Walker 256-1121 Engine Oil Pressure Switch
Engine Oil Pressure Switch for OE-Style Monitoring
Walker 256-1121 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 feedback, including Audi A4 Quattro, A5 Quattro, A6, A6 Quattro, Q5, Q7, S4, S5, and Volkswagen Touareg applications with the gray 2-pin configuration.
Built to match factory pressure thresholds, thread size, terminal layout, and electrical response, this Walker oil pressure switch helps restore proper warning-light operation without wiring changes or fitment guesswork.
- OE replacement engine oil pressure switch for factory-style signal output
- Gray plastic housing with 1 female connector and 2 male spade terminals
- Direct-fit design for the original mounting location on the engine block or oil filter housing
- High-temperature, oil-resistant construction for engine bay exposure
- Walker 256-1121 for Audi and Volkswagen oil pressure warning system service
Detailed Fitment and Function
This engine oil pressure switch is used to monitor oil pressure and trigger the warning circuit when pressure drops below safe limits. Walker 256-1121 is engineered for exact OE-style electrical response, making it a practical replacement when the original switch causes flickering oil lights, false warnings, or no warning signal during a true low-pressure condition. It is a direct replacement for select 2008-2014 Audi and Volkswagen models, including Fits 2011-2014 Volkswagen Touareg, N/A; Fits 2010-2013 Audi S4, N/A; Fits 2012-2013 Audi S5, N/A; Fits 2009-2012 Audi A6 Quattro, N/A; Fits 2009-2012 Audi Q5, N/A; Fits 2011-2012 Audi Q7, N/A; Fits 2010-2011 Audi A6, N/A; Fits 2009 Audi A4 Quattro, N/A; and Fits 2008-2009 Audi A5 Quattro, N/A. This part number, 256-1121, is built for the gray 2-pin application noted in the fitment data.
Common Issues This Part Can Address
- Oil pressure warning light flickering at idle or while driving
- False low-oil-pressure warnings on the instrument cluster
- No warning signal when oil pressure drops below safe limits
- Faulty oil pressure switch signal to the ECU or gauge circuit
- Intermittent electrical response from a worn factory switch
Installation Notes and Tips
Install the switch in the original threaded location and verify the connector style before installation. The gray 2-pin design should connect to the existing factory harness without modification. Confirm the engine application and thread specification against the removed part before final assembly, and inspect the surrounding oil filter housing or engine block area for leaks or damaged wiring while servicing the switch.
Quality Assurance
Walker manufactures this OE replacement switch to match factory specifications for pressure threshold, terminal type, and electrical response. The design uses oil-resistant, high-temperature materials to support consistent operation in engine environments and restore dependable oil pressure monitoring on Audi and Volkswagen applications.
