What are the consequences of poor-quality AdBlue® for vehicles?

AdBlue® products are essential for modern diesel engines equipped with an SCR system. But when their quality does not meet the standards, side effects soon follow — and they’re usually expensive. In today's blog article, we look at the real risks to your car when using poor-quality or counterfeit products and why it’s important to use only certified AdBlue®.

What is “poor-quality AdBlue®”?

Poor-quality AdBlue® may have some of the following characteristics: incorrect urea concentration (less than 32.5%), presence of impurities — dust, oils, ammonia, or other contaminants — and most importantly, unknown origin or misleading labeling!

What are the consequences for the engine and SCR system?

  • Injector and catalyst clogging
    Impurities or incorrect formula can lead to crystal build-up that blocks system operation.

  • Increased fuel consumption
    The SCR system cannot function properly, affecting overall engine efficiency.

  • Warning lights and limp mode activation
    When a problem is detected, the vehicle’s onboard computer may limit power or even prevent restarting.

  • Expensive repairs
    Damage to the catalyst, sensors, or injection system can cost thousands.

Impact on the environment and emission compliance

When AdBlue® is not injected properly or is ineffective, harmful nitrogen oxide (NOx) emissions increase significantly. This violates environmental standards and may lead to:

  • Failed technical inspections;

  • Penalties for fleet operators;

  • Loss of trust from partners and clients.

How to protect yourself?

  • Refill only from verified sellers or BAMIA partners;

  • Check for clear labeling and compliance with ISO 22241;

  • Avoid suspiciously low prices and unmarked containers.

If you suspect you’ve encountered poor-quality AdBlue® — do not use it. You can report it directly on the BAMIA website.

The quality of AdBlue® is not a detail — it’s a critical factor for safety, environmental protection, and the longevity of every diesel vehicle. At BAMIA, we actively work to control the market and maintain high standards. Your informed choice matters!
