Product Description
6393280030 Mercedes-Benz W639 04-14 Air Suspension Distributor Valve
Product Overview
The 6393280030 air suspension distributor valve is a core control component specifically designed for 2004-2014 Mercedes-Benz W639 chassis vehicles (Viano / Vito / V-Class). This valve plays a critical role in the air suspension system by precisely distributing compressed air from the compressor to the four air springs, serving as the central hub for ride height adjustment and vehicle attitude control.
The valve integrates multiple solenoid valves, controlled by the suspension control module based on signals from ride height sensors, delivering or releasing compressed air to each wheel's air spring as required, thereby achieving automatic ride height adjustment and stabilization.

Replacement OE Numbers
This product is a direct replacement for the following OEM part numbers:
6393280030, A6393280030, 639 328 00 30, A 639 328 00 30
Product Features
- Central Hub, Precise Distribution: The distributor valve serves as the "command center" of the air suspension system, directing compressed air to each air spring according to control signals, ensuring precise ride height adjustment.
- Integrated Pressure Sensor: The air suspension system's pressure sensor is integrated inside the distributor valve, not in the compressor. This sensor monitors system pressure and provides signals to the control module.
- Direct Replacement, OEM Quality: Manufactured to original OEM specifications, with identical interface and dimensions to the factory unit, requiring no additional modifications during installation.
- Color-Coded Ports for Quick Installation: Each air port is color-coded for easy identification and correct connection, effectively preventing installation errors.
- Long-Lasting Durability: Tested in electrical and pneumatic performance laboratories, featuring high-quality O-ring seals and electrical components for effective prevention of air leaks and electrical faults.

Frequently Asked Questions
Q1: How do I know if my W639 needs a new air suspension distributor valve?
Common symptoms include: vehicle sagging on one side or diagonally after parking; inability to adjust ride height while driving or slow response; suspension system fault warnings on the dashboard; hissing air leak sounds near the distributor valve; and the compressor running unusually frequently or overheating. Since the pressure sensor is integrated inside the distributor valve, a faulty valve may also prevent the compressor from starting. Note that vehicle sagging can also be caused by air spring leaks — it is recommended to perform air port swap testing to differentiate.
Q2: What should I pay attention to when replacing the distributor valve?
The following four points are critical: First, be sure to disconnect the vehicle's battery before replacement; Second, replace all O-ring seals at the same time to prevent secondary leaks from aged seals; Third, perform a pressure test on the air suspension system after installation to ensure a completely sealed system with no leaks; Fourth, if the distributor valve is being replaced due to a compressor burnout, the compressor relay must also be replaced simultaneously to prevent premature damage to the new components.
Q3: Does the distributor valve require programming or coding after replacement?
This is a physical replacement component and does not require complex reprogramming of the suspension control module. However, it is recommended to use a professional diagnostic tool to read and clear any fault codes after replacement. On the first startup after installation, observe whether the vehicle inflates and rises properly, and check for any abnormal air leaks or warning alerts.
