Keep close watch on your engine's lubrication with the Walker Products Engine Oil Pressure Switch 256-1048 (also written 2561048), an OE-replacement switch that monitors oil pressure and signals the driver or ECU when levels fall below safe operating thresholds. It's a direct-fit replacement for many 1995-1999 Audi and Volkswagen applications, including the 1995 Audi 90, 1995 Audi 90 Quattro, 1995-1997 Audi A6, 1995-1998 Audi A6 Quattro, 1995-1998 Audi Cabriolet, 1995-1998 Volkswagen Cabrio, 1995 and 1997 Volkswagen EuroVan, 1995-1998 Volkswagen Golf, 1995-1999 Volkswagen Jetta, and 1995-1997 Volkswagen Passat. See the "Vehicles it fits" section for the full engine-level list.
- Monitors oil pressure levels: Activates the dashboard warning or ECU input when oil pressure drops below safe operating thresholds.
- OE-replacement calibration: Made to match original specs for pressure activation point, thread pitch, and electrical response.
- Built for harsh conditions: Made with high-temperature and oil-resistant materials to resist heat, oil exposure, and vibration.
- Threaded install: Threads into the factory location using original threads and connectors with no modifications required.
If a failed oil pressure switch is behind a flickering oil light, false warnings, or no signal under actual low-pressure conditions, this unit restores that early-warning function.
