LiquiMoly AntiCrystal Additive for AdBlue

Model: (Various brands) Various
Part: Checks and maintenance

Video tutorial

The video explains a common problem with Euro 6 diesel engines: the crystallisation of AdBlue within the injector and system. This phenomenon can cause malfunctions and warning lights to illuminate.

AdBlue tends to form crystals when it dries out or experiences temperature fluctuations. The crystals accumulate in the AdBlue injector and pipes, which can lead to the engine warning light coming on, error messages, reduced performance, and costly repairs, including injector or tank replacement.

The LiquiMoly AntiCrystal Additive is a specific additive for AdBlue that is added to the AdBlue tank and prevents the formation of crystallisations; if crystals have already formed, it dissolves and eliminates them effectively. Simply pour the product directly into the AdBlue tank: it works both as a preventative (for constant use) and as a treatment for already present crystals.

To remove the rear seat of a Hyundai Tucson, follow these steps. Start by moving the front seats to their most forward position to gain space.

Once unlocked, tilt the seat upwards and forwards to remove it from its position. Repeat this process for both sides of the rear seat.
