Diesel parts

When a part is repaired, quality components are used. They are also supplied separately to workshops and to anyone repairing on their own: nozzles, valves, repair kits and sensors, both original and aftermarket.

An original part is one produced by the manufacturer of the system (for example Bosch, Denso or Delphi). Aftermarket parts are made by third parties with varying levels of quality. In precision parts such as nozzles or valves, the quality of the material and of manufacturing determines how long a repair lasts, so compatibility with the part number is the first criterion.

To quote accurately, the number stamped on the part is needed, or a clear photo of the part and of the vehicle plate. In diesel injection, two similar looking parts can have different calibrations, so it is best not to rely on appearance alone.
