Bosch Denoxtronic 5 series supply pump replacement kit

Since the manufacture of the first diesel truck in 1924, and the first diesel car in 1936, Bosch has been one of the world’s leading providers of diesel technology.

Denoxtronic, the Bosch exhaust-gas treatment system is being used in the majority of diesel vehicles with increasing significance for the independent aftermarket vehicle workshop.

The system injects the Diesel exhaust fluid, commonly known as Diesel Exhaust Fluid (DEF), urea solution or AdBlue, into the exhaust-gas stream. In combination with the catalytic converter, the system converts harmful nitrogen oxides (NOx) into water and nitrogen.

The latest Denoxtronic systems for passenger cars and light commercial vehicles is the 5 series generation, this generation typically consists of a supply module which is attached to the DEF tank via a plastic welding process which fuses the tank and the supply module into one unit.

In the aftermarket, for many repair cases, it is no longer required to replace the complete DEF tank and supply pump combination.

Bosch says it offers an affordable aftermarket solution consisting of a supply pump, dampers and mounting screws in the form of a kit – all the parts necessary for a successful supply pump replacement.

The Bosch supply pump kit part number can be identified using the vehicle model information in TecDoc or other selected electronic cataloging systems. The supply pump kit can be found by searching in the catalogue categories Exhaust Systems and/or Urea Injection.
