A4VG140 Hydraulic Pump
Check charge circuit: Verify charge pump pressure (should be 280 bar continuous). If low, clean/replace the charge filter or repair the charge pump.
Inspect control system: Check the electro-hydraulic proportional valve (E-type control) for power supply or wiring issues. Use a multimeter to confirm 24V DC input.
Check for leaks: Inspect main circuit hoses and fittings—leaks reduce pressure. Tighten fittings or replace worn hoses.
