Heavy Duty Truck Air Bellow Suspension Pressure Sensor Replacement for DAF Mercedes-Benz MAN Iveco | WABCO OEM 4410400080 4410400180

Product Overview The 4410400080 / 4410400180 Air Bellow and Suspension Fluid Pressure Sensor is an industrial-grade pneumatic safety and calibration component engineered as a premium aftermarket replacement for DAF, MAN, Mercedes-Benz, Iveco commercial trucks, passenger transit coaches, and heavy duty trailers running Electronically Controlled Air Suspension (ECAS) architectures. Manufactured to match original equipment design tolerances, this high-precision sensor mounts directly onto the under-chassis air spring bellows or central leveling valve blocks. By providing instant microsecond-level linear voltage feedback of internal air bellow pressure to the vehicle’s electronic chassis computer, it enables automated fleet ride-height optimization, perfect side-to-side alignment, and precise multi-axle weight balancing under variable logistics cargo payloads. Technical Specifications Primary WABCO Cross-Reference Codes: 4410400080, 441 040 008 0, 4410400180, 441 040 018 0 DAF Fleet OE Reference Codes: 1324749, 1505287 MAN Truck OE Reference Codes: 81274210134, 81.27421-0134, 81274210161 Mercedes-Benz OE Reference Codes: A0045421518, 0045421518, A0055422418, 0055422418 Iveco / Renault OE Reference Codes: 503135431, 5010423011 Component Class: Inductive/Piezoresistive Fluid Air Suspension Bellow Pressure Switch Sender Housing Properties: Heavy-duty, anti-corrosive brass threaded base block fused with a high-strength polymer 3-pin wiring shroud Condition: Brand New Premium Aftermarket Replacement Vehicle & System Compatibility Matrix This replacement air shock logging sensor precisely replicates original factory electrical resistance indexes and mechanical seating profiles, ensuring direct drop-in setup across prominent European commercial truck configurations and shared multi-axle trailer networks: Truck Manufacturer & Chassis Family Suspension Lineup & System Application Profiles DAF Trucks Series (XF 95, XF 105, CF 75, CF 85 Fleet Systems) Integrates seamlessly with main chassis rear-axle leveling systems and tag-axle air spring management systems running under OE 1324749. MAN Trucks Series (TGA, TGS, TGX, F2000 Fleet Ranges) Fits premium heavy-duty long-haul transport tractors, rigid distribution setups, and vocational tippers running intelligent WABCO ECAS loops (OE 81274210134). Mercedes-Benz Trucks (Actros MP1/MP2/MP3, Axor, Atego Platforms) Direct cross-reference fitment for international commercial logistics chassis utilizing factory A0045421518 air bellow pressure monitoring lines. Iveco & Scania & Trailer Chassis (Eurostar, Stralis, SAF / BPW Axle Lines) Compatible with commercial passenger transport coaches and modern logistics trailer fleets operating smart under-frame air suspension leveling valve blocks. Performance Benefits Restores Chassis Leveling Balance: Directly corrects typical pneumatic system failures such as leaning truck tilt, sudden suspension collapsing under load, sluggish air bag inflate/deflate responses, or persistent “ECAS Leveling Warning” alerts on the driver dashboard. Pneumatic Shock Endurance: Engineered with an upgraded internal sensing chip calibrated to handle intense fluid pressure surges caused by sudden pothole impacts, bumpy vocational job sites, and high trailer load dumps. IP67 Corrosion-Proof Shroud: Built with high-strength anti-oxidation metal threads and hermetically sealed polymer headers to lock out under-chassis water spray, road grease, mud, and corrosive winter road salt. Maintenance Tip: In long-haul logistics environments, a failing 4410400080 / 4410400180 air bellow pressure sensor usually triggers an uneven ride or causes the pneumatic valves to hunt (continuously venting and pumping) without settling down. Positioned directly underneath the frame rails near the axles, this sensor is constantly subjected to water blasting and road debris. Before unscrewing the old unit, ensure the truck’s air reservoirs are fully bled to atmospheric pressure and the chassis is safely secured on mechanical jack stands. Clean out any corrosion in the mounting block thread cavity, verify that the integrated rubber seal sits perfectly flush, and press the harness terminal plug tightly home until it clicks to ensure a completely moisture-isolated electrical connection.
