Walker 256-1077 Engine Oil Pressure Switch

Engine Oil Pressure Switch for OE Replacement

Walker 256-1077 is an OE replacement engine oil pressure switch built to monitor lubrication pressure and send a signal to the ECU or dashboard warning circuit when pressure drops below safe limits. It is a direct-fit solution for select Audi and Volkswagen applications, including Audi A6 Quattro, A7 Quattro, A8 Quattro, Q5, Q7, and Volkswagen Touareg models.

Key Features

• OE replacement engine oil pressure switch for factory-style pressure monitoring
• Matches OE specifications for pressure threshold, thread size, terminal type, and electrical response
• Plastic gray housing with a spade terminal design
• 1 female connector and 2 male terminals for direct wiring connection
• High-temperature, oil-resistant construction for engine bay exposure
• Direct-fit design for installation at the factory oil pressure switch location
• Walker 256-1077 for Audi and Volkswagen oil pressure switch replacement

Detailed Description

Walker 256-1077 is engineered for accurate oil pressure monitoring in vehicles that rely on a switch-style warning circuit. It threads into the original mounting location, typically on the engine block or oil filter housing, and connects to the existing harness without modification. This part is built to match OE fit and electrical behavior, making it a practical choice for service work, drivability repairs, or engine rebuilds on 2013-2016 Volkswagen Touareg, 2014-2016 Audi A6 Quattro, 2014-2016 Audi A7 Quattro, 2014-2016 Audi A8 Quattro, 2014-2016 Audi Q5, and 2013-2016 Audi Q7 applications. The Walker 256-1077 oil pressure switch helps maintain proper warning-system function when the original unit no longer responds correctly.

What It Helps Address

• Oil warning light flickering or intermittent illumination
• False low-oil-pressure warnings
• No warning signal when actual oil pressure drops
• Faulty switch response caused by heat and oil exposure
• Loss of factory oil pressure monitoring on Audi and Volkswagen models

Installation Notes and Tips

Verify the pressure threshold, thread size, and connector style before installation. This switch uses a spade terminal layout with one female connector and two male terminals, so it should match the original electrical connection on the vehicle. Install at the factory oil pressure switch location and inspect the harness and sealing surface during service. For fitment-specific applications, confirm the notes listed for Volkswagen Touareg 2013-2016 and Audi Q7 2015 models, which specify 0.75-1.05 BAR.

Quality Assurance

Walker manufactures this oil pressure switch to OE replacement standards using materials selected for high-temperature and oil exposure conditions. Part number 256-1077 is built for consistent electrical response and factory-style fit across the listed Audi and Volkswagen applications.
