AdBlue systems are a standard feature of today's diesel exhaust gas purification systems. An additional system that supplements the already complex diesel exhaust technology and forms an additional source of error messages in the exhaust system.
The basic prerequisite for the proper functioning of AdBlue systems is the absolute purity of the AdBlue (urea) liquid used.
Unfortunately, this is not always taken into account. Vehicle users - especially in the commercial vehicle sector - transfer AdBlue liquid from filling systems into unsuitable containers such as old oil or fuel canisters, thus carrying reserves contaminated with hydrocarbons, which are then filled into the AdBlue tank.
Even the smallest contamination by hydrocarbons can trigger a fault message in the AdBlue system.
Therefore, the first step in fault diagnosis should be to test for contaminated AdBlue fluid.
The test strips offered here detect hydrocarbon contamination in all media such as water or AdBlue.
Oil test paper allows the rapid and reliable detection of oil contaminations. The sensitivity largely depends on the nature of the respective hydrocarbon.
