FAQs

What does 'Normally Closed' mean for this switch?

A 'Normally Closed' contact means that the electrical circuit connected to the switch is complete (closed) when the oil pressure is low (below the activation threshold). When the oil pressure reaches the specified level (0.15-0.35 bar), the switch opens the circuit, turning off the connected indicator light.

Which vehicle models is this switch compatible with?

This switch is suitable for various VW, Audi, Skoda, and Seat models including Golf MK1, MK2, MK3, Scirocco, Corrado, Passat, Transporter T3, T4, LT 28-35, LT 28-46, Audi 80, 100, A4, A6, A8, Skoda Felicia, and Seat Alhambra, Ibiza, Cordoba, Inca, Toledo. Always verify compatibility with your specific vehicle's year and VIN range.

What is the activation pressure range for this switch?

The activation pressure range for this MEYLE oil pressure switch is 0.15 to 0.35 bar.

What are the thread and spanner sizes?

The switch has an M10 x 1.0 thread size and requires a 24mm spanner for installation or removal.

Can I use this switch if my original part number is different?

This switch replaces original part numbers 028919081D and 028919081H. If your original part number is different, it is essential to confirm cross-compatibility through a vehicle parts catalog or specialist.

How often should I check my oil pressure switch?

The oil pressure switch itself does not require routine checks. However, it's good practice to visually inspect its electrical connection for corrosion during regular maintenance. The primary indicator of its function is the dashboard warning light.

What tools are needed for installation?

You will typically need a 24mm wrench or socket, and potentially a small flathead screwdriver for disconnecting the electrical connector. It's also advisable to have thread sealant on hand if recommended for your specific vehicle.

Troubleshooting

Oil pressure warning light stays on after engine start.

Verify the switch is correctly installed and tightened. Check the electrical connection. If the issue persists, the engine may have a genuine low oil pressure problem or the new switch may be faulty.

Oil pressure warning light flickers during operation.

This can indicate a borderline low oil pressure situation. Check the engine oil level and condition. Ensure the switch is properly tightened. If oil level is correct, it may point to a worn oil pump or internal engine wear.

Switch leaks oil after installation.

Ensure the threads were properly cleaned and that the switch was tightened correctly without cross-threading. Check if thread sealant was used appropriately (if required). The switch itself may be defective.

Incorrect part fitted, causing fitment issues.

Double-check the part number and vehicle compatibility. Ensure the thread size (M10 x 1.0) and spanner size (24mm) match the requirement.

Pros and Cons

Pros

  • Durable construction meeting original quality standards.
  • Direct replacement for specific OE part numbers (028919081D, 028919081H).
  • Relatively straightforward installation for experienced DIYers or mechanics.
  • Helps prevent engine damage by accurately signaling low oil pressure.

Cons

  • Compatibility is limited to specific vehicle models and years; requires careful verification.
  • Only suitable for models requiring this specific pressure range and thread size.
  • May require removal of other components for access during installation.
  • Only one pin connection, not suitable for multi-function sensors.

Setup, Compatibility & Care

Compatibility Check: Before installation, verify that your vehicle is listed as compatible and that this switch replaces your original part number (028919081D or 028919081H). Consult your vehicle's service manual or a parts specialist to confirm fitment based on Year, Make, Model, and VIN.

Installation:

  1. Ensure the engine is cool and disconnected from the battery.
  2. Locate the existing oil pressure switch on the engine block.
  3. Use a 24mm wrench to carefully unscrew the old switch.
  4. Clean the threaded port on the engine block.
  5. Apply a small amount of thread sealant (if recommended by vehicle manufacturer) to the new switch's threads.
  6. Screw in the new MEYLE switch by hand to avoid cross-threading, then tighten gently with the 24mm wrench.
  7. Connect the electrical connector to the single pin.
  8. Reconnect the battery and start the engine. Check for leaks and ensure the oil pressure warning light functions correctly.

Care: This is a sealed component and requires no routine maintenance. However, ensure the electrical connection remains clean and free of corrosion for optimal performance.
