Keep tabs on engine lubrication with the Walker Products Engine Oil Pressure Switch 256-1072 (also written 2561072), an OE-replacement switch that monitors oil pressure and signals the ECU or driver when levels fall below safe operating limits. It's a direct-fit replacement for a wide range of Audi and Volkswagen applications, including the 2006-2008 Audi A3, 2005-2009 Audi A4 and A4 Quattro, 2006-2009 Audi A6, 2005-2008 Audi A6 Quattro, 2008-2009 Audi TT, 2009-2015 Audi TTS Quattro, 2006-2010 Volkswagen Beetle, 2007-2009 Volkswagen EOS, 2010-2014 Volkswagen Golf, 2006-2008 Volkswagen GTI, 2005-2014 Volkswagen Jetta, 2006-2008 Volkswagen Passat, and 2006-2009 Volkswagen Rabbit — see the "Vehicles it fits" section for the full list.
- OE Replacement Calibration: Matches original specs for pressure activation point, thread pitch, and electrical response.
- Monitors Oil Pressure: Activates the dashboard warning or ECU input when oil pressure falls below safe operating thresholds.
- Helps Protect the Engine: Alerts the driver or control system to low-oil-pressure conditions so problems can be addressed early.
- Built for Harsh Conditions: Made to resist high temperatures, oil exposure, and vibration in demanding engine environments.
Designed for exact OE fit, it threads directly into the factory location—typically the engine block or oil filter housing—and connects to existing wiring with no modifications. Signs the original may need replacing include an oil light that flickers, false warnings, or no signal under actual low-pressure conditions. If a failed switch is the cause of those symptoms, this unit replaces it.
Frequently Asked Questions
What does the Walker 256-1072 switch do?
It monitors engine oil pressure and activates the dashboard warning light or feeds a signal to the ECU when pressure falls below safe operating thresholds, providing early warning of low-lubrication conditions.
Which vehicles does this switch fit?
It's a direct-fit replacement for many 2005-2015 Audi and Volkswagen models, including the A3, A4, A4 Quattro, A6, A6 Quattro, TT, TTS Quattro, Beetle, EOS, Golf, GTI, Jetta, Passat, and Rabbit. See the "Vehicles it fits" section.
Where does the oil pressure switch install?
It's designed for exact OE fit and threads directly into the factory location—typically the engine block or oil filter housing—connecting to the existing wiring with no modifications required.
What are signs my oil pressure switch may be failing?
Common signs include an oil light that flickers, false warnings, or no signal under actual low-pressure conditions. Diagnose the cause before replacing, since low oil pressure can have other sources.
Is this an OE-replacement part?
Yes. Walker builds it as an OE-replacement component calibrated to match original specifications for the pressure activation point, thread pitch, and electrical response.
