W000035441 X01-29150022 X03-20040011 Air suspension block valve for Lixiang L7 L8
1. Product Introduction
Original OE Number: W000035441, X01-29150022, X03-20040011
Product Name: Li-Auto Air Suspension Distribution Valve, Air Suspension Solenoid Valve Block Assembly, Air Suspension Height Control Valve, EAS Air Suspension Pressure Control Unit
Installation Position: Chassis air suspension compressor pipeline assembly, core main control valve of vehicle height system. Universal for the whole vehicle with no front-rear or left-right distinction. It controls independent inflation, high-pressure stabilization, static pressure holding, dynamic pressure relief and intelligent ride height adjustment for four-wheel air springs, serving as the core vulnerable component for Li-Auto L7 and L8 air suspension system.
Product Description
W000035441, X01-29150022 and X03-20040011 are original iterative interchangeable OE numbers for Li-Auto dedicated air suspension distribution valves, with identical structure, parameters and dimensions. As the core pressure control hub of Li-Auto EAS intelligent air suspension system, it accurately manages air intake, pressure stabilization, pressure locking and pressure relief logic of four air springs, balances vehicle body height in real time, filters road vibration, and improves riding comfort and high-speed driving stability, solving common faults of Li-Auto L7 and L8 such as body sagging, tilting and slow height adjustment.
The original valve block is a typical failure-prone part for Li-Auto new energy models. Working under harsh chassis conditions including dampness, high temperature around the battery pack, frequent start-stop and severe seasonal temperature changes, the original sealing rings are prone to aging, hardening and cracking, causing valve core sticking, slow solenoid response, micro air leakage and poor pressure holding. Typical vehicle faults include body sag after long-time parking, unilateral tilt, uneven four-wheel height, frequent compressor operation, slow or stuck height adjustment, air suspension warning light and leakage fault codes. Long-term faulty use will burn out the air compressor, damage the dryer and cause full air suspension system breakdown with high maintenance costs.
This interchangeable valve block is 1:1 reproduced strictly according to original OE data. The valve runner, solenoid frequency, pressure resistance, ECU signal, plug pins and pipeline interfaces fully comply with original standards. Adopting high-strength precision aluminum alloy body, high and low temperature resistant high-pressure fluororubber seals and anti-sticking rust-proof valve core with upgraded anti-carbon and anti-aging structure, it completely eliminates original defects of air leakage and valve sticking. Featuring accurate shunting, stable pressure holding and zero leakage under long-term high pressure, it supports non-destructive direct replacement without wiring modification or programming, perfectly matching the original Li-Auto EAS system. It thoroughly repairs various air suspension faults of L7 and L8 with ultra-low rework rate, ideal for auto repair shops, wholesale and cross-border export.

5. FAQ
Q1: Are the three OE numbers fully interchangeable?
A: Fully interchangeable. They are different batch iterative numbers for the same original valve. Hardware structure, ECU program, installation size and pressure resistance parameters are completely consistent for mutual replacement.
Q2: Does this valve have front/rear or left/right installation distinction?
A: No position difference, universal for the whole vehicle. One single SKU covers all compatible models, easy for stock management.
Q3: Can it be installed on mechanical suspension low-trim Li-Auto models?
A: Not applicable. It only fits L7/L8 high-trim models with factory air suspension. Mechanical chassis has no matching air suspension pipelines and control modules.
Q4: Can this valve be used for modified non-OEM air suspension systems?
A: Not recommended. This valve is dedicated to original Li-Auto EAS electronic control logic. Mismatched parameters will cause system errors, poor pressure holding and abnormal height adjustment.
Q5: Is programming required after replacement?
A: No programming needed. After in-situ replacement, evacuate pipeline air, complete air tightness test, clear fault codes and calibrate body height, the vehicle ECU will automatically identify and adapt.
Q6: What faults require valve block replacement?
A: Body sag after parking, unilateral tilt, uneven four-wheel height, frequent compressor operation, slow and stuck lifting, air suspension warning light and system leakage/pressure holding failure fault codes. A new valve block can completely fix the above faults.
