    Keep an early warning on engine oil pressure with the Walker Products Engine Oil Pressure Switch 256-1078. This OE-replacement switch drops in for the listed applications, including the 2007-2011 Audi A6 Quattro, the 2007-2010 and 2012-2016 Audi A8 Quattro, the 2007-2010 Audi Q7, plus Audi R8, S5, S6, S8 and Volkswagen Touareg models — see the "Vehicles it fits" section for the full year list.

    • OE-replacement calibration: matches the original pressure activation point, thread pitch, and electrical response.
    • Built for harsh conditions: made with high-temperature and oil-resistant materials to stand up to heat, oil exposure, and vibration.
    • Monitors oil pressure: activates the dashboard warning light or feeds a signal to the ECU when pressure falls below safe operating thresholds.
    • Connection: single male terminal with one female connector; black plastic housing.

    Mechanically, this switch senses engine oil pressure and signals the driver or engine control system when it drops, helping give early warning of a low-lubrication condition. It threads into the factory location — typically the engine block or oil filter housing — using the original threads and connector with no modifications. If a faulty original switch is behind a flickering oil light, false warnings, or a missing signal, replacing it with 256-1078 restores that warning function. Manufacturer part number 256-1078 (also 2561078). Country of origin: Italy.
