Keep tabs on engine oil pressure with the Beck/Arnley Engine Oil Pressure Switch 201-1078 — an oil-pressure switch with a warning-light function ("OIL PRESS SW W/LIGHT"). It drops in as a direct-fit replacement across a wide range of classic European vehicles, including the 1972-1974 Alfa Romeo Berlina, 1970-1988 Alfa Romeo Spider, 1968-1976 BMW 2002, 1965-1969 Porsche 912, 1962-1979 Volkswagen Beetle and 1957-1979 Volkswagen Transporter. With 29 applications spanning Alfa Romeo, Audi, BMW, Porsche and Volkswagen, see the "Vehicles it fits" section for the full list.
This switch senses engine oil pressure and controls the dashboard oil warning lamp's circuit; when pressure falls below its set point, it signals the warning light. If a failed switch is the cause of a light that stays on, won't illuminate, or flickers, this replaces it — diagnose the cause before replacing.
