FAQs

How often should I change this filter?

You should follow the replacement intervals specified in your vehicle manufacturer's maintenance manual, usually coinciding with standard service cycles.

Is the gasket included in the box?

Yes, this filter comes complete with the necessary gaskets and seals for a standard installation.

Can I wash and reuse this filter?

No, this is a single-use filter and must be replaced entirely to ensure system performance and prevent contamination.

Does this fit all AdBlue systems?

No, this filter is specifically designed for systems requiring the U 620/2 y specification; verify your part number before purchase.

What happens if I don't change the urea filter?

Neglecting the filter can lead to crystallization and sediment buildup, which may eventually cause the urea pump to fail or the SCR injection system to clog.

Troubleshooting

Dashboard warning light persists after filter change

Verify the installation is secure and check for air leaks in the housing; clear error codes using an OBD-II diagnostic scanner.

Housing cap is difficult to remove

Do not force the cap. Apply a small amount of penetrating lubricant to the threads and use the correct sized socket to prevent rounding the plastic cap.

Noticeable fluid leak after installation

Remove the cap, check that the included O-ring is properly seated in its groove, and ensure the surfaces are clean before re-tightening.

Pros and Cons

Pros

  • High chemical resistance against AdBlue/Urea fluids
  • Includes necessary gaskets and seals for a leak-free installation
  • Exact OEM-spec dimensions ensure a secure housing fit
  • Prevents costly damage to urea injection pumps and nozzles

Cons

  • Requires specific tool access for housing removal in some vehicle models
  • Sensitive to contamination during the installation process
  • Not compatible with standard diesel or oil filtration housings

Setup, Compatibility & Care

To install the filter, ensure the vehicle's ignition is off and the SCR system is depressurized. Carefully unscrew the filter housing using the appropriate wrench to avoid cracking the plastic cap. Remove the old element and discard it according to local chemical disposal regulations. Clean the interior of the housing with a lint-free cloth, ensuring no fibers remain. Seat the new U 620/2 y filter, install the provided new gasket, and tighten the cap to the manufacturer's specified torque to prevent leakage. Avoid over-tightening as this can warp the seal.
