Frequently asked questions

About this category

The 1.6 TDI 105 hp diesel engine, widely used in compact and mid-size vehicles, relies on a high-pressure pump to deliver fuel at the correct pressure to the injectors. This category includes remanufactured exchange parts designed to restore engine efficiency when the original pump fails. Whether for a professional repair or a DIY enthusiast, these pumps ensure the engine receives the precise fuel volume needed for optimal performance.

The range is built around verified OEM references, sourced from suppliers who specialize in remanufacturing fuel systems. Each pump undergoes a standardized process to restore its internal components, ensuring it meets the original performance standards. The role of the wholesaler is to provide these parts in bulk, with clear compatibility data, so garages can maintain their inventory efficiently.

How to choose

Selecting the right high-pressure pump involves checking compatibility with the vehicle’s motorisation, power output, and fuel system specifications. Professionals should also consider the pump’s condition and the supplier’s remanufacturing process to ensure reliability.

  1. Verify the pump’s compatibility with the 1.6 TDI 105 hp engine by cross-referencing the motorisation code and power output to avoid mismatches.
  2. Assess the pump’s condition by requesting documentation on its remanufacturing process, ensuring it meets original performance standards.
  3. Check the supplier’s stock rotation to deliver the pump is recent and has not been stored for extended periods, which can affect its longevity.
  4. Confirm the pump’s packaging and labeling to ensure it is clearly marked for the correct motorisation and power output, avoiding installation errors.
  5. Prioritize suppliers who provide clear return policies for used cores, simplifying the exchange process and reducing logistical hassles.
  6. Evaluate the pump’s physical condition, such as the condition of the cartridge and CHRA, to ensure it is free from corrosion or wear that could impact performance.
  7. Review the supplier’s reputation for consistent quality, as this directly influences the pump’s reliability and the engine’s long-term performance.

Storage & logistics

High-pressure pumps must be stored in a dry, temperature-controlled environment to prevent moisture damage or corrosion to internal components. Garages should rotate stock regularly to ensure older units are used first, maintaining freshness and reliability. For bulk orders, palletized storage with protective covers is recommended to shield the pumps from dust and physical damage, preserving their condition until installation.
