Two air suspension compressor faults - what is the correct use of lift system?

[willsonrobert]

I had the suspension compressor replaced on June 22 along with airline bundles which had split open. July 7 I got error TAS_a218 suspension adjustment unavailable which cause the front of the truck to be raised to extract while the back nearly bottomed out. Along with a whole host of other errors such as no self drive, no vehicle hold, no regenerative braking. My question is, how much are you allowed to raise and lower the cybertruck before it is considered damaging to the compressor system? The SC technician seems to believe I was overusing it, but what does that mean? Are you only supposed to lift the truck once a month?

Well they have an entry mode that deflates it everytime you go into park and when you go into drive it inflates back to medium height unless your in beast mode (low) or custom settings. Everytime you hit 70mph it will also lower to low mode automatically. Beings it self adjusts in all these cases, I don’t believe one can over use it. Even if you’re sitting in the driveway constantly cycling between high and low. The compressor is tiny as well as the tank it refills. Compressor will stop due to overheating and cool its self off before refilling the tank to max. You cannot go from entry to fully extract mode without it having to kick on, there simply isn’t enough volume in the tank.

Per Tesla Service AI (for what its worth):

Based on the available information, Tesla does not publish specific language defining "overuse" or misuse of the Cybertruck's air suspension system in terms of frequency of raising and lowering.

The owner's manual provides guidance on:

When to adjust ride height: For extra ground clearance (steep driveways, deep snow, speed bumps) or when you need extra space above the vehicle (parking garages).
Automatic adjustments: The system automatically returns to preferred ride height based on speed and distance thresholds (typically after 100 ft or at certain speeds).
Caution requirements: Ensuring the vehicle is clear of obstacles above and below before adjusting height.
Auto-raising locations: The system saves locations where you've raised the suspension and automatically adjusts when you return.

The manual focuses on proper use cases and safety precautions rather than defining usage limits. If you're concerned about potential warranty implications related to suspension use, you can check warranty details in Specs & Warranty > Warranty in the Tesla app, or contact Tesla Service at 877-798-3752 for specific guidance about your usage patterns.

Sounds like the air suspension valve block is bad, it also contains the pressure sensor.
Either that or the rear controller (less likely, the harness between the two).

Compressor has temperature sensor along with software duty cycle limits.

Air lines should never blow out.

My air suspension valve block failed on an Alaska road trip. Front high, rear low. I lost FSD for a thousand miles . The block was replaced in Anchorage at the Tesla Service Center. All my camping gear had to be removed from the vault to get access to the compression system. They let me put my gear in the vault of one their Cybertrucks awaiting registration while waiting for new block to be shipped from Seattle. Great service.
