The Bosch electronic stability program (ESP) supports the driver in nearly all critical driving situations. It complements the functions of the anti-lock braking system (ABS) and the traction control system but can do considerably more. It detects vehicle skidding movements, and actively counteracts them. This considerably improves driving safety. The fundamental task of ESP is to prevent skidding. The possibilities offered by the ESP, however, go far beyond this. As ESP can build up braking pressure independently of the brake-pedal position, plenty of so-called value-added functions can be realized with ESP. These provide additional driving safety and allow the driver to experience enhanced driving comfort and driving agility.

Supplies the optimal amount of urea fluid (Diesel Exhaust Fluid or DEF) to dosing module.

Introduces urea fluid into exhaust system to reduce nitrogen oxides (NOx) emission levels

Ensures proper fluid temperature and thaws DEF when below 12°F
