Product Information

Full details

The Febi Bilstein 103908 Oil Pressure Switch is an essential replacement component for owners and mechanics maintaining heavy-duty MAN and Neoplan commercial vehicles. Engineered for precise oil pressure monitoring, this sensor ensures critical engine data is relayed accurately to the vehicle's onboard systems to prevent lubrication-related failures. While this part is manufactured to strict OEM standards for reliability, it is a technical component requiring specific mechanical knowledge, and it does not include installation instructions, making it most suitable for professional or experienced DIY repair environments.

Extended Product Information

FAQs

Is this sensor compatible with all MAN trucks?

No, it is specific to models like the TGA, TGX, and Lion's City. Always cross-reference your specific engine model.

Does this switch come with a gasket?

The switch is designed to seat using the integrated threading; ensure the mating surface on the engine block is clean.

What size socket do I need?

You need a 27 mm spanner or socket to install this unit.

Can I install this myself?

If you have experience with automotive sensors and have the appropriate tools, yes; otherwise, professional installation is recommended.

What is the thread specification?

The switch features an M18 x 1.5 thread.

How do I check if my current switch is faulty?

Common signs include erratic gauge readings or persistent dashboard oil pressure warnings despite proper oil levels.

Troubleshooting

Sensor showing incorrect pressure reading

Verify the electrical connector is seated firmly and the pins are free from corrosion.

Oil leaking from the mounting base

Ensure the thread is tightened to the manufacturer's torque specification; re-seat the sensor if necessary.

Dashboard warning light remains on

Confirm that the oil levels are correct and use an OBD diagnostic tool to clear old error codes that may be stored in the ECU.

Pros and Cons

Pros

  • High manufacturing standards ensuring reliability
  • Direct compatibility with MAN and Neoplan vehicle models
  • Sturdy housing built for heavy-duty applications
  • Precise M18 x 1.5 threading for secure mounting

Cons

  • No installation manual included in the package
  • Requires mechanical expertise for safe installation
  • Compatible only with specific heavy-duty vehicle series

Setup, Compatibility & Care

Before installation, verify that your vehicle identification number (VIN) matches the compatibility list for MAN and Neoplan models, such as the TGA, TGX, or Lion's City series. Installation requires access to the oil pressure gallery; ensure the engine is completely cool and depressurized before attempting removal of the existing switch. Use a 27 mm socket to carefully remove the old unit and install the new switch, ensuring the threads are aligned correctly to prevent cross-threading. Always verify the electrical connection is snapped firmly into the 3-pin connector. It is recommended to check for oil leaks around the mounting point after the engine has run for several minutes at idle. Keep the electrical pins free of grease and debris during installation to maintain signal integrity.
