The Delphi SW90025 is a black high-RPM oil pressure switch designed for selected Volkswagen and Audi engines. Available at Dub Source JA, Kingston’s dedicated VW and Audi parts specialist in Jamaica. WHAT IT IS On Volkswagen and Audi engines, the oil pressure monitoring system typically uses two separate switches rather than one. Each switch is responsible for a different pressure range and a different operating condition. The black switch, which is this unit, monitors oil pressure at higher engine speeds where greater pressure is expected. It is calibrated to trigger at approximately 1.2 to 1.6 bar and operates as a gatekeeper that confirms the engine is maintaining adequate oil pressure during harder driving or sustained high RPM use. The second switch in the system, usually identified by a different colour, handles the low-pressure monitoring at idle and low engine speeds. WHY IT MATTERS Oil pressure is what keeps the moving parts inside your engine separated by a protective film of oil. When pressure drops below the minimum required threshold and the switch does not detect it correctly, the ECU and warning systems lose the ability to alert the driver before damage occurs. A faulty or failed black oil pressure switch can cause a false oil pressure warning light on the dashboard, or worse, allow the engine to run with genuinely low pressure at high RPM without triggering any warning at all. Either way, the switch is a critical part of the engine’s self-protection system and should be replaced with the correct unit when it fails. COMPATIBILITY The Delphi SW90025 fits selected Volkswagen and Audi models. Oil pressure switch fitment is specific to engine code and oil circuit design.
