Walker 256-1112 Engine Oil Pressure Switch

Walker 256-1112 Engine Oil Pressure Switch

Walker 256-1112 is an OE replacement engine oil pressure switch built to monitor lubrication pressure and send the correct signal to the ECU or dashboard warning circuit. It is a direct-fit solution for vehicles that need accurate oil pressure monitoring, including select Audi A8 Quattro, RS7, S6, S7, S8 and Volkswagen Jetta, Beetle, and Passat applications.

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
• Metal and plastic construction with oil-resistant, high-temperature materials
• 1 blade pin terminal, 1 female connector, and 1 male terminal interface
• Direct installation at the factory oil pressure switch location
• Walker 256-1112 is built for consistent signal output under engine heat and oil exposure

Detailed Description

This Walker oil pressure switch is engineered to restore proper warning-system operation when the original switch no longer reports pressure accurately. It threads into the engine block or oil filter housing location used by the factory part and connects to the existing wiring without modification. The blue-bodied switch is specified for applications that require a 2.7-3.4 BAR pressure range, including 2015-2018 Audi A8 Quattro, 2015-2018 Audi S8, 2014-2018 Audi RS7, 2014-2018 Audi S6, 2014-2018 Audi S7, 2013-2018 Volkswagen Jetta, 2013-2017 Volkswagen Beetle, and 2014-2017 Volkswagen Passat. Walker 256-1112 supports accurate oil pressure signaling for vehicles where the warning light or ECU input depends on a properly functioning switch.

Common Issues This Part Can Address

• Oil pressure warning light flickering or staying on
• False low-oil-pressure warnings
• No warning signal when actual oil pressure drops
• Intermittent oil pressure signal to the ECU or gauge circuit
• Faults caused by a worn or heat-damaged factory switch

Installation Notes and Tips

Confirm the pressure range, connector style, and thread specification before installation. Replace the switch at the original mounting point and reuse the existing vehicle wiring connection. For best results, inspect the connector and surrounding oil passages for contamination or damage before installing the new unit.
