What causes an AdBlue injector to fail?

2025-11-12

An AdBlue injector can fail due to several reasons, primarily related to contamination, electrical issues, or mechanical wear. Here are the common causes:

  1. Contamination‌: Impurities in the AdBlue fluid (e.g., dirt, debris, or incorrect fluid) can clog the injector nozzle or damage its internal components‌4.
  2. Electrical faults‌: Wiring issues, sensor failures, or problems with the electronic control module (ECM) can disrupt the injector's operation‌4.
  3. Mechanical wear‌: Over time, the injector's moving parts may degrade, leading to leaks or poor spray patterns‌4.
  4. Freezing or crystallization‌: AdBlue can crystallize in cold temperatures, blocking the injector if the system isn't properly heated‌4.
  5. System leaks‌: Damaged hoses, loose connections, or cracks in the injector housing can cause fluid loss and failure‌4.

Regular maintenance, using high-quality AdBlue, and addressing warning lights promptly can help prevent these issues. For complex faults, professional diagnosis is recommended‌
