Overview:

Maintain maximum operational reliability for your longitudinal 1.8T engine with our Premium Engine Oil Pump Assembly, direct factory replacement for Part Numbers 058 115 105 A, 058 115 105 B, and 058 115 105 C. Functioning as the core of your engine's lubrication system, this pump continuously forces motor oil under steady pressure to critical internal moving parts—including crankshaft bearings, camshafts, valvetrain assemblies, and turbocharger bearings—preventing friction, overheating, and severe mechanical wear caused by oil sludge accumulation.

Manufactured to meet or exceed strict original equipment performance standards, this replacement pump offers exact drop-in fitment, reliable pressure regulation, and long-lasting durability for routine maintenance, oil pressure troubleshooting, or complete engine rebuilds.

Key Features:

• Direct OE Replacement: Precision-built bolt-on replacement for the entire 058115105 family (A, B, C revisions) without modification.

• Consistent Pressure Regulation: Delivers stable oil volume and line pressure across all operating speeds to guard against low oil pressure warnings and thermal stress.

• Heavy-Duty Construction: Built with high-strength die-cast aluminum alloy housing and precision internal gears for maximum wear resistance and extended service life.

• Factory Quality Tested: 100% flow and pressure-tested to ensure leak-free seal tolerances and original performance out of the box.
