Adblue pump failures are very common in commercial vehicle and public transport sectors. Failures in the main come from a lack of maintenance of the systems, lack of maintenance can cause crystallisation issues which also lead to the system not operating correctly. Other failures can range from communication faults, Oil, coolant or fuel contamination, blowing fuses, water Ingress, various intermittent faults, various sensor faults, fault codes In units, connector and pin damaged.
Adblue pump costs can range dependant on what’s requested from the unit its self. If we a traditionally pumping unit the costs are lower than that of a unit that is programmed specifically to the vehicles chassis.
Pumps on a bus/coach would be located at the rear of the vehicle close to the exhaust system and in contrast to a truck these would be located on the chassis of the tractor unit toward the second axle close enough to the exhaust system.
Diesel engines are now required to meet strict NOx levels to comply with emission zone standards set out by local governments. The preferred method involves injecting a urea based chemical, more commonly named Adblue, directly into the exhaust system.
Adblue components are very susceptible to failure if misuse occurs or they are not serviced in line with manufacturers recommendations. Adblue system common failures include using out of date Adblue, cross contamination from filling stations and not following recommended service intervals.
A system failure can be very costly to an operator. Misuse of the system can cause premature failure of the dosing modules and injectors. It is integral that these units are maintained and the fluid is free from any contamination in order to allow the system to operate effectively.
All products are extensively tested using state of the art specifically designed testing equipment to ensure all units meet all OE specification prior to use. Twelve months warranty is standard on all service exchange and repaired items. By using Alliance tested products and services the UK's largest fleet operators are witnessing huge expenditure savings.
