Heavy Duty Truck Cabin Cab Tilt Position Sensor Pressure Switch Replacement for MAN TGA TGS TGX F2000 VW | OEM 81255200177 81255200161 2V5941555A

Product Overview The 81255200177 / 81255200161 / 2V5941555A Cabin Cab Tilt Position Sensor / Hydraulic Pressure Switch is an essential fleet safety component engineered as a premium aftermarket replacement for MAN heavy duty commercial vehicles and Volkswagen (VW) truck series. Installed inside the driver’s cabin hydraulic tilting line network or lower lock hook assembly, this dual-function switch registers the physical orientation or internal hydraulic sealing pressure profiles of the cab. By feeding immediate status data to the central body management microprocessor (ZBR/CBCU), it rules out hazardous fleet configurations by ensuring the cab is perfectly dropped and locked before permitting engine ignition loops or highway transit operations. Technical Specifications Primary MAN Factory OE Reference Codes: 81255200177, 81.25520-00177, 81255200161, 81.25520-00161 Volkswagen (VW) Cross-Reference Code: 2V5941555A, 2V5 941 555 A Component Type: Heavy-Duty Truck Cabin Tilt Indication Switch / Hydraulic Line Pressure Sensor Terminal Array: Factory-spec alignment pins for a fully weatherproof harness lock Housing Properties: Rugged, anti-corrosive brass body interface married to a high-strength polymer shroud Condition: Brand New Premium Aftermarket Replacement Vehicle & Fleet Chassis Compatibility Matrix This replacement cab tilt indicator module precisely matches factory electrical thresholds and mounting threading parameters, providing direct drop-in setup across prominent European commercial transit lines: Truck Family & Platform Series Chassis Specifications & Application Profiles MAN TG-X & TG-S Series Fits modern premium long-haul tractor platforms (e.g., TGX 18.440, 26.480) and heavy vocational construction rigs (e.g., TGS 33.400, 41.440 dump trucks) fitted with hydraulic lift grids. MAN TG-A Series Widespread integration across heavy multi-axle logistics tractors, intercity rigid cargo chassis, and concrete mixers utilizing active cabin status monitoring. MAN TG-L & TG-M Fleet Lines Direct fitment for medium-duty regional distribution box trucks and specialized urban municipal service platforms. MAN F2000 / Evolution Series Compatible with classic heavy haulage platforms operating original hydraulic tilt signaling frameworks. Volkswagen (VW) Commercial Series Fits selective heavy-duty vocational trucks and platform-shared bus chassis utilizing matching part number 2V5941555A parameters. Performance Benefits Eliminates False Dashboard Alarms: Instantly cures typical vehicle electronics glitches such as a persistent, flickering “Cab Unlocked” cluster warning light despite the cab being manual-locked down tight. Vibration-Proof Structural Core: Internal mechanical contact points are heavily reinforced to withstand continuous chassis shuddering, frame articulation, and intense job-site road vibrations without sending broken signals. IP67 Moisture-Isolated Enclosure: Designed with premium-grade fluid-tight seals to isolate internal circuit layers against flying road slush, high-pressure under-cab chassis washes, and freezing winter operations. Maintenance Tip: In heavy construction environments or long-distance line hauls, a failing 81255200177 switch often causes a critical safety lockdown where the truck’s central module triggers an audible warning buzz or halts starting protocols because it registers the cabin as “open”. Because this sensor sits underneath the cabin near hydraulic linkages, it is routinely sprayed by road salt, hydraulic oil residues, and wet mud. When replacing this unit, ensure the cabin is fully tilted and safely secured with mechanical safety props. Thoroughly clean old hydraulic dirt away from the mounting thread area to preserve the seal, avoid over-torquing the brass hex housing, and push the wire loom plug in until the lock tab clicks down to preserve a completely clean electronic interface.
