Felendo air suspension compressor for  Mercedes-Benz E-Class or CLS-Class W212 2123200404
Precision Engineering. Restored Ride Quality.
Is your Mercedes-Benz E-Class or CLS-Class sitting unevenly, sagging at one corner, or &#8211;displaying an AIRMATIC warning light? The culprit is often a failed air suspension compressor. The FELENDO 2123200404 Air Suspension Compressor is a premium, direct OEM-grade replacement engineered to restore your vehicle&#8217;s legendary comfort and handling.
As a trusted name in automotive air suspension systems, FELENDO delivers components that meet or exceed original equipment specifications. This compressor is manufactured to the same rigorous standards as the original WABCO unit that came factory-installed on your Mercedes-Benz. It connects directly into your vehicle&#8217;s existing air lines and electrical connectors for a fast, plug-and-play installation.
The compressor is the heart of your Mercedes-Benz AIRMATIC suspension system. It draws in ambient air, compresses it, and delivers pressurized air to the air springs or struts to maintain proper ride height, adjust suspension stiffness, and ensure the perfect balance of comfort and handling that Mercedes-Benz is known for. The system works in coordination with sensors and valves to regulate pressure in real time, adapting to road conditions and driving dynamics.
Choose FELENDO for reliability, performance, and peace of mind – the smart, cost-effective solution to keep your Mercedes-Benz performing at its best.

Symptoms of a Failing Compressor
<ul>
<li>
Vehicle sagging – one or more corners of the vehicle sit lower due to insufficient air pressure.
</li>
<li>
Noisy or overworking compressor – runs constantly, makes loud humming or grinding noises, or fails to shut off.
</li>
<li>
Complete suspension failure – compressor does not activate, leading to loss of ride height adjustment and rough ride quality.
</li>
<li>
AIRMATIC warning light – the dashboard &#8211;displays a suspension system warning.
</li>
</ul>
Installation Tips
<ul>
<li>
Before replacing the compressor, inspect all air suspension lines and fittings for cracks, kinks, holes, or other damage.
</li>
<li>
Inspect the air springs (airbags) for leaks – a leaking airbag can cause the new compressor to fail prematurely.
</li>
<li>
Always replace the compressor relay before installing the new compressor, even if the old relay appears to function – this is a manufacturer specification.
</li>
<li>
Ensure the system is absolutely leak-proof after repair – any leak compromises the functioning of the suspension compressor.
</li>
</ul>
<blockquote>
Important: Before replacing the compressor, verify there are no leaks in air lines or in the air springs themselves. If the compressor fails to turn on or cannot reach the correct pressure (with no leaks), the compressor is the likely issue.
</blockquote>
