Vacuum Pump 07K145100H 904-817 For VW Jetta Passat Beetle Golf Rabbit Audi 2.5L

Vacuum Pump for VW and Audi

This mechanical vacuum pump supplies the necessary vacuum assist to the brake booster and emission control valves, referencing OEM numbers 07K145100H and 904-817 for VW and Audi 2.5L engines.

Overview

This replacement vacuum pump generates the continuous pneumatic vacuum pressure required for power brake assistance and vacuum-actuated engine subsystems. Automotive technicians can install this vacuum pump to resolve hard brake pedals, vacuum leaks, and associated diagnostic trouble codes. It serves as a direct mechanical replacement for worn or leaking factory pumps on 2.5-liter engines.

Built For Performance

• Direct replacement engineered to match factory mounting locations and vacuum hose connections.
• Precision-machined internal rotor ensures reliable vacuum generation across the entire engine RPM range.
• High-grade sealing rings prevent engine oil from leaking out of the pump housing.
• Durable metal casting resists thermal warping and high engine bay temperatures.

Fits These Machines

• for VW Jetta 2.5L
• for VW Passat 2.5L
• for VW Beetle 2.5L
• for VW Golf 2.5L
• for VW Rabbit 2.5L
• for Audi 2.5L

On-The-Job Use

• Restoring proper vacuum assist to the power brake booster to ensure safe stopping distances.
• Resolving engine oil leaks dripping from the back of the cylinder head near the vacuum assembly.
• Supplying steady vacuum pressure to emission control valves and HVAC mode doors.

Specs At A Glance

Good To Know

Q: Why do these vacuum pumps commonly leak oil? A: The internal seals degrade over time due to high engine temperatures, allowing pressurized engine oil from the camshaft housing to seep past the pump face. Replacing the entire pump or its seals restores a dry engine bay.

Q: What are the signs of a failing vacuum pump? A: A hard brake pedal that requires extra effort to depress is the most common symptom, often accompanied by oil leaks or hiss noises from the engine bay.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
