Walker 256-1033 Engine Oil Pressure Switch

Engine Oil Pressure Switch Overview

Walker 256-1033 is an OE replacement engine oil pressure switch built to monitor lubrication pressure and send a warning signal when pressure drops below safe limits. It is a direct-fit solution for a wide range of Audi and Volkswagen applications, including Audi A3, Audi A4, Audi A6, and Volkswagen GTI, Golf, Tiguan, and Atlas models.

Key Features

• OE replacement oil pressure switch for factory-style pressure monitoring.
• Matches OE specifications for pressure threshold, thread size, terminal type, and electrical response.
• High-temperature and oil-resistant construction for engine bay exposure.
• Female connector with one blade-pin male terminal for factory-style electrical connection.
• Direct-thread design for installation at the factory oil pressure switch location.

Detailed Description

Walker 256-1033 is engineered to restore accurate oil pressure signaling in vehicles that rely on an engine-mounted pressure switch to trigger the warning lamp or communicate with the ECU. The switch is built to the same functional requirements as the original part, helping maintain proper low-pressure alerts and reducing the risk of internal engine damage caused by loss of lubrication. This part number 256-1033 is listed for multiple Audi and Volkswagen platforms, including Audi TT Quattro, TTS Quattro, A3, A4, A5, A6, Q5, and Volkswagen Arteon, Atlas, GTI, Golf, Jetta, Passat, and Tiguan applications. Part number 256-1033 is a practical choice for drivability repairs, scheduled maintenance, or engine rebuild work where accurate oil pressure monitoring is required.

What It Helps Address

• Oil warning light flickering or staying on.
• False low-oil-pressure warnings.
• No signal when actual oil pressure drops.
• Faulty factory oil pressure switch operation.
• Loss of reliable lubrication-system warning feedback.

Installation Notes and Tips

Install in the factory oil pressure switch location and connect to the existing wiring harness. The switch is designed for direct OE-style fit, so no wiring changes are required when the vehicle application matches the listed fitment. Verify the pressure range and connector style against the original part before installation, especially on applications with notes such as 2.15-2.95 BAR or 2-pin configurations.

Quality Assurance

Walker Products manufactures this switch to OE specifications for fit, pressure response, and electrical function. The unit uses materials selected for heat and oil exposure to support consistent operation in demanding engine environments.
