How to choose
Selecting the right turbocharger for your 1.9 TDI 90 hp depends on several factors, including remanufacturing quality, core deposit policies, and compatibility with your vehicle’s engine code.
- Prioritize turbos with documented remanufacturing processes, such as laser welding and bearing upgrades, to ensure longevity and performance consistency.
- Check the core deposit policy to avoid unexpected fees; some suppliers offer refundable deposits for returned cores, simplifying logistics.
- Verify compatibility with your engine code (e.g., AGR, ALH, or AHF) to prevent fitment issues, as slight variations exist even within the 1.9 TDI family.
- Opt for turbos packaged in protective casings to prevent damage during transit, especially for DIY buyers handling their own deliveries.
- Choose suppliers with transparent return policies for defective units, as this reduces risk when ordering unseen parts in bulk.
- Select turbos with clear documentation in your preferred language, whether French, English, or German, to ease installation and warranty claims.
- For garages, prioritize turbos with consistent lead times to avoid delays in customer vehicle turnaround and maintain service reliability.
Storage & logistics
Exchange standard turbos for the 1.9 TDI 90 hp must be stored in climate-controlled environments to prevent moisture buildup in the CHRA, which can lead to premature bearing wear. For bulk buyers, palletized storage with desiccant packs ensures parts remain in optimal condition until installation, while individual units should be kept in sealed bags to avoid contamination. Regular inventory rotation prevents stagnation, and core deposits should be logged separately to track returns and refunds efficiently.
