Product Description
This compressor serves as the core air supply component for the AIRMATIC air suspension system in Mercedes-Benz R-Class W251 chassis vehicles. 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, fatigue, moisture ingress, or burnout.
As the "heart" of the Mercedes-Benz air suspension system, the compressor supplies compressed air to maintain vehicle ride height and automatic self-leveling functionality. When compressor failure occurs, the system cannot raise the vehicle to preset height, and the instrument panel displays an "Air Suspension Stop Automatic Leveling" fault.
Manufactured to original equipment specifications using high-quality materials, this product delivers stable and reliable air supply performance. Compatible with Mercedes-Benz R-Class W251/V251 chassis (2006-2013), including R320 CDI, R350, R500, R63 AMG and other models equipped with AIRMATIC air suspension.
Frequently Asked Questions
Q1: How can I tell whether the air suspension compressor is already damaged?
Common signs include: noticeably louder noise or abnormal sounds, slow vehicle rising speed (over 2 minutes to reach normal height), frequent compressor operation (starting every 1-2 minutes), and "Air Suspension Stop Automatic Leveling" warnings on the instrument panel.
Q2: What are the common causes of compressor failure?
Common causes include overheating from prolonged operation, saturated dryer allowing moisture ingress, worn compressor piston rings, burned relay contacts, and blocked compressor air intake.
Q3: Which vehicles does OE 2113200304 fit?
This compressor is suitable for Mercedes-Benz W220 S-Class (2000-2006), W211 E-Class (2003-2009), and W219 CLS-Class (2005-2011).
Q4: After replacing the compressor, the instrument panel still displays an "Air Suspension Fault" warning. What is the cause?
Possible causes include: uncleared fault codes, faulty compressor relay, internal leakage in distribution valve, air spring or line leaks, or faulty height sensor.
Q5: What accessories are recommended to replace at the same time as the compressor?
Recommended simultaneous replacements: relay K67/KG54 TU 080, air line connector O-ring seals, and air intake filter. Also inspect distribution valve condition and check for air spring leaks.
Q6: The compressor runs but the vehicle body does not rise. What is the cause?
Possible causes include faulty distribution valve, severe air spring leaks, insufficient compressor pressure, or blocked/detached air lines.
Q7: Is loud noise from the compressor during operation normal?
No, normal operation produces relatively low and steady sounds. Abnormal noise indicates worn components, blocked air intake, or loose mounting bolts.
Q8: The compressor runs continuously without stopping. What is the cause?
Typically indicates the system cannot reach preset pressure due to air spring leaks, internal distribution valve leakage, air line leaks, or faulty height sensor.
Q9: How often should the compressor be replaced?
No fixed interval - service life depends on usage frequency and environment. Typical design life is 8-10 years or 150,000-200,000 km. Replace when low air supply or abnormal noise is observed.
Q10: What is the function of the dryer on the compressor?
The dryer absorbs moisture from compressed air using desiccant, preventing corrosion in the distribution valve and air spring aging. Integrated dryers don't need separate replacement.
Q11: What setup is required after installing a new compressor?
Required steps: clear fault codes, perform compressor activation test, and perform level calibration and ride height initialization using diagnostic tools like XENTRY.
Q12: Does the dryer need to be replaced after replacing the compressor?
If the new compressor has an integrated dryer (like OE 2113200304), no separate replacement is needed.
Q13: Can the W220 and W211 compressors be interchanged?
Yes, OE 2113200304 is compatible with both W220 S-Class and W211 E-Class as their air suspension compressor specifications are identical.
