Engine Oil Pump Assembly 03L115105B / 3L115105B for VW Golf, Jetta, Passat, Transporter & Audi A3 A4 Q5 1.6 2.0 TDI

Precision OEM Mechanical Rotor Oil Pump for Consistent Pressure Control, Efficient Oil Circulation, and Wear Protection in VAG 1.6L & 2.0L TDI Diesel Engines

Overview:

Maintain optimum engine longevity and lubricative performance in your Volkswagen, Audi, SEAT, or Skoda vehicle with our OEM Replacement Engine Oil Pump Assembly (Part Number 03L 115 105 B / 3L 115 105 B, interchange with 03L 115 105 C). Operating as the critical heart of the engine's lubrication system, this mechanical rotor pump continuously feeds motor oil under pressurized flow to critical internal components—including crankshaft main bearings, connecting rods, turbochargers, and valvetrain assemblies—preventing low oil pressure warnings, excessive friction, and premature wear.

Manufactured to stringent original equipment specifications, this direct drop-in replacement pump features a heavy-duty die-cast aluminum housing and a precision-machined 33-tooth gear drive, ensuring seamless installation, leak-free sealing, and long-term operating reliability for routine maintenance or complete engine overhauls.

Key Features:

  • Direct OEM Fitment: Exact replacement for part numbers 03L115105B, 3L115105B, and 03L115105C without custom modifications required.

  • Stable Oil Line Pressure: Delivers uniform volume flow across all RPM ranges to protect critical bearings and turbocharger oil feed lines against oil starvation.
