Product Description
This compressor serves as the core air supply component for the AIRMATIC air suspension system in Mercedes-Benz W639 chassis vehicles (Vito/Viano). Designed as a single pump assembly with integrated dryer and thermal protection, it's ideal for repair scenarios where original compressors have failed due to aging, moisture ingress, or burnout.
As the "heart" of the air suspension system, the compressor supplies compressed air to maintain vehicle ride height and automatic self-leveling functionality. When compressor pressure becomes insufficient, the system cannot raise the vehicle to preset height, triggering "Air Suspension Stop Automatic Leveling" warnings.
The Arnott brand offers a corresponding product (P-2800) with installation manual. This unit features epoxy coating treatment to prevent corrosion and extend service life.
Key Features
- Single Pump Assembly: Includes compressor body, integrated dryer, and thermal protection
- Wide Compatibility: OE 6393200204 fits multiple Mercedes-Benz Vito/Viano W639 models
- Reliable Air Supply: Meets air suspension demands under daily and heavy load conditions
- Corrosion Protection: Epoxy coating prevents corrosion and extends service life

Frequently Asked Questions
Q1: How can I tell whether the Mercedes-Benz W639 compressor is already damaged?
Common signs include: noticeably louder noise or clicking sounds, slow vehicle rising (over 2 minutes), frequent compressor operation (every 1-2 minutes), AIRMATIC malfunction warnings, and rear axle sinking. For diagnosis: start vehicle and let compressor run for 2 minutes - if body doesn't rise or compressor runs continuously, it has likely failed.
Q2: What are the common causes of compressor failure on the W639?
Common causes: 1) Frequent heavy loads causing overheating; 2) Saturated dryer allowing moisture corrosion; 3) Worn piston rings reducing efficiency; 4) Burned relay contacts; 5) Blocked air intake affecting heat dissipation.
Q3: Which vehicles does OE 6393200204 fit?
Suitable for Mercedes-Benz Vito/Viano W639 chassis (2003-2014) with AIRMATIC air suspension, including panel van and passenger versions. Also compatible with some Sprinter (W906) models - verify original OE part number for confirmation.
Q4: Is the Vito compressor interchangeable with the Viano compressor?
Yes, they are interchangeable. Both share the W639 chassis platform with identical air suspension compressor specifications.
Q5: After replacing the compressor, the instrument panel still displays an "Air Suspension Fault" warning. What is the cause?
Possible causes: 1) Uncleared fault codes; 2) Faulty compressor relay; 3) Internal distribution valve leak; 4) Air spring or line leaks; 5) Faulty height sensor. Check distribution valve first, then clear codes with diagnostic tool.
Q6: What accessories are recommended to replace at the same time as the W639 compressor?
Recommended simultaneous replacements: relay (prone to overheating), air line connector O-ring seals, and air intake filter. As a commercial vehicle with extended compressor operation, relay replacement is highly recommended.
Q7: The W639 compressor runs but the vehicle body does not rise. What is the cause?
Possible causes: 1) Faulty distribution valve; 2) Severe air spring leaks; 3) Insufficient compressor pressure; 4) Blocked or detached air lines. Check rear air spring condition first, then measure compressor output pressure.
Q8: Is loud noise from the W639 compressor during operation normal?
No, normal operation produces relatively low, steady sound. Abnormal noise indicates: 1) Worn piston rings; 2) Worn pump bearings; 3) Blocked air intake; 4) Loose mounting bolts. Replacement recommended for noticeably abnormal noise.
Q9: The W639 compressor runs continuously without stopping. What is the cause?
Continuous operation indicates system cannot reach preset pressure. Common causes: 1) Air spring leaks; 2) Internal distribution valve leakage; 3) Air line leaks; 4) Faulty height sensors. Check for air spring leaks first.
Q10: How often should the W639 compressor be replaced?
No fixed replacement interval. Design life typically 8-10 years or 120,000-150,000 km. As a commercial vehicle with frequent heavy loads, service life may be shorter. Replace when low air supply or abnormal noise is observed.
Q11: What is the function of the dryer on the W639 compressor?
The dryer contains desiccant to absorb moisture from compressed air, preventing distribution valve corrosion and air spring aging. Integrated dryer doesn't need separate replacement, but when saturated (typically 5-7 years), compressor assembly must be replaced.
Q12: What setup is required after installing a new compressor?
Required steps with diagnostic tool: 1) Clear air suspension fault codes; 2) Perform compressor activation test; 3) Perform level calibration and ride height initialization. Road test recommended after calibration for adaptive learning.
Q13: What are the differences between the Vito and Viano W639 chassis?
Vito: utility commercial vehicle with basic specifications, some variants have leaf spring suspension. Viano: luxury business MPV with refined interiors and standard/high-spec air suspension. Both share identical air suspension compressor with same OE part numbers.
Q14: Is the W639 compressor interchangeable with the W906 (Sprinter) compressor?
Partially interchangeable - verify OE part number. W639 and W906 share some air suspension components with similar compressor structure and interface, but differences may exist between model years and configurations.
Q15: How can I confirm whether my W639 is equipped with AIRMATIC air suspension?
Check methods: 1) Center console ride height adjustment button; 2) Rubber air bag on shock absorbers; 3) Compressor running after startup; 4) Verify configuration via VIN code. High-spec Viano models typically standard, Vito requires configuration confirmation.
