Audi A8 D3 Intelligent Multi-pass Air Suspension Shock Valve Block

Upgrade of core functions
Six interfaces for precision control: Integration of special interfaces for pump, four-wheel shock absorber and gas tank, realizing independent closed-loop management of the gas circuit and eliminating chronic leakage caused by aging of the seal of the traditional valve body.
Millisecond dynamic leveling: In response to the body height sensor signal, single-wheel filling/exhausting is completed within 0.3 seconds, solving the problem of parking collapse and driving “adjustment timeout”.
Fault prediction and isolation: The built-in pressure sensor monitors the flow of the air circuit in real time, automatically isolates the leaking shock absorber air circuit, triggers the MMI instrumentation warning (e.g., “suspension failure”), and prevents the compressor from overheating and damaging.

Technical differentiation highlights
low-temperature adaptive algorithm: optimize the 30 ℃ cold start air circuit on and off logic, to cure the old winter frequently reported “high temperature shutdown” fault.
Compact anti-collision layout: the valve body is directly embedded in the rear axle bracket, avoiding the risk of chassis cuts and scrapes, and adapting to the D3's all-terrain passability needs.

Accurately solving D3's pain points
Collapse >10mm after 48 hours of resting - Sealing redundancy design completely blocks slow leakage
Loss of control of body roll in cornering - Millisecond single-wheel inflation to compensate for the support force
Fault code “Leakage detected”- Intelligent isolation of leakage points and precise localization.





Analysis of design differences:
1. Innovate for the defects of the old model: the old D3 Air suspension shock valve block frequently leaks due to weak sealing (accounting for 70% of failures), the new model solves the problem completely through double O-rings + metal inserts;
2. predictive fault management: different from passive maintenance, new leakage self-diagnosis and isolation function to reduce the risk of collateral damage to the compressor;
3. Low-temperature scenarios: the old winter air circuit response hysteresis, the new optimized low-temperature pass-through algorithm to ensure the stability of the cold environment.
