Keep a close watch on engine lubrication with the Walker Products Engine Oil Pressure Switch 256-1033, an OE Replacement component that monitors oil pressure and signals the dashboard warning light or ECU when pressure falls below safe operating thresholds. It drops in as a direct-fit replacement across a range of Audi and Volkswagen models, including the 2013-2016 Audi A4 Quattro, 2014-2018 A6 Quattro, 2011-2021 TT Quattro, 2015-2019 Volkswagen Golf R, and 2020-2021 Atlas Cross Sport — see the "Vehicles it fits" section for the full list.
- Monitors Oil Pressure: activates the dashboard warning or ECU input when oil pressure drops below safe thresholds.
- Built for Harsh Conditions: made with high-temperature and oil-resistant materials to resist heat, oil exposure, and vibration.
- OE Replacement Calibration: matched to original specs for pressure activation point, thread pitch, and electrical response.
- Direct OE Fit: threads into the factory location — typically the engine block or oil filter housing — using the original threads and connector, no modifications required.
If a failed oil pressure switch is the cause of a flickering oil light, false warnings, or a missing signal under actual low-pressure conditions, this unit replaces it. Whether the job is scheduled service, a drivability repair, or an engine rebuild, it helps restore dependable early-warning monitoring within the lubrication system.
