303.04.0086.03 Repair Kit for ECAS Solenoid Valves

What does an ECAS repair kit do?

This repair kit is a specialized service set designed to renew the internal components of solenoid valve blocks within an electronically controlled air suspension (ECAS) system. By replacing worn internal elements, this kit helps maintain the precise pneumatic control required to manage chassis height and stability under heavy loads.

Compatible vehicle makes and systems

These kits are primarily used in Mercedes-Benz and DAF trucks to restore the functionality of the valve block. The components are compatible with WABCO systems, allowing technicians to overhaul the air suspension assembly without the need for a complete, costly replacement of the entire valve block unit.

Maintenance and installation guidance

For workshop technicians, using a high-quality repair set helps prevent common issues such as air leaks, delayed level response, or sagging while parked. When performing maintenance, ensure all internal seals and plungers are correctly seated to maintain system pressure and precise electronic response.

Troubleshooting suspension stability

Regular inspection of the suspension system can prevent significant downtime. Choosing a professional service kit ensures that the electronic control commands are accurately translated into pneumatic action for stable vehicle height control.
