GPD 1815261
Single-wire low-oil-pressure warning-light switch with M10 × 1.0 thread, blue insulator and nominal 0.25 bar threshold.
GPD 1815261 is a low engine-oil-pressure warning-light switch. It is a binary pressure-operated electrical contact: it controls the warning lamp when adequate pressure is absent and changes contact state as oil pressure rises. It does not transmit a proportional pressure value to an analog gauge.
Application / fitment
The part corresponds to Volkswagen/Audi OE 028 919 081 D and appears in selected Alfa Romeo, Audi and Volkswagen vehicles. Confirm the OE number, blue insulator, M10 × 1.0 thread and required switching threshold.
- part type: low oil pressure warning-light switch
- operating principle: binary pressure-operated switch
- selected Alfa Romeo Spider and Milano applications
- selected Audi 80, 90, 100, 200 and V8 applications
- selected Volkswagen Golf, Jetta, Passat, Scirocco, Transporter and EuroVan applications
- OE / interchange number: 028 919 081 D
Measure actual oil pressure with a mechanical gauge before replacement because an illuminated warning lamp can indicate an engine fault rather than a failed switch. The metal housing provides the electrical ground, so thread sealant must not electrically isolate the switch from the engine.
