Fuel injector VOLKSWAGEN Touran 2 (1T3) 1.6 TDI 105 hp

The 1.6 TDI 105 hp diesel engine, found in models from 2009 to 2015, relies on a precise fuel injection system where even minor deviations in injector performance can lead to drivability issues. This category provides reconditioned injectors designed specifically for this motorization, addressing common symptoms like misfires, rough idling, or excessive fuel consumption. Whether you are a professional mechanic replacing a faulty unit or a car owner tackling the repair yourself, these parts offer a cost-effective alternative to new OEM injectors.

The range is built around core components like the Siemens-VDO 5WS40539 injector, selected for its widespread use in this engine family. As a wholesale supplier, we source these parts from certified remanufacturers who restore them to original specifications, ensuring compatibility and longevity. The process includes rigorous testing for spray pattern, leakage, and electrical integrity, with each unit backed by a traceable history. This approach bridges the gap between OEM quality and aftermarket affordability, making it ideal for garages and DIYers alike.

Professional uses by trade

This section compares the available reconditioned injectors for the 1.6 TDI 105 hp, highlighting their compatibility, condition, and intended use cases. Each option is presented with clear details to guide your selection.

How to choose

Selecting the right injector involves more than just matching the part number. Consider factors like condition, testing standards, and packaging to ensure a seamless replacement process.

1. Condition: Opt for units labeled as 'generalüberholt' or 'remanufactured,' indicating they have been restored to original performance levels.
2. Testing: Prioritize injectors that include documented tests for spray pattern, electrical resistance, and leakage to avoid premature failures.
3. Packaging: Choose parts shipped in protective, anti-static containers to prevent damage during transit, especially for bulk orders.
4. Compatibility: Verify the injector’s fit by cross-referencing the engine code (e.g., CAYA, CFFB) and model year to avoid mismatches.
5. Core deposit: For garages, systems that include a refundable deposit for returned cores simplify logistics and reduce costs.
6. Brand reputation: Select injectors from reputable remanufacturers with a track record in diesel fuel systems to ensure reliability.
7. Documentation: Ensure the part comes with a traceable history, including the original engine application and remanufacturing date.

Storage & logistics

For B2B buyers, proper storage of reconditioned injectors is critical to maintaining their condition until installation. These parts should be kept in a climate-controlled environment, away from moisture and direct sunlight, to prevent corrosion or seal degradation. Organize inventory by engine code and model year to streamline picking and reduce errors during order fulfillment. Use anti-static bags for individual units and sturdy, labeled boxes for bulk shipments to protect against physical damage. Regularly audit stock to ensure no units exceed their recommended shelf life, and rotate inventory to prioritize older stock. This approach minimizes waste and ensures every injector meets the high standards required for diesel fuel systems.

Since 2026, our team has processed hundreds of these injectors, refining our selection process to focus on consistency and compatibility. We’ve seen firsthand how a well-chosen reconditioned injector can restore a 1.6 TDI 105 hp to near-original performance, often at a fraction of the cost of a new unit.— autoKUR team
