Bosch pumps

The Bosch pump is a vital part of every diesel engine, because its main role involves dosing fuel and starting the engine. You will find out more about what it is, how it works and what are the most common malfunctions below.

What is a Bosch pump and how does it work?
The Bosch pump, also known as a high pressure diesel pump, is the heart of every "diesel". The main function of this pump is the metered injection of fuel into the cylinders, which further drives the engine. The operation of this pump is done indirectly, connecting it to the crankshaft through gears, chains or toothed belts, which further drives the camshaft. Electronics play a key role in the regulation of this system, enabling precise fuel dosing and proper engine operation.

What are the most common failures of a Bosch pump and what are the repair costs?
Gasketing problems are a common problem at low temperatures, and the most common symptom is the inability to start the vehicle in the morning. Repair includes inspection of nozzle return hoses and replacement of worn rubber gaskets. The price of this repair can be up to 50 euros. Mechanical failures are manifested when the vehicle is started, and the main characteristic is the lack of gas and the emission of white smoke from the exhaust. The solution is a thorough cleaning of the pump, replacement of damaged parts and pressure adjustment, which can cost between 250 and 500 euros, depending on the extent of the failure. The complex electronic system of the Bosch pump can also cause problems with the fuel adjustment valve, as well as errors caused by a failure of the 5V voltage stabilizer. As this is one of the more important parts of the car that can cause serious consequences, deepen the breakdown, and therefore increase the cost of the repair, it is important to react quickly and visit the nearest service.
