull the line straight out. Cap or cover the open line and the open port immediately to prevent debris ingress, which can clog valve block solenoids.
   ⚠Any debris entering the pneumatic system can damage the valve block — keep all openings capped.
7. 7

   Remove compressor mounting bolts
   Support the compressor by hand. Remove the mounting bolts/nuts securing the compressor bracket to the chassis. Note the orientation of any rubber isolation grommets — these dampen compressor vibration and must be transferred to the new unit (or replaced) in the same orientation.

   Mounting Bolts27 Nm (20 lb-ft)
8. 8

   Remove old compressor
   Lower the compressor out of the vehicle. Inspect the mounting bracket and isolators for cracks or wear. Note the position of any heat shields or wire routing clips for reassembly.
9. 9

   Transfer brackets and prepare new compressor
   If the new compressor is supplied without a bracket, transfer the bracket and isolators from the old unit. Verify the new compressor matches the old by part number and connector style before installation. A mismatched compressor may not be recognized by the air suspension ECU.
10. 10

    Install new compressor
    Position the new compressor and start all mounting bolts by hand. Ensure the isolators are seated correctly. Torque the mounting bolts to specification.

11. 11

    Reconnect pneumatic line and electrical connector
    Push the air line firmly into the compressor outlet until it fully seats and locks. Tug-test to confirm engagement. Reconnect the electrical connector until the lock tab clicks. Route any wiring or air lines back into their original clips to prevent chafing.
    ⚠An incompletely seated air line will leak and cause the compressor to run continuously, leading to premature failure of the new unit.

Reassembly

1. Reinstall the front underbody aero panel with all original fasteners. Replace any broken push pins.
2. Lower the vehicle to the ground at all four wheels.
3. Reconnect the low-voltage battery (negative terminal last). Torque to OEM specification — refer to Tesla Service Manual.
4. Power up the vehicle and exit Jack Mode via the touchscreen Service menu.
5. Allow the air suspension system to repressurize and self-level. The compressor will run for an extended period on first startup — this is normal as the reservoir refills from empty.
6. If equipped/available, run the air suspension calibration procedure via Tesla service software. Without this, ride height accuracy may be off.

Verification

• Confirm no air suspension fault messages on the touchscreen after a full power cycle.
• With the vehicle running and at rest, listen for compressor cycling — it should run to fill the reservoir, then stop. Continuous running after 10+ minutes indicates a leak in the system.
• Spray soapy water on the compressor outlet fitting and electrical connector area; check for bubbles indicating an air leak.
• Cycle the suspension through Low / Standard / High ride heights via the touchscreen and verify all four corners respond and reach commanded height.
• Measure ride height at all four corners and compare to Tesla published spec for Plaid trim — if outside spec, the system requires calibration via Tesla service software.
• Test drive and confirm the suspension self-levels within a few seconds at speed transitions and that no faults reappear.
