The Topran 113750 is a green low-pressure oil pressure switch designed for selected Volkswagen and Audi engines. It monitors oil pressure at the lower end of the system and helps trigger the oil warning light when pressure drops too low for safe lubrication. Available at Dub Source Limited, Kingston’s dedicated Volkswagen and Audi parts specialist in Jamaica.

WHAT IT IS

This is a low-pressure oil switch, often identified by its green or dark green plastic housing. It is part of the engine’s oil pressure monitoring system and acts as an early warning device when oil pressure falls below the minimum level needed to protect internal engine components.

Unlike a sensor that sends a wide range of pressure data, this switch is designed to react when pressure reaches a critical low point. When that happens, it signals the vehicle’s warning system so the driver can respond before serious engine damage occurs.

WHY IT MATTERS

Oil pressure is what keeps the crankshaft, camshaft, bearings, and other moving parts separated by a protective oil film. If pressure drops too low, metal parts can begin making direct contact, which can quickly lead to serious internal engine damage.

A faulty low-pressure switch can create two different problems. It may trigger a false oil pressure warning when pressure is actually normal, or it may fail to warn the driver when pressure is genuinely low. Either issue should be checked properly, because oil pressure warnings are never something to ignore.

COMMON SIGNS OF A FAULT

Common signs of a failing oil pressure switch include an oil warning light that stays on, an oil warning that appears at idle, an intermittent warning that comes and goes, or no warning when there is a known pressure issue. On older Volkswagen and Audi vehicles, heat, age, and oil contamination can also affect the switch and connector area over time.

In Kingston traffic where engines often sit idling in heat, low-pressure monitoring is especially important. The engine spends more time at lower RPM, where oil pressure is naturally at its lowest point in normal operation.

COMPATIBILITY

The Topran 113750 fits selected Volkswagen and Audi models. Oil pressure switch fitment depends on engine code, oil circuit design, pressure rating, and connector type.
