Keep an early eye on engine lubrication with the Walker Products Engine Oil Pressure Switch 256-1077, an OE-replacement sensor that monitors oil pressure and signals the ECU or dashboard warning light when levels fall below safe operating thresholds. It threads directly into the factory location and connects to the existing wiring for the 2014-2016 Audi A6 Quattro, 2014-2016 Audi A7 Quattro, 2014-2016 Audi A8 Quattro, 2014-2016 Audi Q5, 2013-2015 Audi Q7, and 2013-2016 Volkswagen Touareg — see the Buyer's Guide tab for engine-level fitment.
Monitors oil pressure: activates the dashboard warning or ECU input when pressure drops below safe operating thresholds.
Built for harsh conditions: made with high-temperature and oil-resistant materials to resist heat, oil exposure, and vibration.
OE-replacement calibration: matches original specs for pressure activation point, thread pitch, and electrical response.
Direct installation: uses the original threads and connectors, so no modifications are required.
Acting as a critical warning device, the switch helps protect internal components by alerting the driver or control system to low-oil-pressure conditions. If a failing oil pressure switch is the cause of a flickering oil light, false warnings, or a missing signal, this unit replaces it — diagnose the cause before installing.
