The VDO Oil Pressure Sender Unit (0-5 Bar) is designed for automotive enthusiasts and professionals requiring precise pressure monitoring for oil, fuel, or air systems. It provides accurate gauge readings while incorporating a vital 0.4 bar warning contact for early detection of pressure drops. While highly reliable, users must ensure their vehicle's port matches the 1/8 NPTF thread specification, as additional adapters may be required for specific engine blocks.

It is designed specifically for VDO electrical gauges. Using it with other brands may result in incorrect readings due to different resistance curves.
Yes, this unit is compatible with oil, fuel, and air pressure monitoring.
The warning contact acts as a switch that completes an electrical circuit to a warning light when the pressure drops below 0.4 bar.
You can use a small amount of conductive sealant, but avoid heavy use of thick Teflon tape as it can interfere with the ground connection required for the sensor.
Not directly. You would need a 1/8 NPTF to M10x1 adapter to make it fit.
No, this specific model is a common ground sensor, meaning the body of the sender must be grounded to the engine.
Check if the wire is securely connected to the sender terminal and verify that the sender is threaded into a grounded metal surface.
Verify if the oil pressure is actually low; if pressure is normal, the internal 0.4 bar switch may be faulty or the wire may be shorted to the engine ground.
Ensure the electrical connection is clean and free of corrosion, and check for a solid engine-to-chassis ground strap.
Installation requires a 1/8 NPTF threaded port. Because this is a 'common ground' sensor, the unit must be threaded into a grounded, conductive metal part of the engine to function. If you are installing this in a location that lacks a ground, or if you need to retain a factory sensor in the same port, you must purchase a T-piece adapter. When installing, apply a small amount of thread sealant suitable for automotive sensors, but ensure it does not coat the very first threads to maintain electrical continuity for the ground connection. Periodically inspect the wire connection to the terminal for corrosion to ensure the gauge reading remains steady.
